I was just thinking today how fantastic it would be if i could set parts on multi mode to 'midi out parts'.
Same key range controls
Same patch settings (i suppose the virus would sent the patch changes upon change of multi, or when you edit it)
Only difference being the virus controls other synths based on these controls rather than originating the sound itelf.
Random example; part 3, set to midi channel 2 between G2 and F#3, sends midi out messages on channel 1 (using the MIDI OUT port).
It would be even better if it were possible to enable the AUDIO IN on the same part so the virus can process the generated synth sounds if you connect it up.
This would save me endless trouble with midi mergers and splitters, etc. if i could just use the virus for it all.
