All VST3 applications in both VC5 and VC4 only recieve on MIDI CH-1.
I don't know if the VST2's that also have VST3 versions do work. The applications only delievered as VST2 in VC4 do recieve on other indicidual MIDI channels than MIDI CH-1.
The VST3 don't give any MIDI channel selection options in my DAW like the VC4 VST2's does.
How can that be? It's not good you can't use the individual MIDI channels no matter the plug-in you use.
My DAW is Studio ONe 3 Professionel 64bit, and i'm on Windows 10 64 bit.
Also it's not possible to use differnt MIDI channels in Analog Lab Multis, Matrix Zones, CS80 zones ...... Perhaps more.
