The general tuning of the 3 oscillators is done with the “VCO Initial frequency” potentiometer
by +- one octave per semi-tone.
For fine tuning, set the Fine tune potentiometer to +/- one semi-tone.
Depending on the position of the “Range” selector switch, the range is of +/- 4 octaves. It is
also possible to set it to low frequency position (LF – for low frequency). You will no longer hear
any sound, but can now use it as LFO source of modulation.
The impulse width applied to the “sawtooth”, “triangle” and “square” wave forms of oscillators
2 and 3, can be modified with the “pulse width” potentiometer.
Oscillator 1 possesses two audio outputs for the sawtooth and square wave forms. These can be
used simultaneously. The second and third oscillators possess four outputs for the sawtooth, sine,
triangle and square.
The frequency modulation inputs (FM Control) and Pulse Width Modulation allow the control of
these parameters thanks to the outputs of other modules (an envelope, a LFO for example) They are
all pre-cabled to a defined module in advance by the developer of the ARP 2600V. This is to simplify
