Tetrapad Manual
Installation
Intellijel Eurorack modules are designed to be used with a Eurorack-compatible case and power
supply. We recommend you use Intellijel cases and power supplies.
Before installing a new module in your case, you must ensure your power supply has a free
power header and sufficient available capacity to power the module:
● Sum up the specified +12V current draw for all modules, including the new one. Do the
same for the -12 V and +5V current draw. The current draw will be specified in the
manufacturer's technical specifications for each module.
● Compare each of the sums to specifications for your case’s power supply.
● Only proceed with installation if none of the values exceeds the power supply’s
specifications. Otherwise you must remove modules to free up capacity or upgrade your
power supply.
You will also need to ensure your case has enough free space (hp) to fit the new module. To
prevent screws or other debris from falling into the case and shorting any electrical contacts, not
leave gaps between adjacent modules, and cover all unused areas with blank panels. Similarly,
do not use open frames or any other enclosure that exposes the backside of any module or the
power distribution board.
You can use a tool like ModularGrid to assist in your planning. Failure to adequately power your
modules may result in damage to your modules or power supply. If you are unsure, please
contact us before proceeding.
Installing Your Module
When installing or removing a module from your case
always turn off the power to the case and disconnect the
power cable. Failure to do so may result in serious injury
or equipment damage.
Ensure the 10-pin connector on the power cable is
connected correctly to the module before proceeding.
The red stripe on the cable must line up with the -12V
pins on the module’s power connector. The pins are
indicated with the label -12V, a white stripe next to the
connector, the words “red stripe”, or some combination of
those indicators.

Tetrapad Manual
Most modules will come with the cable already connected but it is good to double check the
orientation. Be aware that some modules may have headers that serve other purposes so
ensure the cable is connected to the right one.
The other end of the cable, with a 16-pin
connector, connects to the power bus board of
your Eurorack case. Ensure the red stripe on
the cable lines up with the -12V pins on the
bus board. On Intellijel power supplies the
pins are labelled with the label “-12V” and a
thick white stripe:
If you are using another manufacturer’s power
supply, check their documentation for
instructions.
Once connected, the cabling between the module and power supply should resemble the
picture below:
Before reconnecting power
and turning on your modular
system, double check that the
ribbon cable is fully seated on
both ends and that all the pins
are correctly aligned. If the
pins are misaligned in any
direction or the ribbon is
backwards you can cause
damage to your module,
power supply, or other
modules.
After you have confirmed all
the connections, you can
reconnect the power cable and turn on your modular system. You should immediately check that
all your modules have powered on and are functioning correctly. If you notice any anomalies,
turn your system off right away and check your cabling again for mistakes.

Tetrapad Manual
Overview
Tetrapad is a versatile, multi-dimensional, touch-sensitive control surface for Eurorack. Each
of its four pads use force sensing resistors to respond to both the vertical position of your
finger and its pressure. Four push encoders and a shift function give you even more tactile
control over your modular system.
Tetrapad operates in numerous modes — each of which configures the module to perform a
specific control task. Through these modes, Tetrapad becomes an 8-key keyboard; a voltage
storage device; or a 4-note chord generator. In its special Combo Mode, each pad can be
assigned a function independent of the other three pads, such as: a fader; a bi-polar fader;
an LFO; a dual switch; or a finger drumming pad. The chosen mode determines what type of
signal (CV, note, trigger, gate, etc.) is sent from each of Tetrapad’s eight independent
outputs, while its multitude of multi-colored LEDs keep you informed of exactly what’s
happening within each mode.
Each mode contains 12 memory slots for that mode, allowing you to instantly recall one of
12 different custom keyboards; one of 12 different voltage maps; one of 12 fader/LFO/switch
combinations; etc.
Tetrapad automatically remembers how you’ve configured each of its modes, and retains
these settings when powered off. By default, Tetrapad automatically saves these settings
every minute, or whenever you change modes. This makes Tetrapad ideal for live
performance, since you know it will always power up with your configurations intact.

Tetrapad Manual
1. Pads 1-4
Four identical touch strips, each of which is sensitive to both vertical position and finger
pressure. Depending on Tetrapad’s current mode, these pads can transmit trigger
signals, gate signals, quantized note values or real-time control voltages.
2. Level LEDs
Embedded beneath the surface of each pad is a 12 LED ladder. This ladder displays
different parameter values in different modes. When operating as a basic fader, the
LEDs represent the fader’s level; when operating as note triggers, they represent the
note assignment; when selecting modes, they display identifying mode numbers, presets
numbers, or Combo Mode animations.
3. Push Encoders 1-4
Each of the four pads has its own associated push encoder, which functions differently
depending on Tetrapad’s current mode. For example, in Custom Keyboard Mode, the
encoders assign note values for each output. In Voltages Mode, the encoders assign
voltage values to an output. Similarly, pressing the encoder has different functions
depending on the mode. For example, if you’ve assigned a fader to a pad in Combo
Mode, pressing an encoder latches that fader’s value. Not every function uses the
encoders, so please read each specific mode discussion to learn more.
4. Pad Status LEDs 1-4
Some modes use these LEDs to indicate a pad’s status. For example, they may indicate
whether or not a pad’s fader level is latched; or to which octave a note belongs.
5. Level Labels
This vertical column of text provides meaningful labels to each of the 12 vertically
stacked Level LEDs. On the right are note names, which indicate pitch when appropriate
to the selected mode. On the left are numbers 1-12 for indicating numerical values.
