Crush:255 Phs:0 FmDp:20 PMod:2
„Crush“ - Bitcrushing reduces the bitrate of the oscillator signal. This
parameter also reduces the sampling frequency and adds some aliasing
to the oscillator signal at higher values. If you are running an oscillator at
a very low frequency, high crush values create nice modulation patterns.
„Phs“ - Phasestartpoint sets the position of the waveformstart at a note
on event. If set to zero, the phase start is freerunning. Every note starts
the oscillator at another position of the waveform. However - sometimes,
especially at low sine basses or percussion sounds one needs a fixed
startposition to avoid pops and clicks or to control the transients.
„FmDp“ - (Frequency modulation depth of Oscillator 4 as the modulator)
the depth is dependent also from the Modulation wheel. Allows realtime
controllable Vibrato and FM FXs.
„PMod“ - (Pitchbend modulation depth) sets the Pitchbend range in
halftones.
Tip! Menupage 3/4 of the VCO pitch menu offers that parameter for all
oscillators at once.
The noise source is an additional sound source of the hybrid engine. You can
use the noise as a continuous signal or as an enveloped signal triggered by note
events. Page 23/27 controls the enveloped noise source and Page 24/27 controls
the continuous noise signal.

„FB“ - Filterbank level controls the noise level for the fixed filterbank.
„LP“ - Controls the noise level for the 24dB Lowpass.
„MM“ - Controls the noise level for the multimode filter.
„Bus“ - controls the noise level fed directly to the output bus.
The keyboard level scaling allows for changing the oscillators volume
depending on the key played.
