Earlier quoted context omitted.

Reading the assembly instructions it's only an air pressure sensor. You can use a real mouthpiece with reed or not, but it won't make noise actually. It also won't detect anything you do with your mouth.

Needs a reed sensor.

If your goal is full fidelity, sure, but they're trying to make a cheap practice device. If you want the former you're probably better off just buying something commercial, at least an AKAI.

Since it's using keyboard keys I'm guessing it doesn't have any analog touch sensitivity (?) Not sure if that would be even needed on this type of instrument though.

This is also true of the EWI, all of the keys are just metal plates that detect contact, and also generally true of saxophones (although very much not the case with clarinets, which have open finger holes)

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.

This is one of the coolest things I've seen on HN. I am definitely going to try to follow the instructions on this in the near future! I don't even play saxophone, but now I am not definitely going to learn. I would 100% buy one of these, if not 3 so I could give some as gifts.

Thanks for sharing and seriously, awesome project. Almost brings a tear to my eye.

Yes, there is no analog touch sensitivity on the sax: keys are either open or closed. The pressure sensor is for volume and note attack.

There exist analog keyswitches, have you considered playing with those?
