I have a Roland VSR880, Roland PC300 controller, Midiman 2x2, Korg M1R, Boss DR5 and a G3. The VSR880 is connected into the In A & Out A of the Midiman 2x2. The M1R is connected into the In B & Out B of the Midiman 2x2. The Boss DR5 is connected from the Midi Thru of the M1R. The PC300 plays the DR5(channels 13-16) and the M1R(only channel 1) via Metro.
How can I assign instruments to Channels 2 - 8? Is it done through Metro or does the M1R have to be set up a certain way?
