Detune
-64…+63
Fine-tunes the oscillator in steps of 1/128th of a semitone. The audible result of detuned oscillators is
a Chorus or Flanger effect. Use a positive setting for one oscillator and an equivalent negative setting
for another.
A low value of
±1
results in a slow and soft Flanger effect.
Mid-ranged settings of
±5
are perfect for pads and other fat sounding programs.
High values of
±12
or above will give a strong detune that can be used for accordions or effect
sounds.
FM
0…127
Sets the amount of frequency modulation that is applied to the oscillator by the selected
FM source
in the Oscillators Edit menu. The sound will get more metallic and sometimes even drift out of tune,
especially if Oscillator 2 is used as FM Source for Oscillator 3 and
Sync
is activated. To avoid
unusable detune, use a triangular or sine waveform for the FM Source.
If you want to bias
FM
over the keyboard so that higher notes aren’t modulated as strongly as
lower notes, use the
Standard Modulation Matrix
and apply
Keytrack
to the respective
oscillator FM with a negative amount.
To change the amount of
FM
dynamically, use the
Fast Modulation Matrix
or
Standard
Modulation Matrix
to apply an
Envelope
or an
LFO
to the respective oscillator FM with
positive amount.

This parameter may also be found in the
Oscillator Edit Menu
for the sake of completeness.

FM
requires a lot of CPU Power, which can lead to decrease polyphony.

Pulse / Saw / Tri / Sine / Alt1 / Alt2
Sets the type of waveform to be generated by the Oscillator. The parameter is called
Shape
instead of
“waveform”, because it doesn’t necessarily set only one waveform, but sets a specific oscillator model
that could produce a number of waveforms depending on other settings. A good example for this
behaviour is the
Pulse
shape. However, the term “waveform” is used interchangeably throughout the
manual. The following shapes are currently available:
Pulse
(variable Pulse Width)
Sawtooth
Triangle
Sine

Off
disables the selected oscillator for the purpose of increasing Polyphony. Please read the
chapter "Dynamic performance management" on page 24.
•
Pulse
selects the pulse waveform. A pulse waveform with a pulse width of 50% has only
the odd harmonics of the fundamental frequency present. This waveform produces a
hollow / metallic sound. If the Pulse waveform is selected, the parameters
Pulsewidth
and
PWM
are used to change the pulsewidth of the waveform. Furthermore, the modulation
