Hi, with firmware 3.2.2 on MC6 mkii midi thru from DIN midi in to the DIN midi out does not seem to work. The MC6 reacts correctly to PC messages on its own configured channel sent to the DIN in and it communicates fine with equipment connected to DIN out. But any messages to a different channel than it's own seem to be ignored rather than forwarded to DIN out.
Is this expected? Is midi thru only available from USB in to DIN out?
Check your MIDI thru setting. You can toggle it with switches A + F.
