5.2. Oscillator Types
Osc 1 and Osc 2 have fourteen Types in common; in addition, Osc 1 has one of its own (Audio
In) and Osc 2 has six unique Types that are designed to process the sound of Osc 1 rather
than create a sound of their own as well as an additional chord Engine.
5.2.1. BasicWaves
This Type blends the characteristics of the two traditional analog synthesizer waveforms:
the sawtooth wave and the square wave. Simple yet harmonically rich, BasicWaves mimics
the oscillator modifications possible with early modular synthesizers.
Morph
: smoothly changes the waveform from a square wave (0) to a sawtooth wave (50)
to a double sawtooth that sounds an octave higher (100).
Sym
: When Morph = 50 (a pure sawtooth), this control has no effect. When Morph is set
below 50, Sym changes the pulse width of the square wave; above 50, it creates phasing
between the two sawtooth waves.
Modulating Sym with an LFO when Morph = 0 creates classic analog-style Pulse Width Modulation
(PWM), but when Morph is set to another number, this modulation creates sounds that would have been
tricky to create on a 1960s lead synthesizer!
Sub
: adds a sine wave one octave down. This extra sound source, a
sub oscillator, adds
low-end girth to waveforms. It could be generated on 1970s/1980s analog synthesizers at a
much lower cost than adding an entire extra oscillator.
