BOOST
Adjusts the amount of boost
when the boost circuit is
active. Typical boost ~14dB in
Flat Clean boost.
COMPRESSION
Turning clockwise
increases compression by
lowering the threshold.
Fully counterclockwise, no
compression is applied.

BOOST
Engages and disengages the
variable boost independent
of the COMP. The boost is
post-compression. RED LED
ON indicates that the boost is
engaged.
NOTE: When both BOOST and COMP are disengaged,
the bypass is either Buffered Bypass or True Bypass
depending on the selected mode.

MIDI Functionality - Configuring to Use MIDI
Using MIDI unlocks a set of tools that can be used to load any of
Compadre’s 300 preset locations using a suitable MIDI controller or
interface connected to Compadre’s FAV/MIDI jack. This requires a MIDI
controller/interface with at least one quarter-inch output or a Strymon
MIDI EXP cable. When using a Strymon MIDI EXP Cable, the MIDI OUT
mode must be set to OFF.
Check strymon.net/support/compadre for a list of compatible devices.

Step 1 – Set FAV/MIDI Jack Mode to MIDI Mode
Press and hold the
1
COMP footswitch while
connecting power to
the pedal. Once both
LEDs flash, release the
footswitch.
2
Turn the BOOST knob
clockwise until the BOOST
LED is BLUE.
3
Press the BOOST or
COMP footswitch again
to store the FAV/MIDI
jack mode.
NOTE: If you are only sending data to Compadre using the Strymon
MIDI EXP Cable, the MIDI Output mode must be set to OFF.
(See page 16 for details on configuring the MIDI Output Mode.)
pg 14
COMPADRE - Dual Voice Compressor & Boost
MIDI Functionality - Configuring to Use MIDI (cont.)
Step 2 – Set MIDI Channel: This determines which MIDI channel
Compadre will use to send and receive MIDI data. To select channel
4-16, you will need to connect Compadre to a MIDI device.
Press and hold the
1
BOOST footswitch while
connecting power to
the pedal. Once both
LEDs flash, release the
footswitch.
2
Turn the BOOST knob to set the MIDI communication channel.
BOOST LED indicates status.
Channel 1: GREEN (default)
Channel 2: AMBER
Channel 3: RED
Channel 4 -16: BLUE (Requires 1⁄4” MIDI connection.)
Once the LED turns BLUE , it will blink until the pedal receives a
MIDI Program Change message. Once a message is received, the
pedal will be set to the MIDI channel that carried the message
and the LED will stop blinking.
3
Press the COMP or BOOST footswitch again to store the MIDI channel
and begin using Compadre.
pg 15
COMPADRE - Dual Voice Compressor & Boost
MIDI Functionality - Configuring to Use MIDI (cont.)
Step 3 – Set MIDI Output Mode
Determines whether Compadre will send MIDI data out.
Press and hold the
1
BOOST footswitch while
connecting power to
the pedal. Once both
LEDs flash, release the
footswitch.
TIP: A simple way to check that
communication is working is
to send CC #27 with a value of
127 when the COMP footswitch
is OFF. This will turn the COMP
footswitch on if MIDI is properly
connected and configured.
2
Turn the COMPRESSION knob to select the MIDI OUT mode. The
COMP LED will flash momentarily to indicate status.
On: GREEN Using Compadre’s knobs and switches generates
MIDI messages that are sent out of Compadre. (Set to ON when
using MultiSwitch Plus.)
Through: AMBER Incoming MIDI messages are sent out of
Compadre without any additional MIDI messages generated by
Compadre.
Off: RED (default) No MIDI messages are sent out of Compadre.
3
Press the BOOST or COMP footswitch again to set the MIDI output
channel and begin using Compadre.
pg 16
COMPADRE - Dual Voice Compressor & Boost
MIDI Functionality - Saving Presets
When in MIDI mode, the current state of the pedal can be saved to
any of Compadre’s 300 preset locations at any time.
To enter SAVE mode,
1
press and hold the
BOOST footswitch. The
BOOST LED will blink
BLUE to indicate that it
is waiting to receive a
MIDI Program Change
message.
2
Send the unit a MIDI Program Change message from the
connected MIDI device. The BOOST LED will flash and Compadre
will save the current state of the pedal to that preset location.
OR
Press the BOOST footswitch to save the current state of the
pedal to the currently loaded preset location.
OR
Press the COMP footswitch to cancel the save operation.
pg 17
COMPADRE - Dual Voice Compressor & Boost
MIDI Functionality - MIDI Specifications
MIDI PROGRAM CHANGES
Compadre contains 300 preset locations, numbered sequentially from
0-299. Because MIDI Program Change messages have a maximum
number of 128 (0-127) the presets are grouped into three MIDI patch
banks.
MIDI BANK 0 = PRESETS 0-127
MIDI BANK 1 = PRESETS 128-255
MIDI BANK 2 = PRESETS 256-299
Compadre always powers up in MIDI Patch Bank 0, so if you plan to
stay within the first 127 presets, simply send a standard MIDI Program
Change message to load a preset.
If you will be using MIDI Banks 1 and/or 2, it is advisable to send a
standard MIDI Bank Change message (MIDI CC# 0 with a value equal
to the MIDI Bank#) before each MIDI Program Change.
Selecting bank 0, patch 127 will put Compadre into Manual mode.
In this mode, the pedal will be set to the current knob and switch
settings. No preset data can be stored at this preset location.

NOTES:
The audio processing in Compadre is completely analog, but it is
digitally controlled. This allows you to save and recall up to 300 presets
and have full MIDI control over the analog parameters.
When COMP is bypassed, the compressor is completely removed from
the signal path.
The LEVEL knob is only active when the compressor is engaged,
and it is located after the boost in the signal chain. This gives you
the flexibility to allow the DIRTY boost setting to provide significant
overdrive without requiring a jump in volume.
