I have previously recorded from my roland TD50x midi parts to 16 tracks of audio, by first changing the audio interface from my Presonus 16R, to the TD50x. there was a box in studio setup to change. but now there is no box and no TD50x to choose. this is despite that they are connected USB and playing a sequence in Cubase with the previously recorded MIDI drums plays the TD50x drum part. I don’t know what happened to change thus.
