Default Hardware MIDI controller dial to selecti VST synth patches?

I have a M-Audio Axiom 49. I'd like to map one of the rotary dials to patch select changes for VST synths like Circle.

I found out, I think, using MIDI-OX & another keyboard with a dial that allows this, that it's CC 32.

I'm using MIDI CC mapper to try and accomplish this. Attached screen shot here

It doesn't work unfortunately.

Am I doing this right? Would appreciate any input on what I'm doing incorrectly.

Thank you, D

There is no universal way to change presets in plug-ins. Some VSTs do not allow that at all, other describe the way in the documentation.
F.e. for Circle2 you can find relevant information in "LOADING SOUNDS BY MIDI PROGRAM CHANGE" (page 84):
you select Bank (CC#0... probably without CC#32, but unclear from the documentation) and then send corresponding Program Change message (PC, not CC).

Alternatively, you can save some presets by REAPER (in the FX window) and then change them by corresponding actions. This works with any VST.

Thank you Asslow3, I didn't realize the difference between CC and PC (well, still don't but the fog is a little clearer).

Your response prompted me to pour through forum posts where I found a couple of very useful scripts by DarkStar, to view MIDI data in real time and to convert CC to PC data. Now I can change patches in Circle by using one of the mod dials on the controller.

View MIDI data in real time (I inserted an instance before and after the converter below to verify values)

JS for converting MIDI data from a controller (post #4 in this thread, further context/instructions in same thread)

Thank you, Darren
