  Haxophone, an electronic musical instrument that resembles a saxophone

  

Actually the pressure sensor is on the PCB. Pressure is transferred from the mouthpiece through a flexible silicon pipe. You can see the details in the assembly instructions here: https://github.com/jcard0na/haxo-hw/blob/main/docs/assembly....

  Teensy Audio Library

You can overcome the RPi scarcity by migrating the code to the Teensy platform, which aside being cheaper and less power hungry than the 2,3,4 RPi, is a lot cheaper and more easily available. Not an easy task since there's no Linux under the hood, but there are some excellent audio/midi libraries to help. They already built commercial-level synthesizers with it. By combining the breath sensor data with other pressure sensors you could end up with a very expressive instrument.

  🎼 Isomorphic musical layout engine for LinnStrument and Launchpad X, with DAW/Synthesia visualizer

I own a LinnStrument and it's fantastic. I created a custom note layout for it to make it easier to play: https://github.com/flipcoder/linnstrument-wholetone. The firmware is also open source. It feels like the Linux of instruments.
