Hi again! Well Phil you said, that the new protocol wouldn't be understood by anything. So why not first take it easy and take a look at what already exists. OSC was mentioned here a couple of times? Might that be an idea? And about the two APIs: why not? If you think about it thorroughly I'm sure one can come up with a protocol, of which MIDI is a subset. Thus some interaction between to apps (one using MIDI, one using the new thing) could be possible. At the moment we have audio and MIDI ports, add a third kind of ports. And thus if you use plain old MIDI there's no more overhead, than there should be.
