Synth add on programmer

This project started as I had a monosynth with no more room on the front panel and I wanted to add more options, but these options didn't necessarily need a front panel control so I came up with this Teensy based (but could be arduino) little programmer which stores values in EEPROM for recall at boot up. It drives a bunch of 595 shift registers and can be expanded as much as you want. It also drives a dual channel DAC for control over VCA's

I used some rudimentary resistor ladders driven from the shift registers to get control voltages for Electric Druid EnvGen8C chips.

It can be seen in use on my Hagiwo $9 monosynth
