Pulse is a Pulse with selectable
asymmetric
pulse width. This is the type of pulse waveform found in most
analog synthesizers. At 50% Shape setting, the signal is a perfect Square, at 75% a Pulse with 25%/75%
pulse width and at 99% a Pulse with 1%/99% pulse width. When the Shape is modulated with negative
values, the signal is “mirrored”.
SymPulse is a Pulse with selectable
symmetric
pulse width. At 50% Shape setting, the signal is a perfect
Square, at 75% a Pulse with 25% symmetric pulse width and at 99% a Pulse with 1% symmetric pulse
width. When the Shape is modulated with negative values, the signal is “mirrored”. See also

With the Shape Oscillators A and B it’s very easy to
create an “analog style” sound without using a Filter.
Connect the OscShpB module according to the pic-
ture, select the Sine1 waveform and assign the Shape
knob to an
A
SSIGNABLE
K
NOB
. Play on the key-
board and turn the
A
SSIGNABLE
K
NOB
to increase
the overtone content. The effect is very similar to
running a sawtooth wave into a filter and increasing
the Filter Cutoff Frequency value.

The Dual Oscillator actually contains
two oscillators plus a sub oscillator. Two
main oscillators with Pulse and Saw-
tooth waves and a sub oscillator with a
Square wave. The Pulse and Sawtooth
oscillators have the same pitch whereas
the sub oscillator pitch is one octave be-
low. The pulse width of the Pulse oscillator can be modulated as well as the Phase of the Sawtooth signal.
The Soft button affects the sub oscillator and reduces the overtone content of its signal. See also
