"Godwin Drummaker 45 Computer System with original Keyboard controller.

See video attached.

Mostly working but needs service.

Arp section not sounding. Drums section working but high pitched noise bleeding through.

Keyboard seems to be working fine.

Other few minor issues with the machine, it just needs a service and some attention from someone who had the time. Beautiful sounding machine."

MOD2 Prototype test | Seeed XIAO RP2350 based Drum module for eurorack

video upload by HAGIWO

":Almost all of the programs were generated by ChatGPT.
Since the circuit has been simplified, there are few CV inputs and the audio is output via PWM, but the RP2350 is fast enough that even a simple program can produce reasonably good sound.

Although there are no plans to use it as a VCO, it also supports V/oct.
