Clock O’Pawn
The Clock O’Pawn is a useful clock sourcing device that
performs as your system’s true chef d’orchestre. Its transport
section lets you start, stop, and reset connected instruments
which are synchronised to an intuitive internal clock source or
dancing along with your analogue and MIDI equipment. If you
get bored by a metronomous clock, turn up the swing function
and the maestro will lead with a nice shuffled feel !

The Clock O’Pawn requires a standard 2x5 pin eurorack power
cable. Make sure the red stripe on the cable matches the -12V
side of the Clock O’Pawn power header.
Installation
CLK1 [3] produces a 1/16th note clock signal, which is
generated either by internal (BPM / Tap Tempo) or external clock
sources (analogue clock / MIDI).
The BPM potentiometer [A] allows fast access to a broad range
of BPMs. To tap the tempo, hold the CLK2/EXT button [E] and
tap in 4 quarter notes on the Play button [G]. Tap tempo
acquisition is indicated by a blinking EXT LED [B].
External clock source synchronisation (indicated by the EXT
LED) is accessed by holding the CLK2/EXT button [E] for 4
seconds. The module syncs to a 4 PPQN clock received in the
CLK IN input [1] or to a MIDI clock signal received in the MIDI IN
input [2]. The MIDI clock has priority over the analogue clock.
Setting the BPM
Transport & Reset
The Play [G] & Stop buttons [F], as well as MIDI “play” and
“stop” messages, allow to start and interrupt the generated clock
signal. Besides, each of these actions generates a pulse at the
RST output [4]. When the Play button is pressed while the clock
is being generated or when a MIDI “pause” message is received,
the clock is paused without producing a reset pulse. By holding
the Stop button and pressing the Play button, the user can send
reset triggers while the clock is running.
Depending on its state, the CLK2 output [5] produces an
alternative clock signal to CLK1. It can be set through the
CLK2/EXT button [E] to :
• Not be affected by the swing function (CLK2 LED off)
• Not respond to the transport section (CLK2 LED on)
• Both of the above (CLK2 LED blinking).
Second output
Turning the Swing potentiometer [D] adds shuffle to the clock
signal. This allows to obtain a feel between binary and ternary,
as performed by jazz musicians. When the potentiometer is
turned fully clockwise, the module puts out a triplet clock.
Swing
The module works with a TRS MIDI
cable for which two standards exist.
The two jumpers on the back of the
module select which standard is used.
Placing them horizontally sets the
module to TRS MIDI A standard, and
vertically to TRS MIDI B.
