  1. It seems there is no info in the Hx FL manual how to make it work on external digital clock (SPDIF input). Does it sets to slave after digital input is selected in preset or what?
  2. It seems there is no info in the Hx FL manual how to make it work on external digital clock. I am owner of Hx LT. It has no digital input (except USB) so I can not use it anyway but as a master it works on any sample rate gobal settings allow. Have you tried to disconnect Hx USB while using SPDIF? I know SPDIF should work independent but lollipop happens.
  3. Possible but not likely. 1. Make sure your Helix SPDIF is set to internal clock. 2. Make sure your DAW (or session) is set to the desired sample rate. 3. If 1 and 2 check other sample rates. 4. If nothing works, change Focusrite to digital master and Hx to digital slave BTW: If you are using Mac check which driver you are currently using. If not "downloaded multisample rate driver" you are using Helix Class Compliant. This may create some issues when aggregated.
  4. Interesting observations. Helix paths are stereo and no panning law is implemented, no avialiable documentation about it either, so it is really a measurement work to check if USB input is treated different than ADC. IIRC in Reaper, I had to deselect one of dual mono track routing to keep the Native level compatible with LT. If I didn't I would hit mono models with 6dB more gain. When I tested Helix hardware I don't remember any lack of unity gain. Helix instrument level is fixed at 11dBu at 0dBFS so if someone can set a different audio interface instrument input sensitivity to that value it should be fine (unless there is some issue you report) 1.9ms negative offset with USB reamping is IMO natural. This is Helix ADC/DAC latency and the Hx driver is not informed if ADC/DAC are in path or omitted. If they are in path once there is no offset, if two times 1.9ms positive offset is expected.
  5. Oh, really? If you have three intiger numbers: 1, 12, 65 and you want to rise them proportionally as so that 65 is 100, then you have to mutiply them by 100/65, right? 1.538, 18.462, 100, then to round them to integer values 2, 18, 100 (becacuse the sample rate does not change, right?) What happens to those differences? Don't they form noise? S/N ratio is the proportion of the loudest signal to the noise floor level. If the A/D converter has eg 105dB S/N ratio and you keep 10dB of headroom so your recorded signal can only have 95dB of S/N ratio, right? Still if it has 50dB S/N ratio before it hits A/D converter, it makes a small difference. You can actually make an experiment of putting the Helix fx loop before a high gain amp model.

    128 IRs

    Yes. The facebook Original and Official Group. Tuff threads are removed, users not sharing appeciation are blocked sometimes. Sure Fractal DSP power is 4 times as big as Helix, IRs can be 4 times longer and you can have 20 times more, but AxeFxIII costs 4 times as much. Considering some of Hx DSP blocks are as good as Fractal ones, it it still a bargain.
  7. I do not have Hx Stomp but I remember somebody on this forum constructed Expression Pedal and a switch for Hx Stomp. I suppose they are not mutualy excluding. There are some expresion/volume pedals on the market. Their idea is similar but due to a differences in construction they may not all work right out the box. Using MIDI swiches is nice idea, you can go beyond two avialiable.
  8. The PreDelay adds to total reverb time. 130ms multiplied by the speed of sound (0,34m/ms) /2 for the return, equals 22m to the nearest wall. I know, I am a strange cookie. :D
  9. Somebody may say Strymon uses the whole Sharc DSP but as far as I remember Hx is 450MHz and Strymon 266 or 300Mhz, also Strymon is advertised as being 96kHz sampling rate, so probably Strymon reverb algorithms would use less than 50% of one Hx DSP path, not mentioning Strymon does not have to optimize them to lower DSP resources just because their target likes "hardware modular" approach to FX products and saving 3$ on a DSP clock would be weird. :) I think the reverb quality is all about its algorithms and the Helix platform is waiting for them. Edit: There is one more Sharc DSP platform - UAD, based on the same 450Mhz version: From DSP charts (one DSP usage): Lexicon 224 Classic Digital Reverb 15.3% 17.0% Lexicon 480L Digital Reverb and Effects 59.9% 60.3% EMT 140 Plate Reverb 14.6%15.0%
  10. It is cool. Hx Stomp plus: 5 more FS - 20$ each Hands Free PE - 15$ One snapshot more - 15$ 6 switch looper access - 20$ And it belongs to the Family for free unlike POD go ;)
  11. Actually they suck! I have watched Jason Sadities video on reverb comparisions. He took Legacy Plate and compared it to Stymon, Fractal an IK Multimedia. The results were only IK plate was worse. The conclusion was - nobody is able to tell a difference. If one is - cork sniffer alert! ;) I do not posses neither of the plates he used for a blind test so I am not able to replicate his demonstration but I can compare Helix Legacy Plate to the plates I use nowdays. Being sound engineer for 20 years I had a chance to listen to some real plate reverbs and a lot of digital emulations, cheap and expensive ones, starting from Alesis Microverb, , Digitechs, Lexicons LPX, MPX, PCM and so on. I remember I sold my TC M5000 couple of years ago after I compared it to Bricasti M7. No, I do not have M7 now to compare either. Back to the test: UVI plate is CPU hog so it wouldn't be a fair comparision. What about quite cheap (50$) and DSP resources light Valhalla Plate? Please, make a comparision by yourself. For me it is a night and day difference. Valhalla demo is free. https://valhalladsp.com/shop/reverb/valhalla-plate/ And for Line 6 fanboys: I know the Legacy Plate is taken from POD HD, I do not claim it is not playable - if you do not have any other plate reverb to compare you can even claim it is decent. Not for me - if I have to low pass filter at 1kHz to get rid of that awful claustrophobic, concrete feeling, grainy and messy mid/high range I just choose anything mercyful instead. Sometimes I ask you - what reverbs you think are worse than Helix reverb algorithms? They say Kemper ar Mooer. Maybe. Maybe just single Sharc DSP is not capable of producing anything attractive in the reverb department any longer due to its low DSP power? IDK but I do not think so. Sharc with good software can deliver even in 2025. To Line 6 whoever: I still hope there is somebody at Line 6 still developing reverb algorithms and some day they will be avialiable to me and I could call them decent. Yes, if the third party companies would release their software for the Helix platform I will pay for Valhalla. For the original poster: I have checked that plate mono and stereo. Nothing really bad is happening there. It sucks in both cases.
  12. Ola is the metal guitarist. He likes low frequency resonances. I don't really understand Igor's position: either Ola is cheating or his IRs just do his job of palm muting bass resonances correctly, but showing those resonances are present on the waveform and pops out proves nothing. If your position is correct - comparing two normalised IRs we should pick brighter as better which is not true. No. You can set a level identically only using one type of meter. In case of volume you have three types: Peak, VU (that corresponds to RMS) and Loudness (heavilly windowed and frequency weighted). In case of the Loudness Meter giving the best "perceived reference" you also may notice there are two readings: momentary and integrated, so this is possible you can not get consistent results when comparing eg. different gained amps with each reading. The results variation will be affected by a dynamic range of a given samples. I would trust integrated value if a given samples to compare are similar. In case of that video the goal is different. Ola likes LF thump, Igor likes balanced. In the mix each set of tracks could make different issues with the rest of the instruments and also can be mixed differentlly - thrashy or djenty ;) So your conclusion is almost right. ;)
  13. That is really interesting. Maybe you use the wrong meters? If you are comparing loudness you shoud use the loudness meter. Yes. This is epistemological question. If the epistemology is "Whatever works is what works" and YMMV then Igor Stolarsky, showing a waveform to prove Ola is cheating, is wrong. So YMMV approach is basically "I do not care what is true". I proposed the experiment the other day of leveling three factory presets to equal loudness. If our ears are the best tool we shoud repetiedly be able to make it and our results should be the same, shouldn't they? Spoiler - they are not. Only loudness metering readings are consistent. BTW: I asked Igor a question. If this is the case Helix stock cabs are quieter than any normalised IR, why? He did not answer.
  14. When returns are set to Line level the Impedance is 10kOhm and 1MOhm at instrument level. 10kOhm input impedace massively reduces the resonance peak of the passive pickups circut and line level is 8dB higer.
  15. To give some demonstration what I am writing about: This is Echoplex EP-1 sound sample: This is UAD version of Roland RE-201. To give Helix a justice with comparision one needs to consider how much DSP power it eats (for one 450Mhz Sharc) and the price. Of course there are some other RE-201 emulation plugins: And finally my favorite Memory Man model taken from old Avid Eleven Rack - so avialiable both as a hardware and a plug in.
  16. He is. He has demonstrated differences in a frequency response caused by various loads. Then he has found the answer in The Helix Manual. That document is the only wisdom source of that video referenced a couple of times. I personally find it hilarious when youtubers ignore there are other you tube channels covering the subject (not mention googling) and a better literature than The Helix Manual. Breathing. I was the second one. The first rd2k comment was brilliant. I do not understand crediting me for that. ;)
  17. Thank to The Academy! :I love You All!!! :D https://images.app.goo.gl/XtzPeD2Po4z62er2A
  18. Yeah. If one knows cery little, his life is full of miracles, magic and guesswork. But kudos for demonstration! I love it!
  19. Albeit be aware that the both methods have their pros and cons.
  20. I am so sorry. That was off top. I should be punished! This is kind of idiom my english understanding is too poor to comprehend. You may be right! I am so sorry to use Jesus in my comment. BTW. What is your opinion on Helix Input Pad Wowness and Attenuation of a Guitar Signal Wowness? Is thinking about a demonstration obnoxious for you?
  21. Cool! I like a part "I am not an expert, so it was a lot of guess work" and that enlightement mood of that video. :D If somebody is a guitarist and maybe the guitar playing is his job for a living, why not learn, read, watch a yt video about basic fact about the tools he uses? For example that: http://www.buildyourguitar.com/resources/lemme/
  22. Because (from the same page) "The meter measures output level". Green = Good, Red = No Good. You can check if your signal is clipped by monitoring direct input with your DAW (USB7 input). You can even demonstrate it to anybody else. Or guess what, you can use built in meter after a volume block and check what +dB value gives you Red = No Good. Bye bye. Take care.
  23. I am sorry but the dynamic range is not even remotely related to the maximal amplitude A/D converter can accept with no clipping. If your A/D converter has 123dB dynamic range and you keep 10dB of headroom your dynamic is 113dB. If you switch 6dB pad on your dynamic range is 107dB. Because it obvious. The Helix manuał is for guitarist with no basic understanding how electricity works. It does not contain any technical information nor specs and sometimes is misleading.
  24. I don't believe neither one, but I can make an experiment of inputing +13dBu sine signal and check if it clips. I believe the input pad purpose is simple - to attenuate signal before A/D conversion. I am almost sure now why Helix users like attenuation. The first time I compared Helix OCD with my analog OCD it turned out gain control "pot taper" is different and I have go below 1 value to get 10 o'clock OCD position. I had very same experience with Vox AC30. So the attenuation just helps to set proper gain in the "clean" range.
  25. Not at all. This is why I asked about a clarification. While I believe instrument level (+11dBu=0dBFS) is properly chosen by Line 6 developers and supposedly used for device modeling I also noticed that preamp and amp models overdrive sooner then their analog counterparts. In case of preamp models it is hard to keep any clean headroom with at least unity gain. Still "input pad superiority" is mentioned quite often, so I wanted to evaluate what is the orgin of that conviction and possible method to test it. Peace brothers and sisters. Amen and Awoman!
