It looks like the latency is being reported properly in the ASIO driver. I just created a hardware Send in Reaper from one of the USB outs, and the re-recorded track is actually ahead of the original track by about 90 samples. So in this case Reaper is compensating for a conversion that's not actually happening. Hm, not sure if I understand what you're doing. Version 1) You're sending out a signal via USB Outs XYZ (shouldn't matter which) through one of the Helix' sends, then you reconnect it to the Helix' input (guitar input should be sufficient) and record it. In that case, the Helix should act every bit the same as it would when using one of the main outs. Without anything loaded, everything should function as on any typical multi I/O interface. Version 2) Or are you entirely bypassing the Helix' hardware and rerouting the USB "stream" internally? You know, the "hardware Send in Reaper" part is a little confusing - I'm not familiar with Reaper, is that a Reaper terminology to integrate additional I/Os or are you refering to the Helix' sends? Anyhow, in case you were bypassing the Helix' hardware, yet sort of emulating a hardware environment within Reaper by utilizing the additional USB routing options as kinda virtual audio cables, then your assumption might be correct. I am for now assuming that (2) is what you meant. However, whether the 90 samples in your example (which would match the value I've seen in opposite order) are "proving" that this is a defined value the Helix will have to report to the host regardless of platform is beyond me. It might as well just be coincidental. In case it's not a coincidence, it could of course tell us that the ASIO driver for Windows is in fact reporting the correct values to the host (which would be what you concluded already) so recordings are lined up properly whereas the Core Audio version comes with an offset. Could you do the same test I did, just re-recording something from the Helix' main out into the guitar in and compare things again? In case these recordings would line up properly, we should've nailed down the culprit, namely the Core Audio driver (which may or may not be of informational value for Line 6).
