After you do the steps outlined on your other thread:
Using the TI2 and running a signal through it simultaniously?
You just plug a MIDI cable: Kurzweil MIDI OUT -> Virus MIDI IN
If you want to get different sounds from the Kurzweil and the Virus even by having a single MIDI cable, you create a Setup on the Kurzweil:
- Set a Zone with a MIDI channel which the Virus is not listening to (on the Multi). This Zone will have the signal you want to process with the Virus.
- Set a Zone with a MIDI channel matching the Part in the Virus you want to control remotely. You can have up to 15 Parts on a Multi in the Virus (I'm not considering the Part dedicated to Process the signal coming from the Kurzweil) and you also happen to have 15 available Zones on the Kurzweil available to control the Virus (also not considering the Zone used to control the tone generator on the Kurzweil)
