VCO-SUB - Voltage Controller Oscillator
Introduction
VCO is a single VCO laid out in a similar way to the VCO sec tion you would find on a monosynth. VCO in cludes a glide
(slew) function, so this is a great bonus. The VCO can go down to low fre quen cies so they can be used as an LFO.
Controls In Detail
Tune
The VCO has a wide ranging tune control. Turning Tune alters the basic pitch of the oscillator.
Glide
Turning up Glide adds portamento to the oscillator, so the pitch will bend (slide) up or down to each note (as op-
posed to a sudden change). The higher the setting, the longer the oscillator takes to reach its new note. Not many VCO
modules give you the all important Glide control as standard!
Pulse Width
You can alter the pulse width (duty cycle) of the square wave. Turning
this gives a sound similar to chorusing. In the centre position a square
wave is produced.
Sawtooth Level
This sets the output volume of the sawtooth waveform output.
Square Level
This sets the output volume of the square waveform output.
Sockets in Detail
CV in
This socket is the pitch CV control input and is used to control the
pitch of the oscillator.
PW
This is a pulse width control CV input. Use a -12 to +12V voltage in
this socket to alter the pulse width of the oscillator square wave.
Sync In
This is an oscillator Sync reset input.
Sawtooth Out
This is the audio output for the sawtooth waveform. Its level is affected
by the sawtooth level pot.
Square Out
This is the audio output for the square waveform. Its level is affected
by the square level pot.
Sub 1 Out
This is a Sub-Osc output 1 octave below the main saw/square out-
puts.
Sub 2 Out
This is a Sub-Osc output 2 octaves below the main saw/square out-
puts.
Sub 3 Out
This is a Sub-Osc output 3 octaves below the main saw/square out-
puts.
Note; the Sub outputs run off the main square wave. If PWM is applied to the square wave, it may affect the Sub
outputs!
