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.

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

I don't know. Looks kinda easy to do vibrato through your blowtube https://www.youtube.com/watch?v=XtsZZKZcNC4

It's tremolo, vibrato would be oscillating pitch. Real woodwinds can do both. And yes, Fender got them the wrong way.

If I had the knowledge/ability/skills to build an “emotionless keyboard with a blow tube” I’d be pretty damn happy. I don’t think a lack of vibrato diminishes what is going on here.

Am open sourced wind synth made with a custom keyboard? Pretty sick IMO

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

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

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
