does raising the internal processing level increase the volume recorded through usb-audio?

I think it does, but perhaps the internal level settings only influence play back volume, but as long as there's no sound clipping you can record quite loud volumes through USB.

it usually comes through very low volumes at 0db internal processing recording usb into ableton. ill have to check to see if it does increase it later when i can.

I'm 95% sure it does. At least I have a very strong recollection increasing it to boost USB input.

hint: lower the volumes when recording into ableton then after raise the volumes up to a reasonble level and add some "Upword Compression" works for me everytime.
if this works for someone let me know thanks!
