Controller Fluid Fluid dynamics

In summary, a MIDI breath controller converts breathing to MIDI values, which are then used to control a MIDI instrument and produce sound. The ones I'm familiar with work through the use of a pressure chip.

If the flap were to react to the slow flow/low pressure spring should be rather weak, so the flap could easily dangle when you move the instrument.

Yep--that would be a problem. The pinwheel idea probably has similar problems.

Well, I can see why everyone uses a pressure sensor. :-)
