This project is a 3U by 14HP eurorack-format modular synthesizer integrated modulation unit. It features at 12db or 24db per octave low pass or high pass Sallen-Key VCF, a full-feature envelope generator with auto-repeat, and a VCA. All stages in this unit are bypassable with CV inputs, and has a manual trigger or CV trigger on the envelope generator. All signal processing is done with an RP2040 microcontroller.

This project is a breakout for the Selector custom mixed-signal CPLD. It includes an up/down counter for a rotary encoder that is read from a SPI register. There is also an ambient temp sensor input that is also read from the SPI register, but also directly drives a cooling fan motor via a PWM output signal driving a power MOSFET with capacity for up to 24VDC on the motor.
