I have the following setup.
Dreadbox Erebus synth Audio OUT > Focusrite Scarlett Solo interface Audio IN.
Arturia Keystep keyboard MIDI OUT > Dreadbox Erebus synth MIDI IN.
I can record the synth via the Focusrite in Renoise. Renoise detects the keyboard and I can use it to play notes. But How should I do to send the Renoise notes to the synth and record the result?.
