Here are the features of this all new midi board I designed , made and now distribute:


  • 64 outputs, 35 volt , 500 mA max

  • size: Only 100 * 130 mm: can fit in any instrument, even the smallest..

  • all ouputs are clearly marked on the board


  • Midi channel can be changed directly on the board by push button and LED, no need any computer. Useful "on stage" to play together with friends.

  • Responds to note-on, note-off,  all note off (CC123)

  • Considers note-on with velocity 0 as note-off

  • Supports MIDI running status

  • Easy mapping of outputs by «self-learning» with Midilector or with the freeware "Parametor".

  • ULN2803 chips are not soldered on the board. In case of an accident (for example a short circuit in a solenoid) they are very easily replaced.

  • New : For security, limitation of the notes number playing together. This feature can be set by the user himself with Parametor

  • Protection against bad polarity

  • Compatible with every midifiles player in respect to MIDI standard

  • The MIDI OUT socket acts as a MIDI THRU. That means that every message that arrived via MIDI IN goes out via MIDI OUT except active sensing messages.

  • On demand, one or more outputs can be programmed to respond to sustain or another control change of your choice

  • All other special programmations on demand
