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 benets and maximize its potential.
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 ampliers, 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 amplier.

The Suhr microMIDI can be used in many ways. Here is a short list of
possible uses and features.
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 amplier 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�

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�

MIDI Switching Device
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 amplier "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�
!!
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�
