The Drum Brain firmware provided with the MIDI Computer converts trigger pulses from eight analog percussion sensors into MIDI Note On/Off and Velocity data. With appropriate interface circuitry, such as the 9212K, sensors can be either Piezo Disks, Force Sensing Resistors or Electret Mics. The DIP switch select Basic Channel, 1 of 8 sensor-to-MIDI-Note# maps (one user programmable) and exponential or linear Velocity response.
