Thanks for the feedback, Larry.

I can't imagine ever using the breath controller outside the context of my desktop environment, so performance isn't an issue for me.

I found a free VST called midiAudioToCC which translates volume into MIDI CC commands. Basically, something that could be used as a poor man's breath controller.

But... I tried it out with JABB and GPO, but the results weren't very encouraging - there was too much variation in volume - the flute ended up sounding more like a harmonica because of rapid oscillations in volume. I should play around with the smoothing and see if I can get better results.

Also, humming would probably work better than blowing into the mike. On the other hand, it seems to work fine for the iOS apps...

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
