OSCILLATOR 2 – FRONT 
PANEL
SHAPE Same as OSCILLATOR 1; see 
paragraph above.
WAVE SEL/PW Same as OSCILLA-
TOR
 1; see paragraph above.
SEMITONE Determines the inter-
val between the second oscillator 
and the first oscillator: Control 
range +/-48 semitones, assigned in 
semitone steps.
DETUNE Detunes the second oscil-
lator relatively to the first. With 
this parameter, you can dial in 
everything from slight deviations 
in pitch to major fluctuations 
between the two oscillators.
SYNC Synchronizes the second 
oscillator with the first: The SYNC 
function forces Oscillator 2 to 
interrupt its wave cycle and restart 
it at the same time as Oscillator 1 
starts its cycle. The effect of this 
measure is that pitch deviations 
and intervals are no longer audible 
as such; what you hear are tonal 
modifications: Repeated interrup-
tion of the Oscillator 2 wave cycle 
generates new tonal spectra with 
a great deal of overtone content. 
The tone of a given spectrum can 
be influenced via the SEMITONE 
knob, among other control fea-
tures.
