OK....I'll try to make this as clear as I can.

Current Midi setup & modules patching to the Midisport 4x4:
Port 1: Roland JV30 (want to assign the JV880 module to this port)
Port 2: Roland MBD-1 Drum/Bass
Port 3: Roland MVS-1 Vintage Synth
Port 4: EMU Proteus FX

A music buddy sent me a Roland JV880 which I'd like to incorporate into the midi chain above.
I haven't used the JV30 patches in over ten years.
So...I'd like to assign the JV880 to Port 1 and just use the JV30 as a controller only for all (4) modules.

My confusion: if I replace the JV30 midi in/outs with the JV880 midi in/outs on the Midisport is it still possible to use the JV30 as a controller only when it's not patched to the Midisport itself?
I just can't wrap my neurons around how to route the controller into the chain so it all works while in Sonar X3.

Thanks to anyone who read this and any G2 is welcomed.

A good day to all.....
