Conduit - MIDI Hub

Modes Of Operation

Conduit operates in two distinct modes: Standalone and USB MIDI
Interface modes.

MIDI hubMIDI hub

Standalone Mode

Conduit always operates in Standalone mode unless it is connected to
a computer via the USB-C port. This mode is used for distributing MIDI
data received at the DIN MIDI IN to the 1/4” TRS jacks and the DIN MIDI
OUT port. A common example of this is connecting a MIDI controller to
the DIN MIDI IN of Conduit which distributes the MIDI data out to the
1/4” TRS jacks and DIN MIDI OUT port.

(See Appendix 1 starting on page 19 for details.)

USB MIDI Interface Mode

Conduit enters USB MIDI Interface mode when it is connected to a
computer via the USB-C port. When USB is connected, Conduit will
expose each of the TRS jacks and the 5-pin DIN pair as an independent
MIDI device.

(See Appendix 2 starting on page 22 for details.)

DIN MIDI IN/OUT Ports

The 5-pin DIN MIDI IN port receives MIDI data from an external source
such as a MIDI controller or MIDI interface. Data is sent to all four 1/4"
TRS jacks and the DIN MIDI OUT port when Conduit is powered via
9V DC connection. All MIDI data sent back from 1/4" TRS connected
pedals is merged and sent to the MIDI OUT port when Conduit is not
connected to a computer via USB.

NOTE: When USB is connected, MIDI data received at the 1/4”
jacks from the connected pedals and from the DIN MIDI IN is sent
to the connected computer via its own independent MIDI port and
is no longer merged to the MIDI OUT port.

(See page 15 for details.)

(See page 15 for details.)

9VDC

Use an adapter with the following
rating: 9VDC center negative,
50mA minimum.

NOTE: Power supply is not
required when powered by
USB. The 9V can remain
connected without drawing
additional power.

1/4" TRS MIDI I/O Jacks 1-4

1/4" TRS MIDI I/O jacks 1-4 are capable of sending and receiving MIDI
data, which can be configured to work with a variety of different 1/4"
MIDI communication modes.

(See page 7 for details.)

1/4" TRS Jack Configurations

Out of the box, Conduit’s 1/4" TRS MIDI jacks are configured to work
with Strymon pedals with no further setup necessary. If you are
using Conduit with non-Strymon pedals, you may need to change the
configuration of one or more of the 1/4" TRS jacks.

(See page 8 for details.)

Press the SET button at any time to show the configuration state of all
1/4" TRS jacks:

GREEN = Tip Send (default setting — use for Strymon pedals)

Conduit sends MIDI at the TIP and receives at the RING.

RED = Ring Send

Conduit sends MIDI at the RING and receives at the TIP.

AMBER = Tip and Ring Send

Conduit sends MIDI at both the TIP and the RING.

NOTE: This mode can be used to connect
two pedals to a single 1/4" TRS jack.

(See page 13 for details.)

PURPLE = TRS TYPE A

Conduit sends MIDI OUT only with the RING as the current source
and TIP as the current sink.

NOTE: If you are using Conduit with non-Strymon pedals, visit

strymon.net/support/conduit to find out which 1/4" TRS jack

configuration will work with your specific pedals.

Connections – MIDI Distribution for a Pedalboard

The most common use for Conduit is for distributing MIDI messages
from a MIDI controller to pedals that are connected via 1/4" cables
(included) and 5-pin DIN MIDI cables (not included).

Follow the steps below when using Conduit to distribute MIDI
messages from a MIDI controller connected to the DIN MIDI IN.

1

Connect a power supply (not included) that provides 9V DC center­negative power and at least 50mA of current to the 9VDC power
input. When Conduit powers up, the LEDs will light up to show
that the device is powered. The color of the four ACTIVITY LEDs
will show the current TRS Jack configuration.

(See page 7 for details on output configurations.)

NOTE: For non-Strymon pedals the corresponding TRS jack may
need to be configured.

(See page 8 for details.)

Connect one of the included 1/4" TRS cables to one of the 1/4" I/O
jacks on Conduit. Connect the other end to the 1/4" MIDI control
input on your pedal. On compatible Strymon pedals, connect to
the EXP or MIDI jack set to MIDI mode.

(See your pedal’s user manual for detailed instructions.)

4

Configure the connected pedal to communicate on the desired
MIDI channel. All MIDI channels are broadcast to all outputs.

(See your pedal’s user manual for detailed instructions.)

5

If the connected pedal has the ability to send MIDI OUT, you may
want to set this to off unless bi-directional communication is
desired.

(See your pedal’s user manual for detailed instructions.)

NOTE: When Conduit is not connected to a computer via USB, all
MIDI data received at the 1/4" jacks from the pedals will be merged
and sent to the 5-pin DIN MIDI port.

Connections – Connecting Two Pedals to a Single 1/4"
TRS Jack

The Tip and Ring Send jack configuration can be used in conjunction
with a TRS splitter cable (not included) to send MIDI data to the Tip of
two 1/4" cables. This TRS jack configuration can be used to control two
pedals that receive MIDI at the Tip of a TRS connection from a single
1/4" TRS jack on Conduit.

NOTE: All 1/4" MIDI enabled Strymon pedals receive MIDI from the
Tip of a TRS connection. If you are using non-Strymon pedals, visit

strymon.net/support/conduit to confirm that the pedals used with

the Tip and Ring Send jack configuration receive MIDI at the Tip of
a 1/4" cables.

Using Conduit with a Computer

Conduit can also be used as a MIDI interface to connect devices to
your computer by using the included USB C cable.

When USB is connected, the computer will recognize 6 MIDI I/O
ports, allowing bidirectional communication with each connected
device.

• Conduit MIDI Ports 1-4 correspond with the 1/4" TRS jacks
numbered 1-4.

• Conduit MIDI Port 5 corresponds with the 5-pin DIN MIDI IN/
MIDI OUT ports.

• Conduit MIDI Port 6 will appear as a background USB
communication port.

• Conduit (PORT 1)

• Conduit (PORT 2)

• Conduit (PORT 3)
