Common parameters
The specific parameters of the various oscillator types are described separately, but there are also common parame-
ters that apply to all oscillator types. These are:
D Octave (OCT) knob - this changes the pitch of the oscillator in octave steps.
The range is ten octaves.
D The Semi knob changes the pitch of the oscillator in semi-tone steps.
The range is 12 semitone steps (1 octave).
D The Tune knob fine tunes the pitch of the oscillator in cent steps.
The range is +/- 50 cents (down or up half a semitone).
D Keyboard Track (KBD) - this knob sets how much the oscillator pitch tracks incoming note data.
Turned fully clockwise the pitch tracks the keyboard normally, i.e. a semitone per key.
D All oscillators also have waveform selectors and a modifier parameter. How the waveform selection works,
and what parameter is the modifier varies according to the selected oscillator type.
D Important to note is that if you have made a modulation routing to an oscillator parameter e.g. the modifier,
and then change the oscillator type, the modulation will be transferred to the corresponding parameter in the
new oscillator.
The same goes for all common parameters (tuning and tracking). If you switch oscillator type, all common param-
eters are left unchanged.
D Oscillators can be synced - see “About Oscillator Sync”.
D Any oscillator type loaded into the Oscillator 1 slot can also be amplitude modulated by Oscillator 2 - see
“About Amplitude Modulation (AM)”.
Analog oscillator
This is a classic analog oscillator with 4 standard waveforms. The waveform selector button is in the lower left corner
of the oscillator panel, but you can also click directly on the waveform symbols to switch waveform. The four available
waveforms are from the top down (as displayed on the panel): Sawtooth, Pulse, Triangle and Sine.
• The Mod parameter (PW) controls pulse width and only affects the pulse waveform.
By modulating the PW parameter the width of the pulse wave changes, allowing for PWM (Pulse Width Modula-
tion) which is a standard feature in most vintage analog synths.
q For a perfect square wave, set pulse width (PW) to 64.
