Add a MIDI-In port to your favorite game system with the handy Midify board. It's the perfect mod for those who are interested in playing a synth cartridge with an external controller or sequencer, or for those who want to turn a console into a MIDI-controlled noise maker. MIDI note on/off commands simulate button pushes on the game system, making it compatible with any cartridge. It's great for 8-bit and chiptune music artists.
