µMIDI Manual
Overview
The µMIDI provides all the essentials to control and sync your Eurorack modular from your
computer, iPhone/iPad, or hardware MIDI device with a minimum of fuss. No menu diving or
configuration scripts, just two buttons. The connectivity, feature set, and compact size make the
µMIDI ideal for integrating your modular with the rest of your rig while not taking up too much
space in your case.
The upper clock section features a dedicated 16th note clock output ideal for synchronizing a
Eurorack sequencer like the Metropolis. A second clock output with selectable divisions can be
used when difference sync events are needed. The run and reset outputs can be used to reset
your Eurorack sequencers in tandem with any external sequencer or DAW.
The lower half of the µMIDI gives you everything you need to control a single voice synth via
MIDI. Just connect either a USB or DIN MIDI cable to the module, LEARN a channel, and start
playing.
Future firmware updates over USB are made easy with the Firmware Updater software.
Features
● High speed ARM processor for low latency & jitter.

Installation
Intellijel Eurorack modules are designed to be used with a Eurorack-compatible case and power
supply.
Before Your Start
Before installing a new module in your case you must ensure your case’s power supply has
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 you have enough free space (hp) as well as free power headers in
your case to fit the new module.
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.

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:
