VOLUME
This knob has two functions:
In the left half of its control range up to the
center position (MIDI value 64), OSC VOL deter-
mines the master volume of the three oscillators
prior to the filter section input. The Noise Gen-
erator and the Ringmodulator are not affected
by the master volume knob OSC VOL. Their lev-
el is controlled separately in the OSCILLATOR
EDIT menu (see appropriate section).
In the right half of the control range from the
center position to the far right, OSC VOL in-
creases the saturation intensity (Gain) for the in-
put of the SATURATION stage (see appropriate
section); however this adjustment is compen-
sated post-SATURATION stage so that when
you adjust the gain you are not actually increas-
ing the volume, only manipulating the tonal
spectrum in terms of saturation. The intensity of
the remaining DSP effects available in the SAT-
URATION Stage is controlled via the OSC VOL
knob.
PHASE INIT
This feature lets you select the oscillator phase
position at the start of a note. At a value of 0, all
oscillators oscillate freely much like in a tradi-
tional analog synthesizer. At values of 1 and
higher, Oscillator 1 starts the note with a phase
angle of 0, whereas the phase position of the
second oscillator is shifted increasingly at as-
cending values. The Phase position of oscillator
3 is shifted to the opposite direction. With this
parameter, the attack phase of every note is
identical, which is a handy feature for program-
64≤
ming drums and percussive sounds. In con-
junction with Oscillator 3 and PHASE INIT, you
can create prominent overtones that are initiat-
ed at the beginning of a note.

RINGMODULATOR

VOLUME
The ring modulator multiplies the output of both
oscillator 1 and 2 to create interesting sounds
with rich enharmonic overtones. These over-
tones are highly dependent on the frequency
coherence of both oscillators and it's wave-
forms. The frequency coherence can be
changed, for instance use the OSC2 SEMI-
TONE parameter. If the RINGMODULATOR
VOLUME is zero, the ring modulator is switched
off. OSC VOL does NOT affect the ring modula-
