Led’s - In “Preset” or
“Tap” mode these
LEDs will indicate
what preset you are
on if you are in the
rst 4 presets. In
“Tap” mode Led 1
will blink to the
tempo you have
tapped in. The leds
will ash in various
ways to indicate
changing of modes
or settings.
Preset/Tap - When in
“preset” mode, pressing
will increment you
through the rst 4 presets
and wrap back to preset 1.
In “Tap”mode pressing
will be read as a tap input
and will sync the delay
time to your tap input.
Double press and hold
will switch you between
these two modes. Holding
this switch will enter you
into “Save”mode. Another
press will save the current
parameter positions to
the currently selected
preseet. While in “Save”
mode send a midi
message to save those
settings to the desired
midi preset
Bypass Switch-
Press to activate/deactivate the pedal.
Hold to start the ramp feature, release
to ramp back to the parameters
starting state.

DOSE - Takes you from
100% dry (all the way left)
to 100% wet (all the way
right.
MODE - Choose between 8
algorithms organized into 4
categories.
PULSE - Adjusts the time
of your delay
REGEN - Adjust the
feedback of your delay
M - The “Mutation” knob
changes its function
based on what algorithm
you are on.
DIV - Choose between 5
tap divisions. 1/2, .1/4,
1/4, .1/8, 1/8
1 2 3 4

Midi In/Out - These take a trs 3.5mm cable to send/receive midi messages.
The Surgeons default is set to MIDI channel 1.
USB - Takes a USB C connection to send/receive midi and connect to the
computer editor. Use the computer editor to create/edit presets, edit global
settings and update the firmware.
Exp - Connect any standard TRS expression pedal for expression control. Not
only can you can assign any parameter to be controlled via expression but
you can also set their heel and toe position.
EQ - In the “EQ” mode we give you two algorithm options. You can choose between a low
pass or high pass lter in the feedback loop. The“Mutation” knob lets you adjust the freq.
MOD - In the “Mod” mode you can choose between two algorithms where one lets you
control the depth and one the rate of the modulation.
AF - The“Auto FIlter” mode lets you choose between two algorithms where one lets you
control the depth and one the rate of the lter.
DUAL - The “Dual” delay mode gives you a 2nd delay time. In the “UnSynced” algorithm
the time is adjsutable to whatever you want it to be. In the “Synced” algorithm you can set
a tap division for the 2nd delay time to be synced to your main delay time.

Global Settings:
To adjust the global settings on your surgeon without the editor simply power on your
pedal while holding the “bypass”switch.
While holding the bypass switch adjust the following knobs for the desired change.
Dose - This will adjust the boot state of your pedal.
1: O
2: On
3: Preserve State on power cycle
Regen - This will adjust the Tails mode for the surgeon. If “o” then your delays will be cut
o when the pedal is bypassed. If “On” then your delays will continue when the pedal is
turned o although no delays will be created.
1: O
2: On
Pulse - Adjust whether the Surgeon ignores or listens to external MIDI clock.
1: Ignore
2: Listen
Mode- Adjust the MIDI out.
1: Thru
2: Out
3: Merge
M - Sets the MIDI channel for your pedal. The surgeon comes defaulted to channel 1. The
leds will use binary to show what channel you are set to.
