Welcome to MIDI to Anything™

Most people would love to listen to live music performed in their living rooms, but don’t want those unsavory musicians hanging around. Ugh. So, here we have cataloged ‘MIDI-to-anything’ interfaces, used to MIDI-fy custom Nickelodeons, Orchestrions and all sorts of mechanical musical instruments, new and antique. That way, folks can score ABBA MIDI files from the ‘web and have them play automatically on an accordion in the privacy of their own homes. There continues to be a lot of interest in this type of project, so please let me know if this list has been helpful. contact

I am listing only a small portion of the manufacturers’ data below. Please inform me of any corrections or suggestions. For a terrific reference regarding adding a MIDI interface to an existing acoustic instrument, please see the archives of the excellent Mechanical Music Digest (MMD).

For great examples of what can be accomplished, please see:

Hut Music & Electronics

MIDI Encoder and Decoder boards. Example:

MIDI Decoder 128. Hut-128“This is a full 128 note MIDI decoder, professionally made printed circuit board. Capable of driving magnetically-driven devices such as solenoids, electromagnets, motors and lights up to 35VDC/500mA per note. Perfect for connecting a MIDI source, such as a MIDI keyboard or PC to a real acoustical instrument fitted with electrical drivers. We use this decoder in our electrically driven pipe organ valves. MIDI ranges are re-programmable.” Cool.

Orgautomatech

MIDI Encoder and Decoder boards. Example:

  • 64 outputs, 35 volt , 500 mA max Orgauto64
  • Size: Only 100 * 130 mm: can fit in any instrument, even the smallest.
  • All outputs are clearly marked on the board
  • Midi channel can be changed directly on the card by push button and LED, no need any computer.

DIY kit version may be available. Also available: A cool MIDI Detector board to observe data activity.

MIDI CPU encoder.liquid-cpu
Attach switches, switch matrices, potentiometers, rotary encoders, and digital & analog signals. The MIDI CPU generates any kind of MIDI output.

Also available: MIDIWidget and UMR2 Universal MIDI retrofit board.

MIDI-Hardware.com

Quite a range of MIDI encoders and decoders. Example:

  • Converts MIDI notes to 64 digital logic outputs.mideco64
  • Pulsed modes possible, with constant duration and velocity dependent
  • Dual coil control in SAM control mode (32 output pairs)
  • Can drive indicator LEDs directly at 3-4mA
  • MIDI THRU for chaining the boards, or any MIDI equipment

MIDI Boutique

The mother lode! A VAST array of inexpensive MIDI encoders and decoders, several of which are re-sold by some of the folks on this list, I believe.

Example: Model MDEC32 MIDI-to-Parallel decoder with 32 TTL-compatible outputs

jw Electronics

MIDI Decoder and Encoder boards.
Example: Model MTP-7 MIDI-to-parallel decoder board:

  • 32 note outputs J-Omega
  • Alternative option has 28 note outputs and 4 program change outputs
  • Any output can be mapped to any MIDI note – ideal for non-chromatic instruments
  • Outputs can sink 500 mA @ 35 VDC
  • Easy installation with screw terminal connections
  • The cost of this unit includes programming, installation instructions, delivery and technical support by e-mail/telephone.
