I commented on that just two comments above yours.

Totally. I started a thread on TGP, but I did not mark Frank or Eric yet. Might me about time to do so. https://www.thegearpage.net/board/index.php?threads/new-apple-macs-with-m1and-big-sur-performance-compatibility-issues.2200502/

M1 Mini 16/512. Helix Native in LPX is almost unusable, both in native and in Rosetta mode. I was able to run >30 instances @32 samples, but the UI is VERY slow. Adjusting settings is almost impossible. Would be delighted to hear from L6 about when to expect Big Sur/M1 compatibility.

I am trying to create a Helix preset with a BOSS SG-1 type of effect. To me, it seems like there is more to it than just auto swell. The SG-1 effect is described as first "filtering" the attack and then doing the volume swell. I wonder whether this is an accurate description of what is going on in the circuitry. https://circuitscheme.com/boss-slow-gear-sg-1.html Soundwise, I am not getting there with the Helix Dynamics-Autoswell. Currently trying to add compression before Autoswell. Still, I do not understand what the Rel. Offset parameter is supposed to do. Even with the most extreme settings, I do not really notice a dramatic change. Some people prefer the Vintage Swell Delay over the Autoswell Dynamics model, but I feel like this works for slow swelling of chords and textures only, not for riding the volume on rather quick single note lines.

I hear a strange pitch shifting effect with some amps. It is very pronounced with the Matchstick Ch1. When I play a D4 on the 7th fret of the g string, which is 293Hz, there is a very pronounced bass harmonic tone at about 150Hz, which is half the frequency of D4, but not quite. That bass note does not sound and behave like a natural harmonic tone, though, because when I move one or two frets down or up on the same string, the bass note is moving, too, but it is not at 50% of the note I play anymore. It sounds like a broken Octaver or something. Doesn't sound right at all. I am on firmware 2.92 and I can not say whether this effect was there before I upgraded. I recently switched to new headphones, and it might well be that I do now hear things better across the frequency range than with my old headphones.

Good point and great advice, Phil. It is also good to know that this occurs in another DAW, too. I am still puzzled because the Helix sample rate settings do seem to affect the recording offset. It might also be that I am not experienced enough to know that there always will be an offset and that I have to adjust re-amped tracks accordingly. If this can't be solved through improving the drivers, a hint in the Helix manual would be tremendously helpful.

Thank you. I do see these sample rate options in the Audio MIDI Setup, but everytime I tried to set it to something else than 44.1kHZ, it bounced back to 44.1. It did not seem to matter what the sample rate setting in the Helix global settings menu was, btw. What I just noticed is that this happens only when Logic Pro X is running. In any case, as you said, it does not help with the recording offset.

I stand corrected. I did more tests, and the recording offset seems to be bigger. I also noticed that in the MacOS Audio MIDI Setup, the Helix Ins/Outs sample rate is set to 44.1kHz, while in the Helix global settings it is 48kHz. I can not change the sample rate in the MacOS Audio MIDI Setup, but in the Helix Global Settings. I re-amped the sine wave with two different sample rate settings, and that leads to a different recording offset. Helix Ins/Outs Sample Rate 48 kHz (MacOS Audio MIDI Setup: 44.1kHz) Helix Ins/Outs Sample Rate 44.1 kHz (MacOS Audio MIDI Setup: 44.1kHz) The negative offset is significant in both cases, and in the latter example it causes phase cancellation that is audible, obviously. I am on the latest Helix driver (Line 6 Helix Driver 1.0.7), which I downloaded and re-installed two days ago just to be sure.

I am experiencing a recording offset with Logic Pro X, too. I am sending a DI track (sine wave, in this case) to USB 3/4 of the Helix and record USB 1/2 to a new audio track (empty preset). This is the re-amplification method according to the Helix manual. As you can see in the screenshot, there is a negative offset in the re-amped track. Through adjusting the Logic recording offset settings in the audio preferences by trial and error, I determined the offset to be -28 samples.

That is a brilliant observation. I heard the same thing with the exact same effects just recently. It is a beat or a glitch that's off from the setting in Rate/Note Sync. I use note sync, fwiw. I'll have to find a way to record it. This is the only bug report so far that might be related to what I am experiencing:

This helped me, too. Had trouble initiating Native almost everytime I started Logic. This thread is the only one I could find about this problem. This solution needs to be made available in the FAQ. Curious to see whether this is a permanent fix.
