3340 Based VCO
Module by Ground Grown Circuits
3340 Based VCO
14hp, 38mm Deep
Inputs: 1x Volt per Octave CV, 1x Frequency Modulation, 1x Pulse Width Modulation, 1x Shape Modulation, 1x Sync
Outputs: 1x Triangle, 1x Ramp, 1x Saw, 1x Shape, 1x Pulse
Controls: 1x Coarse Frequency, 1x Fine Frequency, 1x Pulse Width, 1x Shape, 1x FM Amount, 1x PWM Amount, 1x Shape CV Amount, 1x VCO/LFO Switch
Shape output is rectified and offset triangle wave, so with Shape knob centered with no CV, Shape out is a triangle wave at double the frequency of the other outputs. Shape CV input is normalled to saw output.
