VST parameter changing

October 15, 2009 | 12:43 am


I’m using my VirusTI hardware synth’s vst im max. It works, the VST comes up, i can get sounds out via the [midievent 144 $1 $2] message. what i want to know is how do i change parameters on on it? I have the full list of CC references for my synth but i cant figure out how to change them via the vst object..any got any ideas? Also silly question i know what does the $1 and $2 mean in the midievent message..

Thanks folks!

Ok, my snyth/vst can handle up to 16 different instrument parts,so ive got it to list the parameters out the 4th outlet, the parameters listed as [1]FilterCutoff, [1]FilterReso, [1]OscVolume+Sat, [1]Softknob1, [1]Softknob2, [1]Softknob3 then repeated again for each channel [2]FilterCutoff, [2]FilterReso etc… then once that was finished it listed a bunch of (unmapped) messages. so i have got those parameters working. but this is obviously not all the possible parameters. i have a CC and Sysex list of all the parameters for the virus…how do i changes these parameters?

If I remember right, you just send a pair of numbers: (ccNumber ccValue). Unlike midi notes, you don’t have to prepend a word onto the front of the message. I think I learned that from the Help patch for the VST~ object.

You might try it with another VST …

I don’t mean to give up on the virus VST. I’m just saying that trying a different VST could help you get some idea of whether the fault lies with the host or the VST.
