Over the past months I have been working on a digital/analog hybrid synth based on an ATMega328p (digital oscillators using various synthesis algorithms, MIDI processing and "user interface") and a CEM analog chip (VCF and VCA). This was very fun as I had no prior background with microcontrollers and more generally electronics when starting this!
The PCB design is not finalized (I had to made corrections after I received 2 days ago the proto I ordered), but the firmware is stable. People around me have expressed interest so once the PCB design is validated I will distribute 10 kits.

Any feedback will be appreciated!
