i think what the OP wants is to stop the controller from playing both the M! and the 1080. of course, i may be mistaken. if i'm correct, the solution can be as simple as setting the m1 and the 1080 to different midi channels. an even simpler sol'n would be to have controller play 1080 and m1 play itself.
OP, can you clarify?
