When using a multitimbral vsti, ProteusX2 in this case, I can't get the Virtual midi Keyboard to play anything but channel one. I have a sound in channel 2 of ProteusX2 but can't get it to play. I tried using Trollo (A keyboard vst) and can get it to work. It will play any of the channels and their voices. The problem with Trollo is that I am getting considerable latency. Using the Reaper Virtual Keyboard there is very little, if any, latency. Is it possible to have the Reaper keyboard play the various channels? I have tried everything I can think of. When I switch to channel 2 I get silence.

The virtual MIDI keyboard only sends MIDI on channel 1 Meanwhile you could insert IX's MIDI_Tool in the FX chain before Proteus to change the channel (and if useful, automate the Output channel switching). HTH

Good question.

MIDI output channels in the virtual MIDI keyboard, coming soon.

Now they're just teasing us with upcoming features. :)
