When you turn the PATH around, you should see the module as it is on the left illustration. Connect your power
header to the 10 pin connector on the bottom. Pay attention to the orientation of the cable, the RED STRIPE should
be on the top (next to the white marking)!

By doing otherwise you can potentially harm the module
or even your whole system! Power off your Eurorack system and connect the other end of the cable to the power
source, here also pay attention to the PSU manufacturers
instructions!

With the three pin header you can turn on or off the jack
lights. Top position is off, bottom is on. Turning on the
jack lights draw about 75mA more from the +12V rail.

04. USE
PATH consists of two 4:1 switches or one 8:1 switch.
1.
You can use it in two ways regarding the switching:
1. Insert signals in the 4 I/O jacks and switch between
them so that the selected signal comes out on the
bottom I/O jack.
2.
2. Insert a signal in the bottom I/O jack and you can
route the signal to different inputs via the four I/O
jacks.
The currently selected I/O is indicated by the LED next to
it RED for CH1 and GREEN for CH2.
5V is normalized to the COM I/O jacks so that when there’s
no jack inserted, the I/Os can be used as gates
05. CV/TRIGGER INPUT
Pressing the channel button switches between CV/trigger input modes.
When the channel LEDs are unlit it means that the channel CV/trigger input expects triggers. On the rising edge
of a trigger it’ll step to the next I/O channel.
When the channel LED is solidly lit, it means the channel
CV/trigger input expects CV between 0-5V.
05. CV/TRIGGER INPUT
CV is split between the available steps set in the sequence
length page, meaning that if there are 4 steps available,
the CV will change channel every 5/4=1.25V.

06. RESE T INPUT
Trigger mode:
On the rising edge of a trigger in the reset input the sequence goes back to step one.
CV mode:
On the rising edge of a gate in the reset input the current
CV is held on the value it currently is.
07. SEQUENCE LENGTH
Hold the channel button until it starts blinking.
The available steps are lit by the channel color. Pressing the button repeatedly cycles through 2-4 steps or in
chain mode 5-8 steps.
Long press the channel button again to exit this mode.
08. DIRECTION
Hold the channel button, first it starts blinking, then if
you keep pressing it, it’ll start blinking faster, now you
can release it.
FORWARD
BACKWARD
PENDULUM
RANDOM
This mode determines the step direction of the channel,
you can cycle through the directions by repeatedly pressing the channel button. The selected direction is indicated
by the channels’ color on the steps LEDs:
1. Forward
2. Backward
3. Pendulum
4. Random
Long press the channel button again to exit this mode.
09. CHAIN MODE
BUTTON
CV/TRIG INPUT
RESET INPUT
Press both channel buttons at once, now the two channels
are one and this group is controlled by the CH1 controls
(Button, CV, Reset).
The COM I/O of the 8:1 switches is the CH1 COM I/O jack.
If you want to split the channels again, just press the two
buttons at once.

10. NOTE
Due to the fast switching, pops can be heard when audio
is being switched.
