22.1.2 Oscillators
Display and Shell
Parameters for the two
Oscillators.
Analog's two oscillators use physical modelling to capture the character of vintage hardware
oscillators. Because they use modelling instead of wavetables, they avoid aliasing.
Each oscillator can be turned on or off independently via the switch labelled Osc 1 or Osc
2 in the shell, and the oscillator's output level is adjusted by the slider to the right of this
activator.
The F1/F2 slider controls the balance of the oscillator's output to each of the two lters.
When the slider is at the center position, equal amounts of signal will be sent to both lters.
When set all the way to the top or bottom, signal will only be sent to Filter 1 or Filter 2
respectively.
The Shape chooser selects the oscillator's waveform. The choices are sine, sawtooth, rectan-
gular and white noise. When rectangular is selected, the Pulse Width parameter is enabled
in the display, which allows you to change the pulse width of the waveform. Low Width
values result in a very narrow waveform, which tends to sound tinny or pinched. At 100%,
the waveform is a perfect square, resulting in only odd harmonics. The pulse width can also
be modulated by an LFO, via the slider next to Width. Note that this parameter is only
enabled when the corresponding LFO is enabled.
The Octave, Semi and Detune knobs in the shell function as coarse and ne tuners. Oc-
tave transposes the oscillator by octaves, while Semi transposes up or down in semitone
increments. The Detune knob adjusts in increments of one cent (up to a maximum of three
semitones (300 cents) up or down).
Oscillator pitch can be modulated according to the settings of the Pitch Mod and Pitch Env
