LFO knob
Sets the rate of the LFO cycle
This is also the master clock for the PULSE
modulations.
SHAPE knob
Adjusts the waveform for modulating the
filter with the LFO cycle
2-4-8-16 knob
Choose the number of PULSE modulations
per LFO cycle. This also sets the
Clock Out
frequency.
LFO switch
Enables filter modulation by the SHAPE knob
SHAPE switch
Controls the direction of the filter sweep from
the SHAPE knob
PULSE knob
Controls the depth of filter modulation from
the 2-4-8-16 knob. The waveform is a
square wave. The indicator LED ashes with
the timing of the PULSE waveform.
The Pulse LFO waveform is created by a
phase-locked loop (PLL). The PLL tracks the
LFO and multiplies its frequency by 2, 4, 8, or
16 times.
When you adjust the LFO rate, the PLL does
not track the changes instantly, but takes time
to lock on. The slower the LFO is, the longer it
takes the Pulse to lock on the new tempo.

To synchronize the LFO with other analog
equipment, patch
Clock Out
from this unit to
the Clock In or Sync In on an external
sequencer.
This method only applies to external
sequencers with analog square wave Clock In
** This unit does not take Clock In from an
external sequencer.
To approximately match the tempo of this pedal to an
external rhythm, by ear:
Turn PULSE knob full counter-clockwise
Turn SHAPE knob full counter-clockwise
Turn LFO switch ON
Beat-match the click from the LFO with the external
rhythm, listening carefully while turning the LFO
knob in small increments.
When you have got it close enough, wait for the
Pulse LED to stabilize, then turn up the PULSE knob.
