Tangible Waves - VCO
The VCO module is a "classic" VCO:
- two CV inputs 1V/octave
- MODulation input with Level-knob, switchable to frequency or pulsewidth
- PWM input
- Coarse / Fine knob for frequency
- Pulsewidth knob for squarewave
- Square / Triangle / Sawtooth output
This is best if you need an oscillator for primary musical / melodic use.
The voltage-controlled oscillator (VCO) is a typical analog audio oscillator with 1V/Oct pitch tracking for musical purposes. VCOs are one of the most basic audio sources in a synthesizer. Their sound is usually further shaped and refined by filters, wavefolders, voltage-controlled amplifiers (VCAs) and other audio effects.
Inputs
- CV1 - control voltage input for pitch frequency (1V/Oct)
- CV2 - another control voltage input for pitch frequency (1V/Oct)
- MOD - control voltage input for modulating either frequency or the square wave's pulse width
- PW - dedicated pulse width modulation control voltage input
- SYNC - resets the waveform when a trigger signal is received
Outputs
- 2x RAMP - ramp/sawtooth wave output
- 2x TRI - triangle wave output, quieter than the other outputs so it might need amplification via the 2SIGNALAMP module for example
- 2x SQUARE - square wave output
- BUS CV - pitch control voltage form the MASTER I/O module's MIDI-CV converter
Controls
- MOD DEPTH Potentiometer - attenuator for the MOD input control voltage
- MOD DEPTH Switch - switches the MOD control voltage target between frequency and pulse width
- COARSE - coarse tuning of the VCO frequency
- FINE - fine tuning of the VCO frequency
- PULSEWIDTH - manual control over the square wave's pulse width, control voltage modulation is added to this potentiometer setting
