1. Disconnect your cabinet from the mains.
2. Triple check the power cord polarity. Connect the cable from
EXPANSION_PORT (Muxlicer) to TO_MUX (MEX). Check the picture below to
align the connector according to the polarity (marked on the PCB).
3. If you plug the module backwards you might burn it out and
unfortunately this is not covered by the warranty.
4. If you have any questions about this product feel free to contact us:

MEX is an expansion module for Muxlicer that adds an extra 8-step Gate sequencer to Muxlicer.
The module is powered directly from the Muxlicer’s expansion port located at the back of the module (see connection diagram
above).
MEX counts with a very straight forward interface based on ten elements: eight three position switches (to
select the mode for each step), a Gate Input and a main Out for the Gate signals.
Several MEX can be connected
in series via the THRU connector
at the back of the module.
To connect it, use the provided
cable keeping in mind that the red
lines must match with the white
lines on the silkscreen.

Internally, MEX is connected to Muxlicer’s Internal Clock. The Gate sequence on MEX follows the
same steps present at Muxlicer, but thanks to MEX selectable modes per step, we can create
different variations of the original sequence. Having this in mind is very important to understand
well the three functional modes of MEX, let’s take a look to them.

Right position (All Gates Mode): on this mode the selected step will fire the same signal present
at its related Muxlicer Gate output. If you have multiple Gates per step selected on the Muxlicer (Gate
Amount parameter) you will get the exact same amount of Gates at MEX output. If all the steps are
set at the Right position, you will get an exact copy of Muxlicer All Gates output at MEX Out.
Center position (No Gates Mode): if a step is set at the center position of the switch, no Gates
will be fired when the sequence reaches this step.
Left position (Pass In Mode): in this mode, the selected step will pass the signal
present at Gate In. By default this jack is normalized to Muxlicer’s Clock Out.
If the Clock Out on Muxlicer is set as a multiplication of the Internal Clock, several
Gates will be fired at the output. Otherwise if Muxlicer’s Clock Out is set as a
division of the Internal Clock some steps will be skipped.

As internally Gate In works as a comparator, you can also plug
any type of signal on it and get interesting results. In the example
below, an analog sine wave is plugged at Gate In. It results in a
Gate with a length equal to half of the sine wave period.
Friendly reminders:
- The Muxlicer can output the clock out even when its sequencer is stopped. This can be set by holding the
Play Switch up for three seconds when the Muxlicer is stopped.
Set it as your taste if you prefer to keep running the Mex when the Muxlicer is stopped.
- The non Quadratic divisions can be removed on Muxlicer's Clock Output, which will have effect on Mex also.
To do that, turn on the Muxlicer while holding up the Play Switch.
To revert it just repeat the process.
