Overview
The Suhr microMIDI Control is a MIDI controllable footswitch replacement,
making it an alternative to the mechanical footswitches that are used to con-
trol ampliers, pedals, or any device that has a footswitch input. Common
examples include amp channel switching (such as the PT15), amp reverb/
boost bypass, delay tap tempo for pedals, and more� Easily control the two
switches on the TRS jack using MIDI from your MIDI foot controller, your
DAW, or other MIDI devices�
The microMIDI Control can accept either Program Change or Control
Change commands and has the ability for momentary, latching, pulse
switching, and predetermined combinations of the two switches� The
microMIDI Control is the smallest of it's kind available today, making it easy
to add to a pedalboard or hidden behind an amplier.
Thank you for purchasing the Suhr microMIDI Control.
Please take the time to read this User Guide to get the most out of the
microMIDI Control. The more you familiarize yourself with the features of
this unit, the more you will enjoy its benets and maximize its potential.

Uses & Features
• Silent and reliable MIDI controllable footswitch replacement for Amps, pedals, and other
devices�
• Optically isolated, preventing ground loops in systems whose switch control jacks aren't
isolated from the switcher�
• Ability to switch amplier channels with computer DAW for instant silent switching during
recording�
• Adds control jack to MIDI switchers with no available control jacks�
• Compatible with Program Change (PC) and Control Change (CC) commands�
• Latching, Momentary (using CC), and pulse options of both switches�
• 4 internal switches to change MIDI Channel (1-16) available on the bottom of PCB when
the bottom lid is opened�
• MIDI IN and THRU� The THRU jack is a hardware copy of the MIDI IN jack, eliminating
latency from software THRU methods�
• Powered by standard center-negative 9V DC 2�1mm connector power supplies common
to guitar pedals�
• Less than 12mA current draw�
• The smallest solution currently available on the market�
The Suhr microMIDI can be used in many ways. Here is a short list of
possible uses and features.

9VDC Power & LED
9VDC Center negative, 2.1mm x 5.5mm
(Standard connector for pedals).
Plug in 5-pin MIDI cable from MIDI
device that will be used to send MIDI
messages to microMIDI.
MIDI THRU
This MIDI output allows MIDI to pass
through to other devices that receive
MIDI. THRU jack is a hardware copy
of the MIDI IN jack, eliminating latency
from software THRU methods.
TRS Output
Plug in TRS cable or Mono cable (See page 7)
to device that you wish to switch.
TIP LED
Blue LED indicator for
TIP switch (On when
closed, Off when open).
RING LED
Red LED indicator for
RING switch (On when
closed, Off when open).
MIDI Send/Receive LED
This green LED indicator pulses when
receiving MIDI messages.
MIDI IN

Setting MIDI Channel
This section will explain how to set the MIDI channel for the microMIDI�
All microMIDIs will be set from the factory to receive messages on MIDI
channel 1�
Steps:
1�Remove the 4 screws on back of microMIDI�
2�Review the diagram showing the key of MIDI channels and their
corresponding setting for the 4 DIP switches�
3�Arrange the 4 DIP switches�
4�Reinstall the rear cover and 4 screws�
5�After the MIDI channel is changed, the unit needs to be power cycled
to take on the new MIDI channel�
IMPORTANT NOTE: Filled-in white square represents the switch in
the ON position (UP)
!!
☺☺HELPFUL TIP: On the right side of this page you will see two
examples of DIP switch settings for communicating on MIDI channel 9
and MIDI channel 13� Example: MIDI Channel 9 Example: MIDI Channel 13 Factory Setting-MIDI Channel 1

How to connect microMIDI to an Amp (e.g. The Suhr PT15)
This guide will show the ways you can connect your microMIDI to a MIDI
foot switcher�
Steps:
1�Plug in a 9VDC Center negative, 2�1mm x 5�5mm (Standard for pedals)�
2�Connect your amplier "switch jack" via 1/4" TRS cable or mono (TS)
cable to microMIDI's TRS jack�
3�Connect a MIDI cable from the MIDI OUT of your master device to the
MIDI IN of the microMIDI Control�
4�Be sure your MIDI interface or MIDI switching device is set to
communicate on the same MIDI channel as your microMIDI (1-16)�
5�Consult the MIDI table on page 10 to learn the Program Change/Control-
ler Change numbers needed to correspond with the TRS or TS combina-
tions of your amp's footswitch�
–Optional connections– (dotted lines on diagram)
6� Connect the MIDI THRU to pass MIDI through to next device� (Optional)
IMPORTANT NOTE: Be sure to consult your MIDI interface or MIDI
switching device's manual/user-guide for the proper setup for sending
MIDI.

IMPORTANT NOTE: Mono (TS) cables can also be plugged into the
microMIDI's TRS jack, in which case only the Tip switch will be
functional� For example, this can be used for boost, tremolo, reverb
switches for amps, etc�

This section will explain how to connect your microMIDI to the TRS/FX link
of a pedal to change things such as tap tempo or modulation duration, chan-
nel selecting, and bypass�
Steps:
1�Plug in a 9VDC Center negative, 2�1mm x 5�5mm (Standard for pedals)�
2�Connect your Suhr pedal's "FX Link" via 1/8" - 1/4" TRS cable to
microMIDI's TRS jack�
3�Connect the MIDI IN to your MIDI interface or MIDI switching device with
MIDI outs�
4�Be sure your MIDI interface or MIDI switching device is set to
communicate on the same MIDI channel as your microMIDI (1-16)�
5�Consult the MIDI table on page 10 to learn the Program Change numbers
you need to correspond with the TRS combinations of your pedal�
IMPORTANT NOTE: You can also use microMIDI to switch your non-
Suhr pedal's external switch functions (Such as tap tempo or channel
select) using a TRS or mono (TS) cable�

This section will explain how to connect your microMIDI to a DAW (digital
audio workstation) using a recording interface or a USB to MIDI cable to
control an amp or the TRS/FX link of a pedal�
Steps:
1�Plug in a 9VDC Center negative, 2�1mm x 5�5mm
(Standard for pedals)�
2�Connect your amplier's "switch jack" or pedal's "FX Link" via
1/8" - 1/4" TRS cable or mono (TS) cable to microMIDI's TRS jack�
3�Connect the MIDI IN to your recording interface with MIDI outs
or to a computer using a USB to MIDI cable�
4�Be sure your DAW or MIDI switching device is set to communicate on the
same MIDI channel as your microMIDI (1-16)�
5�Consult the MIDI table on page 10 to learn the Program Change and Control
numbers you need to correspond with the TRS combinations of your amp's
footswitch or pedal's PC and CC numbers�
