Hello and thank you for the answer. Sorry for my English. I'm French.
I enderstand for the system track. So, for individual tracks, I press the button monitor, for example solo track 1, I choose a synth sound, press record to the midi recorder, precount 2mesures, and when I play keyboard, the sound is always a piano...??? Could you explain me the procedure, step by step, please? I would be very grateful. Thanks a lot for your help. Cordially. SERGE.
