In Widows 10 and Presonus Studio One 5 Artist, I'm unable to select separate, differing input and output sources. I want to use my Line 6 Helix USB output to record to an input track while playing back other tracks via my Soundblaster Omni soundcard. Very basic. I just want to add guitar parts to already recorded backing tracks but I can't setup Audio I/O with unique input and output. If I set to Creative Labs Omni, I can't record while the backing track plays back. If I set it to Helix, I can't hear the backing track. I can't split the audio setup to play the track output via the Creative Labs Omni Soundcard in Windows 10 while recording the input guitar signal from the Helix.
