3.1 Master Clock Module Overview
The master clock module is central to Pulsar-23’s timing and tempo. The
role of a clock is important in modular based systems to ensure all
functions operate in time together. Timing pulses are sent to enable this
synchronisation across functions and can also be used to trigger drum hits
and events. Multiple divider points are available for patching the clock. The
clock is also tightly linked to operation of the loop recorder.

Item Function Label Control Description
1 Clock CLK Pin Operates as clock generator output when switch is in
INT or MIDI position. When switch is centred, clock
recognises this pin as an external input to the clock
which controls the clock dividers and looper recorder.
2 Dividers Various Pin Output pins for the binary clock dividers. Ideal for
driving drum triggers and creating patterns and
controls. The 8 labels indicate note duration from; 16,
8, 4, 2, 1, 0.5, 0.25. Array represents looper length.
3 Reset RST Button Resets the clock divider array and therefore the looper
recorder is reset to the start and is synchronised to
the clock. Press before loop recording to ensure
synchronisation between looper and clock dividers.
4 Clock
Source INT
MIDI Switch Selection of clock source between internal clock
generator - left, external MIDI source - right and when
set to centre, internal clock is disabled / stopped and
CLK acts as an input for an external pulse.
5 Clock
frequency MOD Pin Connection for external control and modulation of the
clock frequency.
6 Amount of
modulation AMT Knob Amount of modulation CV applied to the MOD Pin
input for frequency control.
7 Tempo TEMP Knob Sets the clock generator frequency between 1-200Hz.
This effectively determines tempo and looper length.
8 Tempo
indicator LED LED indicator which flashes in time with tempo
frequency, once per quarter plus bright flash at the
loop start. LED is green.
