Done (post above, as edit, sorry) And -- i do not know how's with your MIDI-commando the global setting for EXP-pedals. My global setting for ALL EXP-pedals in every unit is "global". And "normal polarity"

I inform you too that i contacted the 5th dec. the line 6 service, described them in the limits of 2000letters the prob, and the robot answered they will contact me within 3 days. What they did not, whyever. Perhaps tomorrow. Hopefully. My problem is that if i want to return my HX without problems and discussions, i must do that until the 15th of december, and that's in 6 days. I can then buy me another one, or an LT, or something completely different, or nothing. But if i let this date pass, i am delivred to the line 6 warranty-service in the land i live (they speak latino here) and really, that's something i would like to avoid, i do not trust the technicians here, nor the mason, nor the carmechanic nor the eclectrowhatever. And the more - i already checked that via google, the next line6 technical service here is more than 400km away. I would not drive that with my car, but use DHL or whatever. That would mean shipping-costs. If they then say my HX is ok, i will have to pay the return-shipping. #>*"-# Thank you, i prefer to return the unit the 15th for free and without discussions and buy me a new one if i still want. Btw: The freeze-"bug" is one thing, and it does not more freeze when i only assign 4x per preset the EXP-pedal (but already starts to sometimes not function fully in all blocks). As i described above, i wanted to conter-check what the Floor makes in the same constellation. So i copied&pasted this 4Wah-preset into the Floor, connected the MIDI-cabel there, the general EXP-pedal-switching when the Floor starts is EXP2, so i simply do not touch the pedal there and thus EXP1 is then (because on the general CC#1) automatically driven via MIDI by the LT. Long speach short meaning: With 4 Wahs, it functioned. I thought: Has double DSP, add more WAHs. Did that and with 6 it started, with 7 it showed clearly too the bug in three of the seven WAHs (if it functions with you, you must then in HX-Edit click on the next wah to see its parameters and if the assigned ones move correctly, and if yes, then click on the next Wah-block and check the parameters, and so on - if with all seven in the Floor, or all 4 in the HX, it functions correctly, then i really understand nothing more (because i did use both LTs for to send the MIDI-command, and it does the same with both LTs, so i thought: it's not the LTs). ...My diagnose: The DSP of the the MIDI-command receiving unit has something to do with the prob. There's a limit for the quantity of assignments of an EXP-pedal in 1 preset when driven via MIDI, in the Floor it's the double of assignments per preset you can make - doubleDSP-. Then i wanted to look how much WAHs i can assign without this bug when i use the onboard-EXP-pedal (of the Floor for the MultiWAHpreset in the Floor). With nine i stopped adding, because it functioned perfectly (position AND level assigned) -- what makes me suppose that with an external pedal, this bug will too not appear. Then it's a MIDI-problem and really, this surpasses my technical horizon. (Post- edit) Aaah, and, "1db range, whatever" (+-0.5db) ... You hit my artists' heart'n soul, sniff, my pride. Of couuuurse this was not the original setting, which was individual for any WAH, well elaborated. But with the bug, and testing, as idiot and beginner, i erased and restored,, loaded completely new, ....and at the end, i knew it makes no sense to adjust the WAH-parameters individually every time with the values i had stored somewhere, but simply put +-0.5 db, was rapid and enough for to see what happens. And as beginner in that sim-technology, i am fascinated by the possibility that one can run a WAH parameter the reverse way, and it's an important knowledge, and i must internalize that so that it becomes ingrained. LOL, i think IT IS ingrained now, assigned it at least 40x this way and have digged the trick forever. Sorry for the work you had with that... 2jP IR_ 2GbDbCb.hlxWahWah.hlx

Tried to load both presets, the one into the LT (no problems), the other into the HX: it opens in HX Edit, but does not seem to load correctly into the unit. Tried to go in HX-Edit-> file-> save preset, pops up a window saying, ' Timeout waiting for response (code 8212) '. Googled for the code, found a thread in this forum, where a guy named rd2rk said You see me grin. I thus made a backup & restored fr. there, no success, your preset does not load correctly into the HX. It appears in the general preset-list, but when i want to open it, it says i must make my presets within the HX (not via HX-Edit), "Press big knob to open model list". When i push the BigMac knob (global settings) and then on Signal flow, i can see it's there, and when i then move to a block and click on the Action-button, i can see the first 3 of its parameters and that position moves when i move the pedal. But i can even not access all parameters of a block. Is that a general behavior from the HX, or is that a bug, or have i made some setting-fault (what i do not believe)? Stupidly, when i got the unit, i did not try it in the update-grade it arrived, but made directly the upgrade to 3.11. And from the begin on it was this way that i could not load the presets fr. HX-Edit into the HX-unit, but i had to make the presets in the HX-Effects-unit, then to put it off, again on, and then it loaded into HX-Edit and then i could tweak them there. It feels wrong, because with LT and Floor, it was always the other way around, i made the presets in HX-Edit, and they automatically appear in the unit. But i read in the forum now that many people had this problem with Stomp and HXFXs after upgrade 2.6, and then 2.9. A solution i did not find now and i have not the nerves tonight to dig hours for a solution of that prob. You see me laughing. I am the beginner in MIDI, so you may be right that i do something wrong here. However, the parameters in the blocks react, and i have no external pedal. It runs via MIDI. After studying your two presets that i can well see in HX-Edit, i came to the conclusion that the difference between my and your midi-command for the EXP-pedal is in the CC#. You use CC#19, i use CC#1, which is the global channel. CC# 1, 2, and 3 do not appear in the individual CC#-channel choices, it starts with CC#4. CC#1,2,and 3 are general, and reserved for EXP1,2 and 3 - as far as me idiot has understood that -. So you go in your Floor or LT, open the command center, and assign your EXP1 to CC#1. That's all, automatically in the HXFXs then, EXP1 is driven by this MIDI-commando. And you assign your parameter to EXP1, and not to a special "non-general" CC#. If whyever you want your EXP2 to drive the parameters in the HXFXs, you set in the Floor in global commands the CC# on CC#2. It's reserved for that. And then you can assign position of your WAH to EXP2 and it's driven by MIDI. However: I went then and made a preset like yours and assigned there the position and level to CC#19. Appears the same bug, position&level start to stutter (in two of the 4 Wahs) and do not more move regularly to 0 or to 100, but somewhere inbetween, 30 to 70, then 46 to 65, and so on. If the unit will freeze, i did not try until know. And a huge hug for your work.

And another finding: When using this mentioned 7Wah-preset in the Floor and using its own inbuild EXP1-pedal, then none of the "bugs" appears. I could even load two more WAHs (with nine WAHs, i stopped) and position and level still worked well ----- what makes me suppose that with an external EXP-pedal connected to the HX-Effects, probably one can run at least 4 WAHs in one preset with pos.&level assigned to it -. When i'll get the M-Audio EXP-pedal, i'll test that and report here If it really is so, then there is a MIDI-capacity-limit for that application (but do not ask me the technical background for it, as already stated 5x, i am totally ignorant in that matter). :) Good morning rd2rk (and all others too supposedly), i hope you slept well and that your machines do still work well (really, my deepest respect that you sacrifice the longuevity of your equipment for to simulate other people's problems; i hope line 6 / Yamaha pays you well for the work here, or at least, that they give you the equipment cheaper, or at least, that they repair them in case of fails for free. If not, then i feel pretty ashamed, and helpless how to thank you more than with cheap words that do not repair nor replace nothing). Now it's me that's going to sleep; good night.

And last counter-check: I copied this preset (of pic 01) into the Floor (connected via MIDI to the LT and its EXP1-pedal) and looked what happened: All four WAHS with position AND level assigned to EXP1 worked correctly. I had to add three more WAHs to that preset (7 in total), of course with pos. and level assigned to EXP1, for to provoke that position and level were not more reacting correctly. That is pretty proportional to the HX, which shall only have half DSP-power. So i assume now that this preset, or more exactly, the quantity of EXP1-pedal-assignments in one preset, is pushing the Helixes to their DSP-limits. Perhaps it does that only with this MIDI-connection, and with a true external EXP-pedal, connected to the EXP-pedal entry, it would not do that. When i'll have got the ext.EXP-pedal i ordered, i will too test that (and give a report here) -- if it does only this effect with MIDI, then MIDI is less usefull for that application and one should better buy a true external pedal and connect it with the 6.3''-jack to the mattering entry However: Now that i (believe to) know the cause (DSP-limit or RAM-limit or "MIDI-workcapacity"-limit), it is not more that drama, because i created this "Multi-Wah"-preset only for to test the different WAHs and learn them. :) For to play, i do not need two WAHs in a preset, much less four or seven. ----

Thank you very much, ...and sweet dreams. "Attach your presets" - thank you Sir, me stupid idiot. Arrgh, only excuse i have is that i am too old, did not grew up with computers, have not internalized all possibilities. Have you assigned too the Level-prmtr. of all 4 WAH-blocks to EXP1 like in the following pic? With that assignment to Position (Bypass controller assign->Position, 0-100%) AND to Level (Bypass controller assign->Level, min:+0.5db, max -0.5db) in all 4 Wah-blocks, when moving the pedal calmly and regularly from totally up to totally down and again totally up (..), position of all 4 Wah-blocks is not more reacting correctly, but moves only to 77% and back to 34%, the next time it moves up to only 68% (instead of 100%) and down only to 44% (instead of 0%), (etc), and now that i looked very exactly, i saw that too the Level is not more reacting properly, in two WAH-blocks yes, in the two others it did even not move. I made a video of it, but alas with 309MB, i cannot upload it here. If you tell me how i can pass you the video, you could see the dis-function yourself. In this video, after the presentation of that bug, i erase then the assignment to Level (see the pic below) in all four Wah-blocks, and position functions then properly again, from 0-100, in synchronicity with the pedal-movements. However, here at least the pic without the level-assignments: Pic02: Now, the position works properly, and the HX does not more freeze (at least the last 6x 45min). It was the first time i re-assigned the level to EXP1, and i was curious if all bugs re-appear, and they did (apart of the freeze, but i did not spend now 45min with that for to see this bug. I know it will happen sooner or later. And meanwhile i am pretty sure it does not more freeze with this setting of pic2). But i went aware that even with only the (4) assignments to position (of all 4 Wahs), position did sometimes show the bug of not fully going to 0 and 100. I had even to erase of 1 Wah the position-assigment in order to make it properly function with the 3 remnant Wahs. In consequence, i tried two things more: To erase from that preset all dist-pedals and both FXloops: Nope, still the 4 Wahs showed disfunctionality (with position AND Level assigned to EXP1). I had to erase even two WAH-blocks so that the remnant two reacted properly in Level and Position to the EXP-pedal-movements. For to exclude then possible defects of the pedal, i then connected my Floor (instead of the LT) and assigned its EXP1-pedal, and it did the same effect, no difference. And for to exclude the cable as cause, i changed for a shorter MIDI-cable, and too this didn't change the effect. Mattering global settings of all units: The EXP-pedals are set to global, and in the global MIDI-settings (of all units), all parameters are set to off, apart of MIDIbase channel which is set to 1: Wrong commandos are excluded. So the "fault" is IMO 100% sure in the HX. Or it's defect, or i reach with this preset the limit of its RAM or DSP-power (technical ignorant's diagnose).

I try my best (English is not my native language) I beg you (and all readers) for pardon for the mess. The difficulty here that may confuse you is that in the course of the thread, i entered a second problem (would perhaps better have done that in an own thread). However, you must separate them. The first problem has technically nothing to do with the second one and it is paused for the moment, because after the recommendations i got here, i ordered finally a simple external EXP-pedal and still i do not have it (for to try then the thingy with the Y-cable; ...if this thingy shouldn't function, the next step will be to buy a special external EXP-pedal, with two potentiometers and dual output). The second problem that chronologically i encountered then (and introduced then here) has nothing to do with the first problem and does not require two LTs or Floors. ----------------------------------------------------------- If you want to simulate my case, the hardware you need is 1 big Helix with inbuild EXP-pedal (thus LT or Floor), 1 HXFXs, and a one-way-MIDI-cable. None of both units is connected to a computer (no USB). (edit: both units upgraded to 3.11) You'll have to drive with the EXP-pedal of the big Helix (plus the EXP-pedal-footknob) the WAHs that you installed in the HXFXs-presets. [[[[in that matter a remark: As i was recommended, there is no other way than by MIDI --- i had asked in another thread if one can use CV-out for that, but was told not to do it, but to use MIDI, and this way, i entered the universe of MIDI - i am beginner in that matter and have thus many stupid-appearing beginner-problems; yes, i try to find the answers myself by reading much on that topic, however, i am not always understanding anything nor always finding the answer to a specific problem, and then i ask in the different forums that exist -]]]] For to simulate my case, you'll need to add four presets in the HXFXs (edit: the factory presets, i did not touch): Preset 1: One WAH (bypass assigned to the EXP-pedal-footknob of the LT/Floor). Then 6 dist-pedal-sims (bypass assigned to the 6 footswitches of the HXFXs). And 2 send-return. Preset 2: Item, only other models. Preset 3: Four WAHs (bypass assigned to 4 footswitches), 2 dist-pedal-sims (bypass assigned to the remnant two footswitches), 2 send/return Preset 4: One looper. Since it is a brandnew HXFXs-unit, i had not the time to create more presets. Connect MIDI-out of the LT/Floor to MIDI-in of the HXFXs and assign then the EXP1-pedal of the LT/Floor to Position (0-100%) and to Level (min+0.5db, max-0.5db) of all WAH-sims in these presets of the HXFXs. In total, you'll have 12 times to assign EXP1, 8x alone in preset 3 with the four WAHs. At this point, my HXFXs starts to disfunction (and too to freeze from to time). For to have better control of the parameters and easier workflow, i connected now the HXFXs to a laptop & HX-Edit and looked what happened there. I saw then that when i run preset#3 (with the 4 WAHs), the Position-parameter of all WAHs is not reacting correctly (perhaps the Level-parameter too, but the space fr. -0.5db to +0.5db is not big enough for to recognize if it moves correctly): When moving up&down regularly the EXP1pedal (from zero to 100 and back), the position-parameter of the 4 WAH-blocks react only limited, fr. initially 100% to 35% (instead to 0%), and back from 35% then not to the full 100%, but only to 72%, and in the next movement, it did not return to 35% but to 27%, and the next upwards movement then to 75 or 89, but not to the full 100%. [edit: independent if bypass on or off; did that too when all 4 WAH-bypasses on off] Switching then to the presets with 1 Wah-pedal only, anything functions perfectly, position and level do what they shall do. Back to the WAH-test-preset (preset#3): After erasing all 4 EXP1-assignments to the level-parameter, the position-parameter worked again properly. Said shortly: With 8 EXP1-assignments in that preset, the position-parameter started not more to function correctly. With only 4 assignments (level-assignments erased), it functions. And strange, unexpected beside-effect: Too, the HXFXs does not more freeze. At least until now, and this means 6x 45 minutes. So i start slowly to believe that i really found with that the cause for the freezing. And with my admittedly very limited knowledge about computer-technology (and as far as i see it, the Helix-units are a type of computer), i would say that this cause calls "RAM-limit reached (or even passed)" and in continuation, the HXFXs froze then. Maybe it's not the RAM, but the DSP - as i said, i am totally ignorant on computer-technology -. Perhaps the DSP contains the RAM, i do not know that. In any case, when i liberated the HXFXs from 4 EXP1-assignments, a) the position-parameter of the 4 WAH-blocks in preset#3 started to work again correctly, and b) since, the HXFXs does not more freeze. What is the more very strange (and the cause why i mentioned all 4 presets), is that it froze during the use of all 3 presets with WAH, it froze too when i used for example preset1, where EXP1 is only assigned two times. I would say (but i am ignorant in that matter) that a preset that is not running is consuming zero power of the unit, however: The HXFXs froze during the use of any preset and why should a change in one preset influence the behavior of the HX in all presets? (I have not the answer to that, and) That is the cause i mentioned so detailedly all 4 presets. Last detail: For to have the EXP-pedal of the big Helix-unit always in EXP1-mode, i inserted a dummy-jack to the entry of ext.Exp2-pedal of this Hlx-unit. Edit: I did not touch the factory-presets in the HXFXs, add only mine. And i made the upgrade to 3.11. Edit: If your HXFXs is functioning without problems [nor showing disfunctionality of the position-parameters when in preset#3 (with the 4 WAHs) EXP1 is assigned 8x, nor that it is freezing then (sometimes it froze only after 45min, but mostly in the first 5-7min)], then my HXFXs-unit is broken and i will return it, it's still within the first 30 days. ...But if it shows the same symptoms, then the HXFXs is IMO a little sub-capacitated (respectively overpriced, relative to the LT) and i'll ponder to return or to sell it and buy me a LT instead [...but that would then (in the case it's a general symptom, what we still do not know) not be meant as a fundamental critique at the HXFXs (!); ..it's only a remark made from the point of view of my personal requirements & demands that in that case surpass the capacities of that unit. But IMHO the Helixes are all ok & absolutely worth their money and if the HX should correctly be 50 or 75 bucks cheaper relative to the LT is really not the point for to reject it, it's too a good unit and absolutely worth the money it costs - 200 pedals are far - faaaaaaaaar - more expensive...].

That is the point. Actually, i play less guitar than i am occupied with installing and learning that simulator-technology. Never ever i had the intention to enter the universe of soundengeneers (MIDI, DAW, computers and all that stuff; i must now even buy a new computer because mine is too old for nowadays DAWs and Helix Native). If somebody would have told me that before i ever bought a Helix, i would now have at least 200 hours more on the guitar-time clock. :) Too late, i ate from that apple... ;)

@all: *heartily laughing when i saw the pic with the hundred pedals. I have it less with pedals, i am more the guy with the hundred amps. Ok, not hundred, but more than one. When i play real amps, i bridge three (tres, drei, troi, 3) 100W-Plexis with their double-cabs (makes 24 speakers), or alternatively, for to get a more modern sound, instead of the 3rd Plexi, i use a DSL (with its own special doube-cab). And with that private "wall of doom", i do not use many pedals (i have three, among them a WAH, but only active <5 % of the time i play, as good as never, If at all, the Wah, and then one fuzzy overdrive with it, i have the jackhammer II for that, in overdrive, set very slight). I do not discuss with people that use one Plexi with one simple (half double) cab the question if '3 Plexis with their 3 double-cabs' makes sense, really, i do not ------- but i heartily smile reading that Hendrix, when a famous sound-engineer in the studio insisted to turn down his three Plexis to 5 (they were always on 11) or to disconnect at least the top-cabs of that Marshall-battery, got a heavy tantrum. And i smile when i see the person with the one Plexi and the "half-cab" using as good as always several pedals. Well, when i bought my first Helix (a Floor), i was an adult (!) and i bought it as a toy (!). Didn't need it. But please, where do you have the opportunity to test at home tranquilly 80 amps and 200 pedals? For 1500$ only. Well, add other 1500 for the (active) FRFRspeakers, or 3000. Still cheaper than the originals. Apart of that i do not have the space for to install 80 amps, 80 double-cabs, and 200 pedals. See, my case is more like somebody that has the Top-Ferrari and buys - purely for to play and see - a simulator where he can drive the sims of 200 fast cars in different constellations. Just for fun. And because it is fun, he buys then more screens, more computerpower, a 3D-movement-unit, a gasoline- and tyre-smell-unit, etc. Still he is convinced to have the best in real form, his Top-Ferrari. However, he likes it too to drive the Viper and the Porsche and the Lambo (etc) and too his own Ferrari in his simulator. Tell me how you can simulate 3 bridged Plexis with 6 cabs and their special micro-arrangements with the Helixes. *headshake*: Not possible with one Helix-unit. You need two. And yes, you need also the speaker-battery, 6 real double-cabs are 24 speakers. :) Let that be my problem. So far for that. Back to the topic of this thread im my next comment, i beg for some patience, it's not done in 5 minutes - btw: i know you sacrifice the same reading my stuff and trying to help me, and i thank you for that. Be assured that there are topics where i am specialist, and yes, there, i do often sacrifice entire hours helping others for free.

:) Not sure, i still do it snapshot by snapshot and command by command. Only when there's no special snapshot, i paste all commands at once. If somebody can explain me why MIDI-commands cannot be made globally, i would be happy. Back to the precedent issue. It seems that i could resolve the freezing-prob of the HX. Seems it is an exhaustion-prob of the HX (not enough RAM or so - i am not a computer-specialist -). I liberated one preset from some EXP1-assignments and then it stopped to freeze - until now at least (i played since let's say 5x 45min and no more probs). But it's all partially contradictuous to me and i am too not sure if it's a general HX-effects-problem or if my HX is defect. So i decided to explain here in all details what i did (from the point on of your councils & proposals): What matters the MIDI-loop-question caused by wrong global MIDI-settings or wrong cabling (btw: I found meanwhile the "unofficial Helix MIDI guide", where this MIDI-loop is described): MIDIcable1 goes fr. LT1 to LT2 ------- EXP2 fr.LT1 is assigned to the gain-blocks at the end of any preset of LT1 and LT2. MIDIcable2 goes fr. LT2 to HX ------- EXP1 fr. LT2 is assigned to the WAH-pedals in the presets of the HX. Both cables are simple (not double-cables, send&return), one measures 1m50, the other 2m50. All EXP-pedal-settings in any unit are global. The MIDI-settings at the moment of your idea to check a possible MIDI-loop: MIDI/Tempo LT1 LT2 HX MIDIbaseCh 1 1 1 MIDI thru off off off receive MIDIclock off off ------ send MIDIclock off off ------ Tempo select Global Global Preset Global BPM 120 120 120 MIDI over USB off off ------ MIDI PC send off MIDI&USB ------ MIDI PC receive off MIDI&USB ------ Duplicate PC send off MIDI&USB ------ RxMidiclock ------ ------ off TxMIDIclock ------ ------ both (MIDI&USB) The HX is mostly not connected via USB because i can only connect two Hlx-units to my laptop and for to have rapid access to my main-presets with the amps, which are in the two LTs, those are usually connected via USB to the laptop & HX-Edit. However: I set then in the LT2 the MIDI over USB, PCsend and PC receive to off, and too in the HX the TxMIDIclock. No success: Still the HX froze, sometimes after 2min, sometimes after 5, sometimes after 45min (during the use of any of the 3 presets i have there in the HX - thus not preset-depending -). So, the HX still froze. For to countercheck, i installed then the Wah-presets from the HX on a Hlx.Floor, pulled the MIDIcable from the HX and inserted that end to the Floor (all MIDIsettings like LT1) and it functioned perfectly, the Floor did not freeze. What was a first indication that the cable may not be the cause. I reconnected the HX. For to be sure, i changed the cable to the HX for the shorter one. Functioned 1x 30min plus 1x 45min. Don't ask me why. Then i wanted to change back to the long cable (which functioned perfectly between both LTs, as also when connected to the Floor). But before, i started to change some settings in the WAH-blocks because i didn't like the Bypass-setting to EXP-pedal-position that i had made for two of the three presets ---- 2presets are normal in the meaning that there is every time 1Wah, 1Eq, 5 dist-pedals and two send-return, whereas the third preset is a special WAH-test preset with 4 WAH-pedals, 2 dist-pedals and 2 send-return (these details will become important later, and if somebody will make a simulation of my case, these are the presets). There is a 4th preset, only with a looper. I assigned the Bypass via MIDI to the EXP-Pedal footknob of the LT2 (base ch1, CC#4), the pedal there is the WAH-pedal for the HX. Put a dummy-jack in the EXP2-entry of LT2 in a way the EXP-pedal there is always in the EXP1-mode [beside remark: Alas that had no effect on the initial problem (that the gainblock of a new preset in LT2 is not immediately adapting to the real EXP-pedal position of LT1); i had had the slight hope this dummy-jack would somehow mirror the command in a way the LT believes it's a real external EXP-pedal, but it made no difference]. Then, before to reconnect the long MIDI-cable to the HX, i went aware that in the third preset (with the 4 Wahs), the position (of the pedal) did not react correctly: When i moved the EXPpedal up & down, the blocks reacted only from 100% to 35% (instead to 0%), and back from 35 not to the full 100%, but to 78% only. And the next time only to 52 and 87, etc. It did not work from 0 to 100. ...I switched back to the presets with 1 Wah-pedal only: Strangely, there anything functioned perfectly -- thus this was not due to the cable nor to the EXP-pedal-potentiometer. So i returned to the "Multi-Wah"-preset: Any Wah there had&has the bypass assigned to a footswitch of the HX. And in any WAH-block, EXP1 is assigned to 2 parameters, position (0-100%) and level (min +0,5db, max -0,5db). That says that in this preset with 4 WAH-pedals, EXP1 was effectively assigned 8x (when i add the assignments in the 2 other presets, it's 4 assignments more, so 12. I would say as technical ignorant that a preset that is not running is consuming zero power of the unit, however, the HX froze in any preset and why should a change in one preset influence the behavior of the HX in all presets?). Of course, i used only one Wah-block at the time (gives me the idea what sounds could be produced with 2 Wah-pedals simultaneously, perhaps one running the reverse way - will check that one day -). However: After erasing the EXP1-assignments for level, the position worked again properly. That says: With 8 assignments, the position started not more to function. With 4 assignments, it functions. I changed back to the long MIDI-cable and what shall i say: It functions since, does not more freeze. I played perhaps 5x 45 min since. I start to trust it. If after 10h hours, it still has not frozen, then i would say that this really was the cause (too much stuff assigned to EXP1). Not enough computer-power (RAM, DSP or whatever) ??? Or is there the defect of my new HX? Has somebody a HX and can test (simulate) that?

Ok, thank you -- i ordered thus a simple, cheap M-Audio EXP-pedal. An Y-cable, i can make myself with a female adapter, in a way i will not have to damage the fixed cable of the M-Audio. Let's see. Should arrive soon. If it functions with the Y, and if i am then lucky, then (with the external pedal) both presets' gainblocks will always directly adapt to the actual position of this pedal. Would be one prob resolved. But sad then that with the inbuild pedals, it does not function. I am still testing, the problem with the HX freezing is not resolved. All settings were ok (anything was off), MIDI through too (off on all units). And no, i had no loop, i have two single MIDI-cables, one is going from LT1 to LT2, the other from LT2 to HX. The thing is that sometimes it freezes in 5 minutes, and sometimes it needs more than 45 min for to freeze. And sometimes it does not freeze in an hour. Strange. I have the more a Hlx.Floor and put the Wah there and simply disconnected the MIDI-cable from the HX and connected the Floor to it, same MIDI-settings, and anything functioned beautifully, two or three times for 45 min. The Floor is not freezing. Then today i changed the MIDI-cables, the one that connected to the HX is 1 meter longer. And damn, since i did that, the HX is not more freezing. One should in continuation assume that the cable was broken (a new Roland Black series, 2m50cm), but this cable connects now both LTs and anything there works perfect. Well, i am not convinced that the cable was the problem, but if the next 5-10 days, the HX will not more freeze with the shorter cable, then this problem seems to be solved, but i would then not understand how a cable can function here and there not.

Oupps - i apologize. Had not realized that. Stupid, or in that case, blind me. I have erased the mattering wrong remark. For the case i find one, promised. So, thank you then from heart, rd2rk, for your detailed answer and help. I had read that, but i asked me how you did that without to use two units (may that be the HX-stomp and the HX-effect), but you mentioned nothing, so i thought, '"perhaps he did that with one Floor and Hlx Native" and didn't ask for precision. So now my question in that matter (and btw thank you very much for the time to simulate my case): How did you connect one (presumably simple - with one out -) EXP-pedal to two presets? Two presets, to me, signifies two Helix-units. However: An ext. EXP-pedal - very probably the EH Dual - is on my list, but this list is already somewhat longer, contains among other also a new PC for the DAW and Native that do not run on my Celeron Laptop, and my moneybag has a cold, i just bought an LT and a HX... And i encountered last night a new problem with EXP-pedal and MIDI (seems that me and MIDI will not become friends): I try to drive the Wahs in a HX-Effects with the EXP1 of one of the LTs (of LT2 for to be precise): It functions for a moment and then suddenly the HX is blocked, frozen, nothing is functioning. I have to reboot. Today, it happened again, and since it's a brandnew unit, i have to resolve rapidly if i do a setting-fault, if the LT has a bug, if the MIDI - cable is defectuous, or if the HX is broken - then i would immediately return it -. MIDIchannel base (but i tried too with 6, same effect), CC1, min1 max 127 It's a preset with 8 blocks, the Wah is not assigned to a footswitch, but i set it in a way so that it activates when the pedal is pushed down(Bypass set to EXP1 and position turned to zero) . That functions for some minutes and then suddenly, the HX is frozen (but the guitarsignal passes). At the end, i pulled the MIDI-cable and the next half an hour, the HX run like it should. Any idea?

As creator and in some kind owner of this thread here: What matters the initial topic, the fizziness-topic is off-topic. It (the fizziness) is not my problem and i admit to have forgotten to mention that it is not the only cause why i use two Helix-units parallely, the other cause is that i can create this way far more sophisticated presets. Before to discuss this topic here [[[[what effectively would better be done in an own thread dedicated to it, however, (@phil_m & rd2rk) i will ponder if i will enter into the issue later here in this thread since it seems to me that in this forum here, private conversations with other users are not possible (or i was only too blind / too stupid to discover the mattering link); but it's not that i would have any questions on that topic, thus i do not require that conversation, and if you too not, then we do not need it - the tone of voice your comments seem to have make me unsure to estimate what are your needs and intentions in that matter - )]]]], i would prefer that the comments here are in first line helping me to get the answer to my questions (which are, as said, the topic of this thread here). For to bring back on the road this already deviated thread, permit me to resume them: I look for a way to drive the final gain-blocks of two parallel Helixes simultaneously with one EXP-pedal. And of course, i would like to be able to use the inbuild EXP-pedals for that. Alas, the MIDI-solution i found (see above for the settings) is only apllying per preset, not globally. That means that when i change the preset of the 2nd Helix, the gain-block there is not at the vol-level the EXP-pedal fr. Hlx.1 is actually indicating, but at the volume-level it was saved with; ...i must move the exp-pedal so that the gain-block of the new preset of the 2nd Helix reacts to it and adjusts to the vol of the first Hlx. Seems that the MIDI-command i use is only working per preset, and not generally (or "globally"). I don't know if there is a MIDI-command in that matter or a global setting that would make effect the position of the Exp-pedal immeditaly - too when i am changing the presets -. I was too wondering if the CV-out could be used for that goal. Another possibility would be an external EXP-pedal to which i connect both Helix-units, but as phil_m already mentioned, it is not sure that this functions, it would have to be tested by the trial&error-method. The EXP-pedal he proposed is really very expensive, too expensive for an experiment with unknown outcome, so i looked for a cheaper alternative, found the EH Dual ( https://www.ehx.com/products/dual-expression-pedal/) and asked Phil_m and anybody else to check if this one has the same features than the (fr. phil_m proposed) ME SP25L-Pro Aero. And last but not least, i had too asked if a simple EXP-pedal with one out, connected with an Y-cable to both Helix-units, wouldn't do the thing (or if then some electrical values change in a way that this is surely not functioning) -- i am not a specialist in electric matters, so i ask. (@phil_m & rd2rk: Sorry for the edit. @ all: Sorry for the mess /\ )

Yes, EXP2 to global (forgot to mention that). And i think you got it right. In any case, your description "the MIDI Value of the assigned parameter will always revert to the SAVED Value." is what happens. For an experiment with unknown outcome, 200$ (for the ME SP25L-Pro Aero) is too much money, for me at least. Thus i looked for cheaper alternatives and discovered from ElectroHarmonix the Dual-pedal ( https://www.ehx.com/products/dual-expression-pedal/). ...Do you think it's an alternative to the mentioned ME? As far as i can judge (but i am relatively ignorant in that matter), it seems to have the required features and it's less than half of the ME's price. Wouldn't a normal EXP-pedal for 30-40$ with one out plus Y-cable work? Or would this represent changed electrical values and surely not function? Why 2 Helixes parallely? For to get rid of the "fizziness" of the Helix-sound.

It's the first time i did something with MIDI. Maybe i did something wrong. The situation: Running parallely 2 Helix LT. All presets have always as final block a gain-block to which EXP2 is assigned for vol-control (+6db -> +12db). Problem: I want to drive the gain-blocks in both Helixes parallely, with one Exp-pedal. Solution(trial 1): Did it via MIDI, but it does not work to my satisfaction; i describe what i did: 1. Midi-cable (Helix1 MIDI-out -> Helix2 MIDI-in). 2. Assigning in every preset of both Helixes to the mattering final gain-block the EXP2-pedal. 3. HX-Edit, for Helix1: Window -> CommandCenter: Set for the EXP2 the MIDIchannel on Base, CC on 2, min-value on 1, and max-value on 127. Result: The gain-block of Helix2 is reacting as wished -- i can drive with the EXP2-pedal of Helix1 the gain-block of both Helixes parallely, but: When i change now in the Helix2 the preset, the gain-block there is not directly in the actual position of the EXP2-pedal of Helix1; for instance: The gainblock of the preset in Helix1 may then work with +6db and the of Helix2 with+12db. I have first to move the EXP2-pedal of Helix1 up (or down), then the gain-block in Helix2 reacts to this movement and in continuation equalizes to the in the Helix1. This disturbs completely while playing. Question: Is there any trick so that when i change the preset in Helix2, the gain-block there is immediately in the actual real position of the EXP2-pedal of the Helix1 (i.e. other MIDIchannel-setting, other CC, and/or other value parameters, or a special setting in 'global settings'->MIDI/Tempo) ? If there is no trick, then can i use CV-out for to achieve what i want? And if that is no option, can i buy an external EXP-pedal with two outs (or an Y-cable) and connect it to both Helixes? With that one, i think, both gain-blocks would always adjust immediately to its actual, real position. However, it would be an expensive solution. EDIT , 12/12/2021: This thread became finally very long, there were appearing more problems of which some were solved and some have to wait for an answer because i have to wait for to get some parts (extrnl.EXP-pedal). So i will here make an interim-report: Problem1: That's the above described one. That the same (gain)block in the next preset does not automatically & immediately adjust to the actual position of the via MIDI connected EXP-pedal of another Hlx-unit is due to the fact that MIDI-commands in a Helix work per preset, and thus always load with the values they were saved with (TY rd2rk for that one). Apart of that detail, it works perfectly. Post-Edit 12/24/2021 : Got the extrn. pedal (simple one fr. M-Audio), connected it with Y-cable to both units, and perfect: i can change the presets in both units and the same (gain)block in the next preset is automatically & immediately adjusted to the actual position of the pedal. For CV-Out, see Problem3, at the end (i tried it in another combination of units, which may be appliable for the described constellation here). Problem2: I got then another problem, for which i should have better opened an own thread. Connecting a HX-Effects (abrrvtn: HXFXs) to a Helix LT (or Floor) and driving all blocks in the HXFXs that need an EXP-pedal with the onboard-pedal of the big Helix-unit, via MIDI. Appeared the strange effect that from a certain quantity of EXP1-pedal assignments in one preset (of the HXFXs), the parameters in some of the blocks started not more to correspond correctly to the movements of the EXP-pedal. This started with 3-4 assignments, with 8 assignments it is superobvious and also the HXFXs then starts to freeze sometimes. Still i wait for technical explanations, however, practically, we have then to reduce the assignments to two or three, what should for normal presets be sufficiant. This is only valid for MIDI-driven EXp1-pedal assignment! It may well be that when you use an external pedal, this limitation will not appear and that you can then assign this pedal 7 or 8x per preset, or even more. When i will get the extrn. pedal, i will try that and report it here (in this post). Post-Edit 12/24/2021: With the extrn pedal, i can with it run in the HXFXs the 4 Wahs with their 2 assignments, they react all 4 correctly. Problem3: This is again for HXFXs (and HX Stomp perhaps): Seems that Line 6 makes all sims with default settings adapted to the capacities of the Floor & LT and in consequence all blocks that need an EXP-pedal have their Bypass by default assigned to the EXP1-pedal. Now, when one tries to use via MIDI the EXP-pedal of a Floor or LT for to drive such a block in the HXFXs, (s)he will have the surprise that when creating a preset in HX-Edit for the HXFXs, and choosing such a block with EXP-pedal assignment, this one will not appear in the scribblestrips & the LED-ring stays dark. The preset looks like that: and the unit: The solution is to open the Bypass assignment-window (right side of the edit) and to replace the default-EXP1 assignment there to the mattering Footswitch(es), in my case here FS2, 4 and 6. ---------------------------------------- CV-out: I am still not that clear about this possibility: I was adviced by some people here (in another thread on CV-out) not to do it. However, i found too in the >>The “Unofficial” Helix MIDI Guide<< following tip: In a non-english Floor-manual (the german one), it was precised that the CV-out is foreseen to drive analogue devices. The HXFXs is a digital device. In the original english manuals, this limitation is not mentioned (at least i did not encounter it). Now, the 1/4jack-entry of an external Pedal, too in a digital device, is analogue. However: I tried it rapidly for to drive the three blocks in the above preset (foto): Had to turn down in the Floor the CV-value parameter in the CommandCenter to 36 (i believe to remember) and then the sweeping-angle of the pedal was adjusted correctly and the driven blocks in the HXFXs did what they should. But: I had the impression all LED-rings and the scribble-strips started to "flicker", as if they would get changing voltages and in regard of the warning advices i had got, and that it is an "unofficial" guide, and that the german manual specified on analogue devices, i stopped with further trials. Basically, it functioned, but i do not know if the HXFXs or a Stomp would get dammaged. In case, better ask the line6 service if they allow/ recommand that application. I refrain from any responsibility here. Thanks to rd2rk and to datacommando. EDIT , 01/31/2022: Sad: line 6 service denied me after the first (welcome)reaction, although that i renewed my request several times. No more reaction until the ticket finally turned unvalid. Strange behavior. Perhaps the Pete there is rd2rk, this would explain me this behavior. If not, then i have no explanation. However: Thus i got no answer to the question if we can connect a HX-Effects to the CV-out of a Hlx.Floor. And too no answer to the question if the MIDI-overloading is normal; but in this matter, i read meanwhile that overloading MIDI can in case stress the receiving unit to the point of freezing, this would correspond to my experience here. So i would answer this question with yes, the HX-Effects can freeze because of too much MIDI-commands, more than three MIDI pedalfunction-commands per preset i wouldn't recommend. Meanwhile i bought a second ext. pedal for the HX-Effects and it did never more freeze (and too no dis-function, even not with my multi-Wah-test-preset).

Hi Phil I did as you recommended and yes, basically it functions. EXP2 of Helix1 is assigned to a gain-block, then i opened in HX-Edit Window->CommandCenter, and set for the EXP2 the MIDIchannel on Base, CC on 2, min-value on 1 and max-value on 127. The device is connected via MIDI-cable to a second Helix with, let's say, the same preset, and the gain-block there is reacting as wished -- i can drive with the EXP2-pedal of Helix1 the gain-block of both Helixes parallely. But when i change now in the second Helix the preset, the gain-block there is not directly in the actual position of the EXP-pedal of the first Helix, but i have first to move that one up or down so that the Gain-block in the second Helix reacts and equalizes to the in the Helix1. That disturbs while playing. Is there any trick so that the gain-block of the 2nd Helix is imediately in the position of the EXP2-pedal of the first Helix? If not, then i stand again at the beginning of my request how to drive them parallely. Perhaps then i must buy an external pedal with two out and drive the gain-blocks of both Helixes by an external pedal for to really never have differences in the equality of the volume, too when switching presets. Aunt Edit: But it's still better than the situation was before your hint.

Well, why - i described at least one cause; ...perhaps i should propose on ideascale to add a number behind the name for the case two identic devices are connected.

I have not understood how the 'user default' in the blocks' right-click-menu is effecting and how it works at all. I thought it's for to individualize blocks and being able to load them with personal setting-preferences, but nope, nada. Or i do not understand the thingy correctly or i do something wrong. Can somebody help me?

The one problem is: Gain-block with assigned EXP2. When i store this in favorites and load it from there, the EXP-pedal has disappeared. Second problem: Simple Vol-Block, special name (e.g. 'Vol +9db'), LED violet, 'snapshot bypass' set off. When i load it from favs, the name is not copied, the LED is lighting in "autocolour", not in violet, and the "snaphot bypass" is on instead off. I do not know if these are bugs, or if it makes a sense that the block is always loading with "snapshot bypass" set on. Or that the LED-colour is always on automatic. Or that the name i gave to this block is sometimes loaded and sometimes not. Because sometimes, one of the three things is loading (and two not). I really do not understand that. It does that with all three devices (LT, Floor and 2nd LT). I would really like that specially this "snapshot bypass" is surely off when i load a block. I tried to click "user default" before to store it as fav, no effect. Effectively, i have not discovered what this "user default" is good for and how it works. So, that would be the third problem in that matter

I have 3 devices of which 2 are Helix LTs. When i open HX Edit, two of the three opening windows call the same ("Helix LT"), what's absolutely not helpful (again&again i tweak the wrong LT because both windows look the same and i confuse them). I did not find out how to change the name of the device, for instance to call the one HelixLT1 and the other HelixLT2. Does somebody know the trick or is there no way?

Yeah, i got it later the same day; ...learning is never ending. Sad, there are some nice amps there that alas are not in the Helix.

Thank you. :) I did not know more on MIDI than how to write that word. Looked some videos on y-tube and read some articles and now know i will have to read some stuff more. But ok, i want for the moment only to drive the EXP-2 of the Helix2 with the EXP2 of the Helix1. So i bought a midi-cable and opened in Hlx.Edit of Helix1 the Command-Center and assigned there the EXP2. In the Helix2, eventually i did nothing. Functions, the mattering Vol-Block (to which EXP2 is assigned in both devices globally) in all the presets and all preset-lists of Helix2 reacts as wanted. Alas, in the moment i go in Helix1 then to another preset, the assigment is erased. It seems to me that the way i do, i do program the command-center only for a preset, but not globally. Is there no way to program the Command-Center globally??? Edit: Seems so. Thus again spending my hours with tweaking 1000 times the same. So many tweakings should be faisable globally or per preset-list. That's really an issue with the Helix. Alas i do not know enough about programming, but i cannot imagine there's no way to introduce this option, at least for Vol-blocks and for the output. And for the Command-center. Simply add a switch that says: Apply globally. Apply for this preset-list. Apply for this preset (specially with true parallel path-presets). Ok, phil_m, thanks for the hint, i use the fiirst time in my life MIDI. Was even able to assign footswitch-commandos, but it is every time a fight to get the right colours in the display (they're first grey instead of green or violet or whatever and it's a strange and at first impression unlogic procedure for to activate the assigned colour).

Not sure if i understood that correctly. If i use two Helixes (floor / lt) parallely, and want to drive the gain-blocks in both Helixes with one Exp-pedal, is it then possible to connect the CV-out of the one Helix to the EXP-pedal-in of the other Helix ? The EXP-pedal of the first Helix should then appear in the second Helix as EXP3, i suppose. And then, i could assign the gain-block of the second Helix to the EXP-pedal of the first Helix. Would be useful. Could then also assign blocks in a HX-Effects to the EXP-Pedal of a Helix-Floor this way. Possible?

Hi all I got this promotion-email a week ago and studied the model-packs, discovered several amp-sims i want and then i found a web-side saying that these model-packs are NOT for the Helix. Is that true? Must i now buy a pod go (or one of the other 8 indicated machines that i do basically not need) for to get these amp-sims or is there a way to get them for the Helix Rack/Floor?

Thanks for the video. That's a correct information (in the video): That manner with the 16 Ohm for stage-speakers is from the early days of loud rock, i.e. the use of Marshall 100Watters and their cabs as PA: With the then often very long speaker-cables, for to avoid a significant loudness-loss, it was better to use 16 Ohm. When the same speaker-cab is used and only the wiring inside changed for to adjust the speaker-impedance to the amp's output-impedance (as done in the video), then it is logic that the shorter the cables between amp&speakercabs are, the less audible difference will be perceivable. And with really short cables, the difference should be minimal, subtle, and at this low volume like in the video (mostly around 100db, +/- 5db) surely only technically measurable, because it's mainly only a slightly different impulse-response that most not in the audio-matter schooled ears will even not realize (specially not at this "relative bedroom-level" for Plexis). 16 Ohm is only interesting when the cables are that long that their own impedance surpasses 1 to 2 Ohm and the volume shall be 120 db and louder (100W Plexi-level). In that loudness-area, the guitarrist will "feel" it the most (and 16 Ohm will turn out to feel - respond - better). But that was not the volume they used in the video for their test. 100 db a 1Watt-tubeamp can easily reach and the volume in the video did not pass the 105 db. A Plexi is still sleeping at that volume (as the Greenbacks too).... IMHO: Really, i do not buy a Plexi for to play it on 3 or 4 with the eq on ~5 +/- 2. (Surely not a general rule, but) It may well be that the lower the volume, the more agradable (more complete, organic, or 'together' as they say in the video) a less high impedance sounds - that will depend the single amp's as too the single speaker's characteristics (!) and too the of the pickups, the entire combination -: At that low volume, the impulse-resistance or -strength isn't really a predominant audio-factor. So it may for example well be that an amp like the in the video used Matchless-combi (4 Ohm pre-installed by the brand) sounds better this way as long it is not fully cranked and when fully cranked (so-called 'british-setting'), it will turn out that not few guitarrists will prefer the 16 Ohm-wiring and -connection.
