FuniFi CiiVii is a compact, programmable control voltage (0-5V CV&gate) controller for synthesizers with analog inputs. There is a popular ATtiny85 microcontroller in the heart of the device which can be progrmmed with Arduino IDE and collection of example patches for sending analog voltages via 12Bit DAC and protective OpAmp. Assembly is easy, just a handful of inexpensive componets and through-hole board layout. 

FuniFi CiiVii was developed as a simple learning project for introducing soldering and coding for synthesiser hobbyists. PCB design was made with svg2shenzhen DIY PCB design tool for Inkscape
