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…

Before I’d do any of that would be vibrato. Without it it is a emotionless keyboard with a blowtube.

Pretty challenging to do vibrato w/ momentary switches (discrete). For vibrato you need something like flexforce pressure sensors[1].

The video doesn’t seem to load on iPhone (Safari). It loads a tiny thumbnail, then just spins forever. Edit: it may be because I’m opening it from the mobile link (which sends the video to Safari), but I tried pulling up the repo directly in Safari, and it shows a whitespace placeholder for the video but that’s it.

FWIW, I just tried it on iPhone and works for me...

This is extremely cool. Surprised how good it sounds in the example video. Wish I knew enough about hardware to build one (OK, i also wish i knew how to play sax). Shame there's nobody shipping all the parts for assembly at home. In any case this is awesome, and one of the cooler things I've seen on HN recently!

I like Teensy but it looks like their boards are either low-inventory or out of stock too:

As the owner of a (recently revived) ewi-usb… I’m really curious about the mouthpiece bit. What kind of analog sounds are happening while playing this? Do you notice that reed age, strength etc are as impactful as on a real saxophone? Do you feel a need to swap mouthpieces for different styles of playing? I love the idea and ingenuity to make this happen!

Looks like just a pressure sensor. You might be interested in the KontinuumLab channel, from a guy who has done EWI projects with more sensors.
