FMP

FM percussion module using an old Yamaha FM chip

The FMP is a eurorack FM percussion module. Internally it uses the Yamaha YM2413 FM chip to generate sound and it is controlled by a microcontroller.
There are 7 parameters that shape the sound and with CV you can interpolate between two sets of parameter settings to generate a very dynamic sound. The FM chip also contains built in drum sounds, these are exposed in the drum mode. Here you can only change the level (and mix) of each sound and the pitch, but here you can also interpolate with CV between two sets. See for more info the manual or watch some demo video's (see below)

The diy version is through hole and comes with a programmed microcontroller and a tested Yamaha fm chip.
