=== Calibration ===
The software uses an automatic calibration of the base-line every time no pressure is detected. So even after replacing the membrane you usually don't have to re-calibrate the device manually. On the first setup you have to define by a single number the sensitivity of your setup (mainly dependent on you hall sensor, magnets and distance magnet vs hall-sensor) so that the maximum blow (where usually the membrane magnet hits the top acrylic plate) outputs a CC value of up to 127.
=== Instruments ===
Also other sample-based instruments, especially strings but also organs, can be articulated much nicer using a breath-controller. Often expression (CC11) or breath control (CC2) is supported - so find out. You can change the Arduino code to use CC11 instead of CC2 if you like, I prefer a little M4L device to clone CC2 to CC11 for this purpose...
