So I have finished the final 3D CAD files, and printed out the body. I'm having the keys cut out of carbon fiber, and then I have a bunch of prep work (sanding, filling, painting, veneering) ahead of me to to turn the 3D printed body into a 'final' instrument.
I'll be dropping all new electronics in this instrument, but basically the same setup. Teensy 4.0 with audio shield this time, and wireless MIDI, but the basics will be the same. Two MPR121s, pressure transducer and accelerometer/IMU.
