Nice!!!! I think this is a great step ahead in the pd integration with other software!!! Joseph you are doin' a really great work!!! ...Is it possible to route midi messages to and from pdvst?
In my thinking, the VST host should be handling all MIDI I/O. So you can use the host application's normal method of routing MIDI data to VST plugin parameters, and in your Pd patch receive the parameter value with a "receive rvstparameter<n>" object, where <n> is the integer index of the parameter.
