Sorry for the delay mate... ok....
In Midi Prefs...
Both Virus TI Synth & Midi Track input & output set to ON
Put the VC on MIDI track 1 and set up as follows....
(All Ins)
(All Channels)
(Monitor in)
(Audio to master)
Go to MIDI track 2...
(All Ins)
(All Channels)
(Monitor in)
(MIDI to... 2-MIDI)
(2-VirusTI)
Go to MIDI track 3...
(MIDI to... 3-MIDI)
(3-VirusTI)
And so on for all sixteen channels...
Hopefully, that'll work!
Let me know if you still have problems. Cheers.
