• Para-4 (only OSC 1) ist he same as Para-8. But two
oscillators per note are used. This will reduce the
polyphony to four voices. You can set up pulse-
width, pitch and fade individually.
w
Keep in mind: When Para-4 is selected as Shape
you cannot use OSC 3. This oscillator is not ac-
cessible then.
• X3-PWM (only OSC 2) creates a PWM crossmodu-
lation. Crossmodulation is a XOR combination of
the waveshapes of OSC 2 and OSC 3 which can
be used for creating very complex sounds with un-
harmonic frequency proportions.
• X1-PWM (only OSC 2) creates a PWM crossmo-
dulation. Crossmodulation is a XOR combination
of the waveshapes of OSC 2 and OSC 1 which
can be used for creating very complex sounds with
unharmonic frequency proportions.
w
Although Oscillator 1's or 3's square waveshape
is used for crossmodulation, it does not mean that
this square waveshape must be used as the
source signal. Because the crossmodulation is pu-
rely internal, you can select another waveshape
for Oscillator 1 or 3 if you so desire. Please note
that you can also modulate Oscillator 2's pulse-
width at any time. Additionally, you can switch
synchronization on and off independently.
• EXT (only OSC 3) switches off OSC 3 and enables
the external audio input for routing its signal
through the Pulse 2 synthesis path.
w
Please keep in mind, that an incoming signal can
get to the output section only when the VCA en-
velope is triggered or the VCA is open. This
means that the volume envelope ENV A has to
be started by an MIDI note. This can be achieved
by playing on a keyboard or by activating the
built-in arpeggiator.
•
FB (only OSC 3) creates a feedback from the drive
output back to the mixer. Depending on the filter
settings this can create interesting resonance ef-
fects that cannot be realized with the regular Re-
sonance
parameter.
