Introduction
The VCO2100 is a highly accurate and stable voltage controlled oscillator module that responds to a one volt per octave
control input.
Five different waveforms are generated across the ultra audio, audio and sub audio range. Sine, triangle, sawtooth, pulse and
VC wave are all simultaneously available. The VC wave uses a control voltage to morph from a triangle wave to various
highly distorted square waves. The pulse waveform has a width CV input which can be swept from extinction through
square to extinction.
The sawtooth wave has been especially designed for optimal use with the Mini Wave Module.
Frequency Modulation can be applied to the FM input which can be switched to a linear or exponential response and AC
or DC coupling. This input has an attenuator.
The sync input can be used with a pulse wave to have oscillators lock together when they are close in frequency.
The +/- Octave input allows precision switching up one octave with a CV > +2.5V or down one octave with a CV < -2.5V.
An on board tune button connects to the + octave circuitry, providing a convenient resource for calibration.
