parameter as you change it. The Symmetry is shown in the Waveform
display.
This parameter can be modulated using the Mod Matrix (Osc / Symmetry).
The Phase parameter allows adjusting the phase at which the Oscillator
starts when it's triggered (by a Note being played).
Below the dial is a switch that allows you to set how the oscillator starts:
Phase: The Oscillator starts with the Phase set by the Phase dial, except
for bound (held) notes in Mono Mode (Voices set to Mono). In this case the
Phase of the Oscillator of the new note continues from where the Phase in
the previous note was.
Free: The Oscillator always runs continuously, no re-starts
The Phase parameter can be modulated using the Mod Matrix (Osc /
Phase). Note that this modulation not only affects the starting-phase but
continuously changes the phase which is good for certain sound effects.
The Phase is also shown in the waveform display on the left.
Spread
Next comes the Spread section which consists of 4 parameters. Spread
means that a single Oscillator is running multiple times with the voices
being detuned against each other for a fatter sound. This is also called
(polyphonic) Unison. The Spread label indicates whether or not Spread is
active, if its lit (light blue) Spread is active, if its grey, its inactive. Its no
switch, if Spread is active or not is determined by the Spread Detune
parameter.
For Spread again the just described Phase parameter has an important
meaning: When set to Free, the Unison starts at a random deviation of all
