Ok, I am routing my tracks like this:
Midi Track 1, and then assigning "a" to it so my tracks are listing this way for one instance of RMX
3-c....etc, the trouble is on playback. I am usingn Cubase Sx3.1 and my tracks are playing back with seperation in RMX but....in Cubase my mixer shows activity on tracks that should not be playing?!

So there is some sort of bleed happening and I am not cool with that.

What am I doing wrong?

Thank You to the Mighty Wise Ones.
