Clanches is an 6 HP clock source and dual random gate. It is a modification of Olivier
Gillet´s module Branches.
The internal clock indicated by the LED located in the centre is normalled to both
inputs of the random gate. If there is an external trigger patched to one of the
IN jacks, this connection will be interrupted. The gate takes a trigger or gate as
an input and routes it to either one of its two outputs A and B according to a random
You can manually adjust the internal clock rate. A Switch changes the range from
slow over moderate to very fast.
The CV input gives you the opportunity to use control voltages in order to adjust
the clock speed. Any signal above 3V will vary the rate. If the signal drops below
3V the clock generator is forced to hold. This way you can generate very interesting
rhythms by just patching a random signal or LFO into the Clock CV. The internal clock
is furthermore supplied via the OUT jack.
The two manual controls P1 and P2 and their corresponding CV inputs change the probability
of a signal to be routed to one of its outputs. In extreme settings, the outcome
is no longer random causing the module to behave like a voltage controlled switch.
The two LEDs on top indicate which output of each channel has been selected to route
In contrast to the original Branches module the two toggle switches simple change
the behaviour if the P1 or P2 is set fully clock- or fully counter clockwise. If
you hold the button for 2 seconds once the signal will be routed to A and B alternately
with each incoming trigger. In normal mode the will just be routed to A (CW) or B
And yes…there is an actual airwire you have to solder on the top side of the Main
PCB. It is clearly marked, you have dedicated holes to solder the wire ends and you
won´t even see it on the finished module. As this PCB is very dense I had no choice
to avoid this little wire. This will be improved with a forthcoming revision though.
