Eurorack Velocity Sensitive MIDI Test Keyboard
A single octave Eurorack size MIDI test keyboard.
This keyboard has a RP2040 microprocessor that scans a bunch of buttons using I/O expanders. Each piano key has two soft and silent silicone buttons under it; the time difference between switch contacts is used to calculate a MIDI velocity value.
