Somewhere in a huge PDF or Web knowledgebase is a list of all the available techniques that are considered Class Compliant, and OS programmers and interface manufacturers agree to implement those techniques - but they each do it very slightly differently. Different audio interfaces use different techniques. If you check out the link my comment above, 's a partial explanation for this.Д«asically, there are about a million (well, several dozen) subtly different ways that a particular audio interface might negotiate its communication with a computer.

I'm not an audio hardware or driver developer, but I do know that there's much, much more complexity inside how a class compliant USB audio interface works than what appears to you or me on the surface.

I'm not Digital_Igloo, but I may be able to explain what you're seeing. I think that the bug comes when a program try to send and receive simultaously audio data to Helix, because I've can listen the Helix through USB connection, and starts to corrupt audio when I try to record monitoring the input. I am also using a Behringer usb interface, class compliant without any driver, in another mac with El Capitan without any problem. My Roland can be used full featured with its driver, or as more simple class compliant unit.

First of all, thanks for your effort in supporting Helix. So if that means the Helix's audio is also fixed, maybe Line 6 won't bother writing a custom driver (or whatever it is they've been working on) after all. It sounds like the developers at Rane are also seeing an improvement in El Capitan 10.11.4. Pops, crackles, and other glitches along those lines are nearly always clock issues, and so it seems reasonable to assume that the Helix is probably using the same technique since it has the same issue (under the same circumstances, OSX 10.11.0-10.11.3). independent of the OS) to serve as the master, and using the 'implicit feedback meethod' which I'm not familiar with in detail, but it sounds like one of several ways to implement this. They describe that in their USB 2.0 audio class compliant devices (of which the Helix is also one), they're using a specific clocking technique which had been recommended by Apple several years ago: generating its own clock asynchronously (i.e. The news on 10.11.4 so far looks promising: This is interesting - another manufacturer dealing with a similar issue.
