Overview
ClariMIDI is a MIDI wind controller based closely on a standard (Boehm) clarinet layout.
- 3D printed body
- 7 touch keys (the ‘holes’)
- 18 press keys (the ‘keys’)
- Breath sensor
- USB MIDI
- OLED menu
- Raspberry Pico microcontroller
It is specifically targetted at clarinettists who want to play a wind controller.
Standard clarinet fingerings are used, and the key layout mimics a normal clarinet.
N.B. This is a MIDI controller, it needs to be connected via USB-MIDI to a synthesizer to make
any sound.
