=== Cleaning ===
A major issue with many (commercially) breath controllers is the cleaning of the device. As moisture from breath accumulates fast, I wanted a breath controller that can be cleaned and dried easily - even the pressure sensor itself. My design avoids tubing and by removing a slider, the inner parts of the pressure sensor is accessible for easy cleaning and drying. If you remove the top plate with the hall-sensor everything can be rinsed under water.

=== Instruments ===
If you own Native Instruments Reaktor, I like to recommend the free community instruments especially the "Silverwood" ones from Chef Singer. [[https://www.native-instruments.com/de/reaktor-community/reaktor-user-library/entry/show/12303/ Silverwood Flute]], [[https://www.native-instruments.com/de/reaktor-community/reaktor-user-library/entry/show/7854/ Silverwood Clarinets]] as well as [[https://www.native-instruments.com/de/reaktor-community/reaktor-user-library/entry/show/12419/ Silverwood Tenor Sax]] are very good sounding instruments as they are using pysical models to synthesize those instruments. Don't forget to add a little reverb to make them sound really great.
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...
