Does anyone know how to get the N364 to transmit MIDI Control Change information.

I have a Roland SC-880 Sound Module and I'm trying to get the portamento function to work. It responds to Midi Control change as such:

Portamento On/Off -- Control Change 65
Portamento Time -- Control Change 5
Portamento Control -- Control Change 84

I don't know much about MIDI so could someone tell me how to do this.

THanks
