I’ll be hosting a DIY workshop at the Pulse Modular Music Fest where you can build the VCF-1 from kit. Entrance for the event is 10€, the workshop is an extra 25€, which includes the kit (PCB, Front panel and all components) So if you’re in the area, don’t hesitate to come and participate, there are plenty of fun things to do.

- Added a potentiometer for the saw animation in
