•
Gaussian mode uses a gaussian distribution on
the volume of the oscillators, which can be fine-
tuned by the amount parameter.
•
Alternate mode lowers every other oscillator in
volume when changing the amount parameter.
•
Random uses a random tuning for all oscillators,
whenever a new key is pressed.
Semi
The control labelled SEMI adjust the coarse tuning
of the oscillator stack, in semitones. The range spans
+/- 36 semitones. A larger range can be obtained by
using the modulation matrix, if required. This will be
covered in chapter 4.
Fine
This parameter adjusts the fine tuning of the oscilla-
tor stack in cents. A value of +/- 100% corresponds
to half a semitone.
Detune
When two or more oscillators are active in the stack,
the detune parameter allows to spread their pitch
around the center frequency.
Spread
When two or more oscillators are active in the stack,
the SPRD knob allows to spread the oscillators in the
stereo field, around the center. Turned fully left, the
oscillator stack will be mono.
Reset
When reset is enabled, all oscillators in the stack start
at the same initial phase (by default zero, this can be
changed in the modulation matrix). Setting the initial
oscillator phase can be useful to obtain better control
of the transient of a sound, for instance. When using
more than one or two oscillators, note however that
reset will create strong phasing effects. It is thus usu-
ally better to keep reset turned off when using multiple
oscillators.
4.2.2 Synthesis types
Three different synthesis types, Virtual-Analog (VA),
Wavetable (WT) and Frequency Modulation (FM) are
available per oscillator. When using more than one
voice, it is furthermore possible to specify different
types for different voices.
