Question

Is there a way to hear USB audio when I am recording it from my Roland TR-8 Drum Machine?

I'm using Studio One 4 with Studio 194 interface. I know to select the Roland TR-8 Drum Machine as the audio interface in order to record multi-tracks to Studio One. But since I have to select the TR-8 as the audio device I cannot hear what is being recorded.

Answer 1

The Roland TR-8 is basically a MIDI Controller with it's own sample playback / synth engine in the sound module.

While this talks about recording an External Synth, in your case it would be recording the sound module inside the TR-8
