Hi Anon1,

To control a VST plug-in with MIDI CC# (Control Change) messages, you need to set up an instrument to handle that CC number.

1) Go into the "Instrument List" (F4), select the "Pitch/MIDI" tab or an instrument and make sure MIDI "Output" is enabled.
2) In the same screen, click "MIDI Settings". You will be presented with something like this: http://www.nashnet.co.uk/english/revisit/revisit0876.jpg
3) Change one of the MIDI Effects (0 = 0xx, 1 = 1xx) to the CC# you want to control - in your case CC#85.

Now, you can enter data in the pattern editor:

4) You will need to start a note of that instrument for the MIDI effect messages to be transmitted (otherwise reViSiT doesn' t know which instrument's settings to use!).
5) Then use the effect column to trigger the effect you just set up. eg. the 0xx effect. The effect 000 would send CC#85 with parameter 0 - 07F would send it with parameter 127 (note the use of hexadecimal).

Note: some CC# controls require two messages to be sent - an LSB and an MSB. If so, you'll have to set-up a seperate MIDI effect for each and use two pattern channels to send each message. I think, however, that you only need the one for now.

I hope this helps - let me know if you need more help.

All the best,
Chris
