Recommend a compatible audio interface (2 in 4 out)

After a brief overview of the app and the manual, there doesn’t appear to be any way to access any outputs of the sound card other than 1/2. Looks like just a software issue, as other apps are able to do it. If anyone else has different info please let me know.
Having a great time with the app so far!
Steinberg- bring back the “true tape” or whatever that input saturation effect was back in the day!

Thanks! :smiley:
