This synthesizer line are not toys. Back in the 80s, YAMAHA used their famous YM3812 FM chip, used in the original Sound Blaster and AdLib Music Synthesizer PC cards. and put it in keyboards for the home market.

These little keyboards are incredibly fun to play, and the FM slider based editing is a delight.

If, like me, you like to cruise in the memory lane, this thing will bring you back to your first PC that was equipped with a primitive 2 operator FM sound synthesizer card. We used to think it was amazing compared to the square-wave based pc speaker.

I modified my keyboard with MIDI IN using a Highly Liquid UMR2 module.

Sorry. I did not keep any schematics since this module is so simple to install. If you have a polyphonic keyboard that tracks the notes on the keybed using a matrix, but lacks MIDI capabilities, this is what you need.

I you are looking for a Highly Liquid UMR2 module, the creator of the board stopped doing them, but he was kind enough to make the design "open source". In other words, anyone can make them legally."
