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…

I like Teensy but it looks like their boards are either low-inventory or out of stock too: https://www.pjrc.com/store/teensy41.html

Says one SKU of 4.1 is available with limit of 5 per person

And meanwhile the 4.0 is in stock in all SKUs with limit of 20! per person. https://www.pjrc.com/store/teensy40.html

This is pretty available. Especially compared to Pi

Also, Mouser expects 712 in stock within one week.

This is so cool! Interesting you can use normal mouthpieces. Curious how the sound works, does the reed need to vibrate like a real saxophone, or you just need to blow into it and some air pressure sensor picks up (forgive me I have no hardware knowledge)?

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.

No the reed does not vibrate. It's there to restrict the airflow and to provide a similar embouchure to a real sax. Some more details here: https://github.com/jcard0na/haxo-hw/blob/main/docs/assembly....
