Cybrid is an open-soure MIDI-controller

Cybrid is an open-source MIDI controller.

Cybrid is a DIY project I finished in 2020. The main goal was to turn a grand piano action into a MIDI controller. In digital piano terminiology instruments with a real wooden piano action are called hybrid pianos. I own one such instrument, the Yamaha AvantGrand N1X which is a digital piano with real grand piano action and realistic piano hammers that are stopped by a cushioning rail instead of strings. There are optical sensors that detect the hammer velocity and produce digital piano sound. In other words, it's a hybrid between an acoustic piano…
