Brains: PJRC Teensy 3.2 microcontroller dev board (Cortex M4)
USB: Micro USB jack, class compliant USB MIDI
Type of sensing: Capacitive, using built in Teensy cap touch sense and 3x the MPR121 chip
Sensors: Touch keys and rollers, pitch bend pads (proportional), vibrato/portamento lever, breath sensor, bite sensor (for vibrato or portamento) and lip sensor (extra controller)
Breath sensor system: Closed (like the Akai EWI1000 and the original Steiner EVIs and EWIs), NXP MP3V5004GP piezoresistive transducer, 0 to 3.92 kPa
