How Do I Use Another Keyboard To Play A Second Patch In Virus TI?
 

Forgive me for my lack of knowledge about the Virus TI or MIDI.

I have an old Roland JV-80 connected to the MIDI IN of the Virus TI Keyboard.

I want the Roland to play a Virus patch and the Virus to play a different patch.

For example:

I want to make the Roland keyboard to control a piano patch on the Virus TI and I want the Virus TI keyboard to play a Jazzy Rhoades.

How would I split up patches like this?

Thank you!
