Oh, even more solutions! Thanks guys :)
> I have not completely understood your target, but is case you want change the patch using MIDI keyboard/controller, I can try to make something using AZCtrl.
My keyboard controller is AKAI ADVANCE61, connected via USB to PC. Synth is Korg M1R, connected to RME UFX MIDI1 output. Searhing suitable sound is slow because I can't reach the physical unit from the working position and I did not find a way to +/- patch number easily in SONAR.
> In the track Inspector click on the patch field and use Numpad +/-. Same for the Bank field.
I'll try this!
