Even VCO

High Precision VCO with Octave Select

Module in last stages of developing. Information may change without any notice.
This is an voltage controlled oscillator (VCO) with great precision, designed to be stable even in the case of power supply fluctuations.Supplied with a octave selector of 10 positions from 32′ to 1/16′ (C0~C9).
Outputs:
Triangle
Ramp
PWM
Sine
Even (waveshape with emphasis on the even harmonics)

Inputs:
Hard sync. This forces the core to down in the event of change to zero of the input
V/oct. Two inputs fro pitch control summed to the main octave selector and the tone control.
FM. Linear pitch control.
PWM CV. Pulse width control summed to the potentiometer.

Module is available with 3.5mm jacks , bananas and also as DIY kit
