Yep, StuffMIDIMessage, obviously. But same is part of the Reaper API, which is accessible when you do a Reaper Extension DLL, which is dnamically linked to Reaper using the Reaper Extension specifications which provides the call location for the "StuffMIDIMessage()" function.
But MidiToReaControlPath is not a Reaper Extension DLL but a VST DLL, and hence is dynamically linked according to the VST specifications and does not know how to call "StuffMIDIMessage()".
AFAIU, the tricky part is to have a VST it access the Reaper API altogether.
