 Saturation: Increasing Saturation values clip the waveform, gradually molding its
shape towards a rectangular waveform. This results in a corresponding increase in
odd numbered overtones.
 Asym (Asymmetry): Tilts the waveform towards a sawtooth wave, making the sound
more edgy. Asym can be modulated by the sources found in the Mod and Via menus.
This allows you to create dynamic sound changes at the oscillator level. For more
information, see “Modulation on page 373.
Note: The basic waveforms of classic analog synthesizers can be easily reproduced with
the phase oscillator: sine, rectangular, and sawtooth waves are each the result of
setting the Slope, Saturation, and Asym parameters in different combinations. For
example, if you set Slope and Saturation at their maximum, and Asym at its minimum,
you will create a classic square wave. With Slope set to –0.20, Saturation at its
minimum, and Asym at its maximum value, you will create a saw wave.
FM (Frequency Modulation)
In FM mode, Oscillator 1 generates a sine wave. Its frequency is modulated by the
waveform of Oscillator 2. Please remember that Oscillator 2 must be switched on to do
this. The more complex the Oscillator 2 waveform, the more partials will be created (by
increasing the FM Amount) during the FM process. You can watch the display to see
how the sine wave takes on an increasingly complex shape.
The FM Amount parameter can be modulated by the sources found in the Mod and Via
menus. For more information, see “Modulation on page 373.
Note: While the phase oscillator is well-suited to simulations of analog waveforms and
analog-style sounds, FM mode offers bell-like digital tones and metallic sounds.
