Here's a note to value plug. REquires Kineme midi tools.
I should add that despite using a "global" midi listener it only hears IAC and physical midi devices, not the "to vdmx" pathways etc that you can setup between apps. So in order to, for eg use midi from ableton, you need to go to audio midi setup, click on ur iac device, make sure its online, add a bus. Then route through that from ableton.
