Well, it's designed to run inside VST, there's not much call for sending
MIDI out again, so I'll plead ignorance there. Same with Sysex, VST only
supported Sysex very recently (i.e. not just on paper), so I don't handle
sysex yet.
Sysex is a tough one. You never know what's 'inside', is it a sample dump?,
a continuous controller?
I don't think there's much we can do with Sysex, except pass it to the
plugin.
