"Erica Synths Eurorack DIY Synth Voice,
It’s a classic architecture synth voice with internally routed VCO-VCF-VCA circuit, but it also features a lot of patch points, so its also great for experiments."

"When developing Erica Black Series and Pico Series modules, we accumulated quite a know-how on compact and great sounding designs, and we decided to share some of those with DIY community. And therefore Erica Synths proudly presents – DIY Synth Voice module!

It consists of all essential blocks for versatile monosynth, and is 100% patchable for even more controll options. In order to make the module more compact and reliable in tuning, it has digital/analogue design. VCO and envelope generators/LFOs are digital, other parts are analogue. Digital parts are designed arround pre-programmed MCU board, which comes with a kit presoldered on a small contoller board. Chain up several Erica Synths DIY Synth Voice modules and you have a versatile polysynth!
