Editing this post as I reverse engineer this midi piano...

I have some extra parts from a cheap 88-key midi keyboard.

The keyboard has been having some issues so I opened it up to see what is inside.

It uses an "NXP LPC2101" mcu to transmit keyboard data via an SPI serial interface to an "NXP LPC2136" mcu then MIDI out.
