3340 VCO
3340 based analog voltage controlled oscillator. for eruorack modular synthesiser. Core circuitry can generate 3 different wave forms (Square, Triangle and Ramp) and it has a triangle to sine converter. It has hard sync and soft sync inputs, Linear Frequency Modulation input and also 1 volt per octave input with solid tracking. Pulse width can also be adjusted for square wave and it can also be modulated with external CV (0-5V). When a jack is inserted in PWM CV input, the PW potentiometer works as CV amount.
Available as PCB + Front Panel Kit and built unit. Front panel is also made out of PCB and screen printed by hand.
