1. Disconnect your cabinet from the mains.
2. Triple check the power cord polarity. The coloured line on the cable
(pin number one) is the -12V rail.
3. If you plug the module backwards you might burn it out and
unfortunately this is not covered by the warranty.

Muxlicer is an eight channel, CV addresable bidirectional analog switch and gate generator.
It is designed with a high "function per HP ratio" philosophy, to have maximum flexibility
in minimum space. It is divided in three main blocks:
1. Digital Step Controller
Featuring Tap Tempo, Voltage controlled address
and two on board clock dividers/multipliers (one
for Clock IN and one for Clock Out).
2. Gate Generator
With independent Mix and EOC outputs and
voltage controlled repetition and behaviour.
3. Analog Switch (a.k.a Mux/DeMux)
Each I/O can pass analog or digital signals in
either direction.
.1
WITH THIS THINGY INSTALLED IN YOUR RACK YOU CAN:
* Route any modular audio or CV signal from one IN up to eight OUTs or viceversa.
* Generate CV and Gate signals, being able to work as a Sequencer.
* Cut audio signals in rhytmical slices with independent volume.
* Chop different audio signals in a rhytmical way.
* Generate complex CV/Gate patterns from any audio or CV moving signal.

ADDRESS KNOB/CV IN
Address CV IN and its associated manual control "Address Knob" sets the active step either
via voltage or manually. At 0v or Run position, the module plays the entire sequence from
step 1 to 8. But when its in another value than 0 Muxlicer will jump to a step relative to
the sum of both parameters.
It works in a synchronous way, so it will only work during playback, and will always wait
for the next clock pulse to react.
With the Address knob fully anticlockwise, CV ranges goes from 0 to 10v. With the pot at
the middle CVs go from -5v to 5v, and with the knob fully clockwise -10v to 0v will be
accepted. Other voltages are ignored and don't represent any danger for the module.
The address knob moves the count from 1 to 8 (clockwise). The address CV moves each
step in an equally voltage/step relation.
5v CV in is also possible by changing the CV range switch (The small switch from the back
of the module).
.2
You can use this Input to create random sequences or
unique ways of counting. Just send any complex CV
signal to Address IN and watch the sequence. Muxlicer
is always synchronized to the rising edge (even audio
rates) so with any signal you use you will always be in
sync.
PLAY SWITCH
Play Switch is momentary and has two positions (up click and down click):
Down click. Has dual
functionality. It Works as
“Manual Reset” during
playback and as “One Shot
Play” during stop. Manual
reset will return the count to
the step 1 regardless of any
other parameter. One shot
play will start the count, and
stop always at step 8. A down
click before One Shot play
will reset the count to the
Up Click. Works as “Start/
Stop”. One click and Muxlicer
will start the count from left
to right, beginning always
from the step 1.
With a second up click, it
stops at the current position.

RESET/ONE SHOT IN
This input has dual functionality (exactly the same functions as Play switch Down click). It
Works as “Reset IN” during play and as “One shot play IN” during stop.
During play: When a trigger or gate is
present the count will be reset to the step 1,
independently of any other parameters.
Connected Gate outs to this input limits the
amount of steps that Muxlicer counts.
During stop: This input will start a “One
Shot” cycle. Muxlicer will count until 8 then
stop. Use this to generate gated arpeggios or
(together with the EOC Out) chain more than
one muxlicer in series. If a second trigger is
received before the count is finished, it will
reset to step one.
SPEED DIV/ MULT ENCODER
This encoder has four different functions:
1. Tap Tempo
Tap this button twice and the tempo will be set at the speed
of the interval between these two taps. If you tap more than
twice (in a short time) the time between them will be
averaged to improve timing precision. Tempo adjustments are
stored in nonvolatile memory so it remains even when the
device is turned off.
2. Count Speed
Turning the encoder will always change the speed. When the
module works with the internal clock it changes the tempo.
When the module works with an External clock it divides or
multiplies the incoming clock.
3. Clock Out Div/Mult
Holding the encoder down and turning it the same time will
divide or multiply the Clock Output. Max rate. /16 (div) x16
(mult)
4. CV Range
Holding the encoder down and pressing the Play Switch Up or
down at the same time (without releasing the encoder), will
adjust the range of the CV at Com I/O. Longer holds of the
Play Switch will increase or decrease the CV Range drastically,
while shorter presses will change the value in small
increments.

CLOCK IN
Synchronize Muxlicer with an incoming clock signal. Muxlicer clock signal will synchronize
to the external clock falling edge and will advance an amount of steps depending on the
“Div/Mult” setting. Muxlicer automatically detects when something is plugged to this IN
switching from Internal to external clock. Every time that a cable is plugged to its Input,
Muxlicer resets the "Div/Mult" setting to 1/1.

GATE MODE
This knob and its associated IN, controls Gates behaviour. Moving the knob clockwise (or
adding CV at the CV IN) gates will change behaviour on the next step:
1. No Gate
2. Gate = Step Time
3. Half Step Time
4. Two Gates per Step
5. Three Gates per Step
6. Four Gates per Step
7. Five Gates per Step
8. Six Gates per Step
9. Seven Gates per Step
10. Eight Gates per Step
Turning On the module while
holding down the Play Switch
removes all the steps from
Gate Mode that are not
Quadratic (1, 3, 5, 6, 7)
To come back to normal Gate
behaviour just repeat the
procedure.
Gate Mode IN is normalized to 10v so the knob acts as a manual control when no CV is
present. When CV is present the Knob acts as an attenuator. 10v CV are accepted, but most
CLOCK OUT
Outputs the clock (either internal or external) divided or multiplied by an entire number. By
default it initializes after Play or Play One shot, and stops when Muxlicer stops. If you
want the clock out signal to always keep running even if you stop the sequence, hold the
Play switch up for three second while the module stopped (you will see the Clock led
frozen for one second). Turning On the module while holding up the Play Switch removes
all the steps from Clock Out that are not Quadratic. This can be repeated to re-enable
the steps that are not Quadratic.
EOC (End of Cycle) OUT
Outputs a short trigger when the count reaches the
end of step 8. It works only during play and not
if step eight is reached with Address IN. This is
useful for chaining more than one Muxlicer in series
or to trigger any other event like envelopes.
GATE OUTS
Output gates each
time the associated
step is activated
depending on the
Gate Mode Knob and
the corresponding CV.
ALL GATES OUT
Outputs a digital sum of all the
gates (logical OR)
GATE LEDS
These LEDs blink always when
a Gate is active. They indicate
also which step is active at
that time.

COMMON I/O
Is the main common Input/Output. Through this jack you can either send a signal to
the Mux I/Os or receive a signal from them (Depending on how the module it is
connected). It is also used as CV Out when nothing is connected to “All IN” or “Mux I/Os”.
Use this output as CV out when using Muxlicer as step sequencer (see later).
ALL IN
Any signal plugged to ALL IN will
go to all the “Mux I/Os” that don't
have any other signal plugged on
them.
All in is there to send the same
signal to any number of Mux I/
Os.
Imagine you want to send a signal
to the Steps 1,2,4,5,6 & 8. and a
two more signals to 3 and 7
respectively. You just need 3 wires
for this: plug the first one to All In
and the other two to 3 and 7 Mux I/
Os and you are done!
All In is normalized to a Voltage
(selectable by the user), so if
nothing is plug to this IN,
Muxlicer acts as normal step
sequencer. (Explained in Speed Div/
Mult encoder / CV Range Section)
MUX I/Os
Mux I/Os are (together with Common I/O) the
main connections of Muxlicer. Like common I/O,
they are reversible. That means, depending on
how the module is connected, you can either
send eight different signals to the “MUX I/
Os” to output as one at the "COMMON I/O", or
receive one signal at the "COMMON I/O"
outputed to each of the 8 "MUX I/Os".
The eight Mux I/Os are normalled to “All In” jack,
so any signal present at this input will go to all
of them. (see ALL IN Section)
LEVEL FADERS
These faders attenuate the signals that goes from the “Mux I/Os” to the “common I/O” (or
vice versa). When no signal is plugged to either “Mux I/Os” or “All IN” they act as CV Levels.
This is because they Attenuate the default All IN voltage.
WHAT IS AN ANALOG SWITCH?
An analog switch is a switching
device capable of switching or routing
analog signals. In the case of
Muxlicer the switch is reversible, this
means that you can send 8 different
signals to 1 destination or in the
opposite way, send 1 signal to 8
different destinations.

SLICING SIGNALS
With Muxlicer, you can slice any modular signal in the onboard analog switch circuit. Just plug a
few signals into the Mux I/Os that you want, the COM I/O to your Out Module and press the play
switch. Now you can listen to a sequence with your signals sounding on their corresponding steps.
If you plug a signal to All In input, it will be present in all the steps of the sequence except the
ones that already have a signal. Finally, you can control the level of any signal with its
corresponding level fader.
BASIC SEQUENCING
Without signals present in the Analog Switch, the module works as a powerful 8 step Gate/CV
sequencer with selectable CV range and gate retriggering. Just plug the COM I/O to the V/Oct input
of your oscillator and the All Gates output to the gate/trig input of your voice envelope and you're
ready to go. Set the note of each step with its corresponding level fader and adjust the range of
the CV by holding down the encoder and at the same time pressing the Play Switch up or down.
Also you can control the retriggers of the gates via the Gate Mode pot and its associated CV
input.

ADVANCED GATE SEQUENCER
One of the most cool features of Muxlicer is the posibility of being a complex gate sequencer with
voltage controlled retriggering for each step. To do that, just plug the COM I/O to Gate Mode CV
Input and the All Gates Output to the Trigger/Gate Input of your module. Put the CV range of
Muxlicer to maximum and press the Play switch. Now you can adjust the amount of retriggers in
each step manually, with the sliders, or via CV, plugin CV signals to Mux I/Os. If you want to
reduce the maximum number of retriggers on the steps just play with the CV range till you like
the result.
