  1. Hi, great idea, i wonder how you managed this But wich file to dowload? Perhaps i'm blind but i can't see one :(
  2. Switching off the crossover does'nt make a linear speaker or a instrument speaker out of a woofer ;) Subwoofer drivers are usually designed with other aims, so i think you will miss a lot of the high end and usually you will get a lot of coloration in the midrange. So just the opposite of FRFR.
  3. Shure? I think, there's a bit more behind ;) Often, an ideal acoustic cab is FRFR, and that's what's often used behind the Helix. Following yout theory, choosing "no cab" should get a sound wich tends to acoustic. But it doesn't. As i understand, an IR represents a complex impulse response of the first milliseconds of an acoustic signal. This response is containing informations about frequency response, attack, the first decay and phase. Even if intended to simulate a speaker response, it could (and i'll bet ist is) used to simulate a part of acoustic guitar characteristics. Simulations of other electric guitars should be possible to. The problem could be, that every pickup/circuit/cable has it's own frequency response defined by resonance frequency and Q. First you had to eliminate this to get a clean base, but you have to know these values of your pickup first. With this flat line, you could add characteristics of the desired guitar sound as (another) resonance frequency an Q, some attac and decay, where the decay is limited to some milliseconds. The main problem in doing this will be the unknown characteristic of your magnetic pickup.
  4. Hi, no real advice from my side but the same target. And i want it small and really really light. I think, a modern machine like the helix and usual speakers (wooden enclosure) is a bit like a F1 engine powering a tank ;) It works, but is it smart? So im planning and just starting to build powerd cabs for myself, but 12" as i don't belive that 10" stands for punch where 12" does not - don't see a physical relation in this therory. I'm going to a pair of 45 liters (inside) vented housings made from a XPS-carbon sandwich - weight about 2,0 kg each. Inside a 12" coax - first try with Emience Beta12CX + ASD1001, but i have a look onto the new FaitalPro 12HX30. Both coaxes are about 4.3 kg. Both deliver a reasonable Xmax for bass and PA use (not needed for guitar), both seem to be pretty linear FRFR with a DSP. OK - the Faitalpro wil probavly cost 4 times the Emi - we eill se if it's such better. Each unit will be powered by a Hypex PSC2.400 Module, delivering 2 chanels 400 W RMS (but "only" 500 W RMS togehter) with a powerful and fully configurable DSP. The module is 1.1 kg. So i'm at 7,4 kg for each 500W RMS 12" DSP-powered Coax and some grains for corners,cables and handle. The DSP tuned for FRFR should give me more than enough power and flexibility for guitar and bass at 15 kg and a small PA down to about 60 Hz. In case of emergency, t think about building an aditional 2x15" Sub in the same way but with a 1200W RMS Module for about 17 kg. That's the plan, the first compoments should arrive next week :) I just think that the Helix could match better such a construction than a ton of wood, but that's just opinion and taste ;) I got some ideas from the fractal forum, the talkbass forum, Xitone cabs, flitecabs, some expieriences with the building of my full carbon guitar. Plus some ideas from airplane construction, some composite-forums..... So the idea is perhaps not new but a way for me to get what i want when others does'nt sell it ;) And i'm not shure if there's a comparable concept on the market - i did'nt finde one. And i'll bet real carbon housings will look more cool than vinyl with a Helix :) And i want a orange glowing powerswitch on the front - nearly impossible to find on powered cabs and one of the first reasons to think about buildig it by myself.
  5. Alternativly, co could put a old sock (or a fresh one if you have) in the reflex port. No kidding - this could work for guitar use ;)
  6. behind all the technical details we will see in later hand on's, tests and comparisons, the headrush seems to be an pretty interesting thing. The touchscreen is one more detail to make Helix usability still better. About the sounds - we will see. But: Even if i would like some things different in the Helix - they defintivly spendet a lot of time, work and brain in the usability concept wich i've never seen before in a unit like this. Did'nt nobody notice that in the main aspects, the headrush seems just to copiey the Helix? I tend to support the inventors, not the copyshop people ;)

    Tuner

    Pehaps this discussion is a bit difficult cause we're talking about two different aspects? - tuner is jumpy in detail: Yes it is :) The more accurate the tuner ist, the more it's jumpy just because a guitar is jumpy and this is shown by the tuner ;). - tuner is jumpy in common: Sometimes - Yes. I feel that the global tracking of notes ist a bit nervous. It seems so me, that the helix reacts more sensible to any disorder of the base frequency and it gets more sensible the lower the input signal is. So sometimes it needs time to recognize the note and sometimes it looses the note as the signal gets weaker. A good software tuner for smartphone does indeed a better job by the build in microphone, so i use this for settig up an instrument. In both cases, some points help to get more stable values, where the helix tuner ist still more sensible to these points: - don't bend your neck while tuning! (at least not the guitars neck :D ) - carefully damping all other strings and even unused parts of the tuning string makes tuning more stable - Helix reacts extreme sensible to this point -more than other devices - Using the neck pickup helps a bit and even turning tone on the guitar (if available) down makes things better as it seems to reduce the signal as far as possible to the base frequency.

    Tuner

    How do you realize tuning with 0.1 ct accuracy? :o All my stringed instruments vary minimum 4 cent from attac to release, basses even more. I can withour effort change the tuning by 11 to 15 cent just by beding the neck a little bit, bass even more. With normal tuning heads, it's not possible to me to adjust with more than 1 cent accuracy. Even setting up the bridge or (compensed) saddle for intonation does'nt require this precision. And i work a lot with this things. The only instrument i have with a bit more stable behaviour is my full cabon electric (called "tank towing bar" by some people ;) ) and even for this, 1 cent is quite enough. At guitar E 82.4 Hz, 0,1 Cent is about 0,0049 Hz. Shure you need this? We talk about a more or less flexible instrument where strings vary their tension while swinging while the neck vibrates....... I would rather like to have a bit less nervous behavier of the tuner instead of 0.1 ct.
  9. If the statement "tube amps are fizzy and this is represented correctly by the Helix" is true, a tube amp powering directly a FRFR speaker should sound the same as the Helix powering the same Monitor but without cabsim and microphone or IR. Is it really like this? I never got the idea to try this while i still had tube amps, now i've no more possibility :( too late :D made about the same proposition nearly one year before https://line6.ideascale.com/a/dtd/Helix-Please-add-Microfone-angle-to-cab-parameters/817573-23508 But for the most people, still more amp and effect models seem to be more important. :unsure: I did'nt search but i hope wo don't have 50 same ideas and each one has just a few votes, while the voters for the 3546th boutique amp are united in one idea ;) Voted up your idea anyway ;)
  10. I did'nt know these IRs and just bought it. Thanks a lot for this hint, they seem to work fine for what i want. Otherwise, i don't like IRs to much due to their limited flexibility compared to models and the limited number of storable IRs. As a lot of comercial patches use certain IRs wich must be placed on certain slots, my IR banks are alreadey full. I won't need them all, but reorganizing everything wich concerns IRs would be a lot of work and i'm al lazy guy. So i still would prefer at least a vew Speaker models recorded off axis. Anyway - i like the sound with my FRFR monitor AND my headphones with this IR pack and that's way more than i had before. So thanks again!
  11. In my younger days we had a record in a studio of a big radio station, where they normally recorded symphony orchestra, jazz and chamber music. The engeneer had no touch with rock music. My amp sounded good to me as well on stage and in the studio (it was an Acoustic G112T with EV 12L) but listening to the records made my ears bleed. I suppose the mic was placed on axis of the 12L, but i don't remember anymore as this was 34 years in the past. So I understand the explanation for the fizz but not the reason why all amp/mic models should only have been modelled on axis? Are we shure that's the point or do we just suspect this? So after all, i understand when line6 models cabs and mics on axis but please - not exlusivly :(. If there's no parameter to change the microphone angle (Position edge/center) i would prefer to have the choice between let's say 3 positions. Tweaking with the high cut comes sometimes close but it's not the same, as the radiation pattern of a 12" speaker is a bit more complex than this.
  12. sorry, perhaps i did'nt understand the discussion right. I agree that the discussion about the headphone sound is important and a reason why i asked for a headphone out dedicatet global EQ in ideascale long time before. But it seemed to me that the impedance could be seen as the most important influence. As there are pros and cons for both low and high impedance in this thread, so this could indicate that the impedance is just not such an important factor. ;)
  13. hmm - as there are reported good and bad sounding headphones (with the Helix headphones out) with low and high impedance - so - is'nt this impedance discussions senseless?
  14. perhaps it seems like this thanks to online dictionaries :D and the possibility to describe in another way when i don't know the right expression. But imagine to search for a certain information in this huge forum when you have to google 2 words of ten :o Seriously, even in german forums, i cannot read every post in an interesting thread, i'm still not retired ;). So i fly with my eyes through the pages and am still able to find what i'm lookong for. In english or french: No chance :wacko: I think to remember a post where was said only to post in english to avoid multiple threads for the same topic. Therefore my question 'cause i'm not even shure if it was here at Line6
  15. Hi, while my english hopefully is'nt to bad, i admit to have a problem: Still in my mother language german it is'nt always easy to find desired hints and informations in the huge amount of posts and topics, so it's still more difficult for me in a foreign language. So would it be allowed to have threads in other languages (of course not only german)? I know that a lot of questions will be postet more than once this way, same for the answers. But i think, better an answer twice than just once while 80% of the world does'nt understand it ;)
  16. hey - this was a proposal for cowboydunnit. For myself, there are rather too much possibilities in one unit, therfore the smilies in my post ;)
  17. did look for this option too and did'nt find. But you can import an empty setlist to the place of the one you want to delete ;)
  18. why not linking two helix? ;) Doubles the dsp power, place in the paths, second pedal. And you can touch the two sreens (even if there's nothing happening) :lol:
  19. The input impedance does'nt make such a huge difference. A low value simply lowers the resonance peak (the amount, not the frequency) of the pickups, wich normally is between 2 and 4 KHz with a gain of 0 to 6 dB. As the Pots in the guitar usually build a load between 250 and 125 KOhms, the influence of the amps input impedance is'nt huge as long you're not going down to 100 Kohms. Choosing a higher value in the helix should'nt make a big difference, as the resistive load is mainly definied by the pots ;) Again: If the speaker/mic models of the Helix would'nt reproduce to much high frequencies, why a lot of people (and even prodfessional patches) feel it necessary to engage the high cut? Unfortually i have no access to my measurements of guitar speakers at work, but why a high cut at 6 KHz makes a big difference in sound where the modelled speaker does'nt output the frequencies above in a audible amount? And again: Of course you can get great sounds out of the helix, but it needs some tweaks wich are'nt necessary in the analog world. (By the way, the high cut is'nt a really sharp tool as it allows to change the corner frequency but not the slope). And because the helix want's to simulate this analog world, why this tweaks? So creating a sound is'nt equal to the analog world and we have to understand this to not to be frustrated. It seems sometimes to me, that the amp/speaker/mic models are designed to be reproduced by a guitar speaker wich does'nt make sense to me. Driving a moddeled cab thru a microphone thru a real cab to make it sound good without tweaks seems ridiculous and make the sound far more sensitive to the speaker/headphone sound. There must be a philosophy of line6 behind this behaviour (as it was similar in the pod family) but i just would like to know wich one?
  20. Hi, if there would be anything broken, i suppose you would'nt hear anything via xlr. So probably there's something changed in the input/output configuration/routing.
  21. made a similar experience with the headphone out and posted it months before. I understand that different headphones may be different in sound as they are vary with every other audio signal. But: I recognize the sound of a Marshall Amp when listening with different headphones, high end loudspeakers or the cheap kitchen radio. For shure with differences, but with the same character. With the helix, the sound of different speakers or headphones is variing far more than from other sources and this makes it difficult to dial a sound in or to use patces other people builded. Perhaps this is the reason why sounds from others often are not satisfying in another environment. In my opinion (i know that this is subjective and worthless), every output of a modelling amp should give s signal of a miced cab (if dialed in), without hiss and noise wich makes it necessary to use additional high-cut, as the original guitar speaker does'nt reproduce these high frequencies. So why it is necessary to reduce high frequencies if they should'nt appear in the signal? This point changes from source to source but seems always to be necessary to me if i don't use guitar speakers. I simply cannot understand why? For my headphones, i helped myself by inserting thin felt sheets (2 sheets per side seems the best with my hps) to reduce hiss that never would come out of a real guitar speaker. So i see two possibilities for this hiss and lifeless flat sound: 1. The modelled speakers have a wider frequency response then the originals. Why??? 2. The models represent speakers miced just on axis in the middle of the high beam of the guitar speaker. A position, nobody wants to listen to when not using a acoustic guitar. Nobody would mike a guitar speaker like this, so what's the reason? Some people turn their amp on stage for some degrees, others use tools as deeflex to avoid thhis high beam (wich is physically not to avoid with a 10" oder 12" speaker), but the helix seem to make a feaure out of it. That's the point why i suggested different microphone angles i ideascale, but for the most users, still more amps seem to be way more important.
  22. i have the same effect from time to time, but i think, people wich never experienced this won't belive it. Seems to me that the helix get's blind to all cabs. If the effect started, it can only be stopped by repowering the helix. Even the latest firmware releases did'nt fix it on my unit but - as said, it appears from time to time, not every day. Still hope this is a software thing and nothing wrong with the hardware.
  23. Hi, i had a similar problem during my first days owning the Helix. Sometimes, the preset sounds where OK (for preset sounds), but sometimes, after changing a patch it seemed like all the cab sims where eliminated from every single patch. Every sound with at least a bit of overdrive or distortion was fizzy and noisy. Sometimes it was OK again after powering the Helix down and up, sometimes a reset did help. Since the last updates (i think it was 2.0) the problem was gone for me and never appeared again. Normaly a certain patch with a certain input signal should shoud give the same output signal on every Helix in the world, but i think that's not always true. Lets hope that it's a software bug and not a hardware issue. So it might be a issue with pad, global EQ, cab parameters, but it might be even this bug i had at the beginning.
