INTRODUCTION
IXO is a simple, functional utility module that can help you access the MIDI and I2C
capabilities of other Eurorack modules, using 3.5mm TRS cables.
IXO is a cousin of our popular MIDIXO TRS MIDI breakout module.
Like MIDIXO, it can serve as a TRS MIDI breakout for lots of Expert Sleepers modules (like
disting mk4, disting EX, FH-2, ES-9, and General CV) and some other modules as well (like
the SDS Accord Melisma and SDS Sequarallel). Unlike its cousin, IXO also includes a
separate port that gives you access to the I2C protocol on modules like ER-301, disting
EX, and Teletype. It makes a great interface between those modules and controllers like
the 16n faderbank as well, giving you access to all those parameters through physical
faders – using either MIDI or I2C or even both at the same time.
FUNCTIONS
This module has two main functions:
1. By using the included 4-pin ribbon cable, IXO can extend modules like disting mk4,
disting EX, FH-2, General CV, ES-9, and some others – essentially adding MIDI input
and MIDI output jacks to those modules. The polarity on the input and output MIDI
jacks are each independently switchable to allow maximum compatibility with
your other gear.
2. By using included 3-pin ribbon cable, IXO adds an I2C jack to modules that use
that protocol, such as disting EX, ER-301, and Teletype.
You might connect all three of the ports to one module (eg: disting EX) to allow access to
both MIDI and I2C simultaneously. Or you could decide to use one IXO with multiple
modules. For example, by placing it between your disting mk4 and your disting EX, you
could use the IXO MIDI ports with the disting mk4 and the I2C port with the disting EX!
MIDI TRS
For as long as we can remember, MIDI has travelled over 5-pin DIN cables. Recently,
manufacturers of Eurorack-compatible gear have wanted to move to the slimmer, more
familiar, 3.5 mm cabling that we all know and love. But without a standard to guide them,
two kinds of MIDI over 3.5 mm TRS cables have appeared: MIDI TRS A and MIDI TRS B. If
you’ve got gear from Make Noise, Akai, or Korg, it works one way. Novation and Arturia do
it the other way. By using the polarity switches near the MIDI jacks on IXO, you can
essentially ignore this A vs B issue: if your module doesn’t seem to be sending or
receiving MIDI, you can just flip the appropriate switch! (Having the switch in the wrong
orientation will not cause any damage.)

I2C
I2C is a protocol that some modules use for communication – in addition to, or instead
of, MIDI. There is an excellent description of I2C on the lines forum, including a list of
modules that use the protocol and information about how to configure them. As you read
that page, keep in mind that IXO does not provide a powered bus – it is totally passive. A
powered bus may be needed for more complicated I2C networks that include several
modules communicating with each other. See the Example Configurations section for
some I2C use cases.
INSTALLATION
For MIDI Breakout Capabilities
1. Connect the included 4-pin ribbon cable to the 4-pin header on IXO
2. Connect the other end to a compatible module – ie: one with an optically isolated
4-pin header for MIDI in/out.Whichever module you are using, check its manual to
verify that you’re connecting the cable to the correct 4-pin header, since there may
be more than one. For Expert Sleepers modules, you will be likely be connecting
the cable to a header labeled GT2, GT3, or GT4. Note which color is connected to
pin 1 on IXO and make sure that same color is connected to pin 1 on your Expert
Sleepers module. If you connect it backwards, the MIDI input and output jacks on
IXO will be swapped – no damage will occur. If you have a module that requires a
different pin arrangement than Expert Sleepers uses, get in touch with us so we
can either help you modify the 4-pin cable accordingly or send you a cable to fit
your needs. (The SDS Accord Melisma and SDS Sequarallel fall into this category.)
For I2C Breakout Capabilities
1. Connect the included 3-pin ribbon cable to the 3-pin header on IXO
2. Connect the other end to a compatible module – ie: one with a 3-pin header for
SDA, SCL, and GND. While there isn’t really a standard for the order of the pins on a
module’s 3-pin I2C header looks like, everyone generally uses the same order. You
can verify that the pins match by looking at the SDA, SCL, and GND labels where
the 3-pin cable connects on both IXO and your other module. Again, if you find that
you need a different pin arrangement on the cable, please let us know.

OPERATION
MIDI Operation
Once IXO is installed as described above, the attached module will be able to send and
receive MIDI using the top two jacks on IXO.
1. Check your module’s manual to see what its capabilities are, with respect to
sending and receiving MIDI.
2. To send MIDI to the attached module, plug a stereo audio cable from a device that
sends MIDI to IXO’s input jack (the top one).
3. To get MIDI out of your attached module, plug a stereo audio cable from IXO’s
output jack to the MIDI input of a device that can receive MIDI.
If MIDI messages don’t seem to be making it through, flip the polarity switch near the
appropriate jack on IXO.
Some Expert Sleepers modules have a helpful “MIDI Thru” option. See the Example
Configurations section below for more information.
I2C Operation
Once IXO is installed as described in the previous section, the attached module will be
able to send and receive I2C messages using the bottom jack on IXO.
1. Check your module’s manual to see what its capabilities are, with respect to
sending and receiving I2C messages.
2. To allow I2C messages to be sent and received, plug a stereo audio cable from
IXO’s bottom jack to another I2C device.
I2C can be fussy. Here are some tips:
•Use cables that are not excessively long.
•If you have an I2C network with several devices on it, you may need a powered
bus. IXO is designed to allow communication between the module it’s attached to
and another I2C device.
•Check the Frequently Asked Questions section below for more help getting I2C to
work.
•Watch this 16n AtoVProject build video to see an example of IXO providing a path
for I2C communication between a 16n faderbank and a disting EX.

EXAMPLE CONFIGURATIONS
Example 1: Expert Sleepers
disting Mk4
with MIDI thru
This example uses the IXO MIDI jacks exclusively, to serve as a MIDI breakout for an
Expert Sleepers disting Mk4. The TRS MIDI output from a Beatstep Pro MIDI controller is
connected to the MIDI input jack on IXO, allowing it to send MIDI note and CC data to
disting. MIDI data sent from disting (eg: from algorithm H-5 Dual Euclidean Patterns) will
be sent to the connected O-Coast.
Note: If “MIDI Thru” is enabled in the disting settings, messages will be forwarded from
the Beatstep Pro to the 0-Coast, independent of what disting is doing at the time!

Example 2:
Accord Melisma
Despite the fact that the Accord Melisma by SDS Digital has a TRS MIDI output jack on its
front panel, IXO can serve as a separate set of MIDI input and output jacks for the
module. This adds the ability to merge MIDI messages as well (see the Accord Melisma
documentation for more information.) In the example below, a 16n faderbank is sending
MIDI CC’s to the Accord Melisma through IXO. The Accord Melisma is sending MIDI data,
through IXO, to an M-Audio MIDI interface and a computer running Ableton Live.
Separately, the Accord Melisma is able to send MIDI notes to a MIDI synth via the MIDI
output jack on its front panel.

Example 3:
disting EX
via MIDI & I2C
This example takes full advantage of disting EX’s MIDI and I2C capabilities. IXO provides
TRS jacks for MIDI input, MIDI output, and I2C. All functions can be used at the same
time. The ability to map controls from the Keystep Pro and the 16n faderbank to
parameters in disting EX, means that complex algorithms can be used and controlled
with knobs, sliders, and switches instead of relying solely on disting’s on-screen menus.
Again, if “MIDI Thru” is turned on in the disting EX settings, MIDI data will be passed from
the Keystep Pro to the Microvolt, regardless of what disting is up to.

Example 4: IXO serving two separate modules
In this example, IXO has its MIDI jacks connected to disting EX and its I2C jack connected
to a separate module entirely (eg: teletype or ER-301.)
In the diagram below, disting EX is being used to record multisamples from an analog
synth, as described in Expert Sleepers’ Autosampling via MIDI tutorial. Separately, scripts
on the monome teletype are able to read the positions of the faders on the 16n faderbank
via I2C.
