About the Workshop Booklets
Some Notes About the GT-10’s Display
The GT-10 Guitar Effects Processor is BOSS’ most powerful floor-based
effects unit to date, packing over 30 years of industry-leading tone knowhow under one hood. Onboard is a history of BOSS effects, COSM® vintage
amps and stomps, studio-quality A/D-D/A conversion, and much more.
There’s even a real BOSS looper built in, with up to 38 seconds of sound-onsound recording. The GT-10 is truly the ultimate portable tone machine for
guitarists, from stage to studio and beyond.
Each GT-10 Workshop Series booklet focuses on one GT-10 topic, and is
intended as a companion to the GT-10 Owner’s Manual.
About This Booklet
The GT-10 offers many different ways to control its extensive arsenal of
effects in real time as you’re performing. We’ll tell you all about them in this
booklet.
Understanding the Symbols in This Booklet
Throughout this booklet, you’ll come across information that deserves
special attention—that’s the reason it’s labeled with one of the following
symbols.
A note is something that adds information about the topic at hand.
The Play Screen
The Play screen is the GT-10’s “home” screen. It’s the screen that’s displayed
after the GT-10 finishes its power-up sequence.
You’ll usually want to return to the Play screen when you’re
done editing any GT-10 functions. This is accomplished by
pressing EXIT one or more times.
Throughout this Workshop booklet, we’ll usually start procedures from the
Play screen.
Setting the Display Mode
The GT-10 offers a number of different display modes, allowing
you to choose how various information is shown. To scroll
through the available display modes, press the DISPLAY MODE
button.
When you’re on the Play screen, each press
of the DISPLAY MODE button scrolls through
eight different Play screen variations. For the
purposes of this booklet, we’ll be using Play
Screen 1 (shown to the right), which is the
GT-10’s factory default.
A tip offers suggestions for using the feature being discussed.
Warnings contain important information that can help you avoid
possible damage to your equipment, your data, or yourself.
When you’re on an editing screen for an
effect or a control assignment, pressing
DISPLAY MODE toggles between an iconbased screen and a list-based screen. For the
purposes of this booklet, we’ll be using the
list-based screen, as shown to the right.
Once you’re familiar with operating the GT-10, feel free to use
whatever display modes you wish.

Realtime Effects Control Overview
Types of Realtime Controllers
The GT-10 has a staggering number
of onboard effects, including COSM
preamps, distortions and overdrives,
delays, reverbs, modulation effects like
chorus, flanger, and phaser, and tons
more. Every effect has parameters for
adjusting its sound and turning the
effect on and off.
Realtime effects control allows you to adjust one or more of an effect’s
parameters as you play. This is accomplished using the foot switches and
pedal on the GT-10 itself, or with an external pedal, external foot switches,
or MIDI devices connected to the GT-10. Any device that’s used for realtime
effects control is called, suitably, a “realtime controller.”
You’re probably already very familiar with using one of the GT-10’s realtime
controllers: the onboard expression pedal. In most preset patches, the
expression pedal is assigned to a function called “foot volume,” and this
allows you to control a patch’s volume with the pedal. You may have also
noticed that, in many cases, you can step on the pedal’s toe switch and turn
the expression pedal into a wah or pitch bend pedal.
Foot volume is the GT-10’s version of a “stompbox” volume pedal, and
its position in the effects chain can be adjusted, just as you’d use a
hardware volume pedal in conjunction with a bunch of stompboxes.
This is in contrast to an overall volume control, which controls the
patch volume after all the effects. You can have the expression pedal
control foot volume, the overall volume, or many other things, as
you’ll discover reading through this booklet.
These are all great examples of your ability to control GT-10 effects in real
time. However, they only scratch the surface of the amazing things you can
do, because nearly any effect parameter in the GT-10 can be controlled as
you play. Using some creative thinking, you can use this power to create a
massive arsenal of flexible and innovative guitar sounds that are custommade for your music.
The GT-10 offers many different realtime control options, both built in and
external.
Onboard the GT-10
Foot Switches
The GT-10 provides three different onboard foot switches for controlling
effects. These are used to turn effects on/off, toggle between two different
parameter values, and more. All provide LED status indicators.
• These foot switches are
CTL 1 and CTL 2—
located on the front panel, to the right of the
number foot switches used to select patches.
• Also called the “expression pedal switch,” this
EXP PEDAL SW ON/OFF—
foot switch is located under the toe of the onboard expression pedal. To
operate the switch, press down firmly on the pedal’s toe.
Status LED
Press the toe of the pedal to
operate the expression
pedal switch
The foot switches can be used either in a “toggle” mode—where the switch
holds the assigned parameter value after it’s pressed—or in a “momentary”
mode, where the assigned parameter’s value changes only while the switch
is held down.
When assigning parameters to the expression pedal switch, it’s referred
to as “EXP PEDAL SW” or “EXPSw” in the GT-10’s display.
3
Expression Pedal
In most cases, you’ll use the onboard expression pedal to
control the GT-10’s PEDAL FX group. Effects in this group
include foot volume, pedal bend, and wah.
The pedal can also be used to continuously vary other effect
parameters, such as the timing or level of a delay effect, the
speed of a modulation effect, or the amount of overdrive—
nearly anything you can imagine.
As with the foot switches, you can also use the pedal to turn effects on/off,
toggle between parameter values, and more.
The wave pedal continuously varies—or “modulates”—a parameter between
two assigned values. The speed of the value change can be set manually or
synced to the GT-10’s master tempo.
The wave pedal continuously adjusts a parameter between two assigned values.
Input Level
When assigning parameters to the onboard expression pedal, it’s
referred to as “EXP1” in the GT-10’s display.
The Internal Pedal and Wave Pedal
These pedals are “virtual” pedals that live inside the GT-10. They control
parameters assigned to them automatically.
The internal pedal functions like an automatic expression pedal, moving a
parameter from one value to another over a predetermined period of time.
To initiate an internal pedal assignment, you trigger it manually with another
realtime controller, like a foot switch. Alternately, you can trigger the internal
pedal at the moment a patch is selected.
Triggering the internal pedal with a foot switch like CTL 1 (or another controller)
adjusts an assigned parameter from one value to another over a predetermined time.
For the ultimate in expression, the GT-10 allows you to control parameters
simply with the dynamics of your playing. When you play soft, hard, and
anything in-between, the GT-10 senses these dynamic changes as changes
in input level. Thus, by assigning a parameter to be controlled via input level,
you can adjust it with how hard or soft you play.
With the input level assignment, you can continuously adjust
a parameter with your playing dynamics.
External Control
EXP PEDAL 2/CTL 3,4
On the GT-10’s rear panel, there’s a jack labeled EXP PEDAL 2/CTL
3,4. Here, you can connect either an optional expression pedal
or up to two optional foot switches. When connected, these
devices can be used to supplement the onboard expression
pedal and foot switches.
4
Expression pedals that will work here include the BOSS FV-500H/-500L and
the Roland EV-5.
MIDI
GT-10 effect parameters can also be controlled via MIDI
using Control Change—or “CC”—messages sent from
an external device. To control the GT-10 in this way,
connect the MIDI OUT jack of the sending device to the
GT-10’s MIDI IN jack.
BOSS FV-500L Roland EV-5
When assigning parameters to an external expression pedal, it’s
referred to as “EXP2” in the GT-10’s display.
BOSS foot switches that can be used include the FS-6, a two-button foot
switch, or the FS-5U, a single-button foot switch.
BOSS FS-6 BOSS FS-5U
You can connect two FS-5Us to the EXP PEDAL/CTL 3,4 jack with a
special “Y” cable (such as the Roland PCS-31).
When assigning parameters to a connected FS-6 or two connected
FS-5Us, the two switches are referred to as “CTL3” and “CTL4” in
the GT-10’s display. If a single FS-5U is connected, use the “CTL3”
assignment.
To learn more about connecting an external expression pedal or
external foot switches to the GT-10, refer to the GT-10 Owner’s
Manual.
To learn more about using MIDI devices with the GT-10, refer to the
GT-10 Owner’s Manual.
Cool Things You Can Do with Realtime Effects Control
To get your brain around some of the creative possibilities
for using the GT-10’s realtime control options, here are
just a few things that you can do:
• By assigning one
Turn effects on/off within a patch—
or more foot switches to the on/off parameter of
one or more effects, you can turn them on and of without switching
patches.
• Assign the Preamp A/B
Switch between two different COSM preamps—
function to a foot switch to toggle between two different COSM amps
within a single patch.
• Assign SOLO to a foot switch for a volume
Kick on the SOLO boost—
boost during solos.
• Assign a foot switch to the Tap function, and then
Tap in the tempo—
tap in a song’s tempo as you play to synchronize the GT-10’s time-based
effects to your song.
• By assigning a foot switch to the GT-10’s
Switch channels on your amp—
AMP CTL function and connecting the AMP CONTROL jack to the foot
switch jack on your channel-switching guitar amp, you can toggle
between its channels from the GT-10. (Refer to your amp’s owner’s
manual to learn more about its channel-switching functions.)
• The GT-10’s BANK
Extend your control of the GT-10’s built-in looper—
pedals control the basic operation of the Phrase Loop function. Using
realtime control assignments, you can gain additional control over the
looper.
5
Control unconventional effects parameters with the expression pedal—• The
standard use of the expression pedal is to control guitar effects such as
volume, wah, and even whammy-style pitch bend. But you can also
control a ton of other neat things with the pedal, such as delay level or
time, the gain of a COSM preamp or a distortion effect, or the rate of the
flanger effect—even all of them at once. Nearly anything is possible!
• Using the
Create sophisticated effect sounds with a sense of motion—
internal and wave pedals, you can create all sorts of “automatic” effects
that would be difficult or impossible to accomplish manually. For
example, you can assign the internal pedal to gradually increase or
decrease the rate of a tremolo or slicer effect with one press of a foot
switch. Or, you can use the wave pedal to continuously vary the filter of
the auto wah or an EQ frequency to create realtime filter effects.
These suggestions only scratch the surface of the things you can do with
realtime effects control. The only limit is your imagination!
GT-10 Preset Patches That Use Realtime Controllers
Before we show you how to make your own realtime control assignments,
let’s examine some of the GT-10’s preset patches that make use of realtime
controllers. This will give you a good hands-on overview of what’s possible
with realtime effects control.
When the GT-10 ships from the factory, all of its realtime controllers
are assigned to follow settings made in each individual patch. However,
you have the ability to override the patch settings for individual
controllers with system-wide settings, so that they react the same no
matter what patch is selected. If you’ve set your GT-10 in this way,
some of the following examples may not behave as described. We’ll
show you how to set patch and system-wide preferences in “Setting
Realtime Controllers to the Same Function for All Patches” near the
end of this booklet.
P01-3: AMERICAN LEGEND
This patch combines a classic American
tweed amp with some stompbox-type
effects. It also includes two effects—tremolo
and spring reverb—that were built into
vintage American “Blackface” amps.
Effects used in this patch:
• PREAMP (Channels A and B)•
OD/DS
FX-1 (PARA EQ)• FX-2 (TREMOLO)•
REVERB (Spring)• PEDAL FX (FOOT VOLUME/WAH)•
When the patch is first called up, PREAMP A, FX-1, and PEDAL FX (FOOT
VOLUME) are on. Use the onboard realtime controllers as follows:
• When this foot switch is pressed, two things happen at once: the
CTL 1—
OD/DS effect toggles on/off, and PREAMP toggles between Channel A
and Channel B.
• When this foot switch is pressed, both FX-2 and REVERB are
CTL 2—
toggled on/off.
As you can see in the two examples above, a foot switch can be
assigned to control more than one parameter with a single action. In
fact, the GT-10 allows you to adjust up nine different parameters at
once with a single realtime control action!
EXP PEDAL SW ON/OFF—• Pressing this switch toggles the expression
pedal function between controlling FOOT VOLUME and WAH.
• Controls FOOT VOLUME or WAH, depending on the
Expression pedal—
EXP PEDAL SW ON/OFF setting.
To select patches from the GT-10’s front panel, turn the dial while the
Play screen is displayed.

P02-3: IRISH DELAY
This patch combines two vintage British
combo amps with a timed delay effect,
creating a sound first popularized by UK
bands in the ‘80s.
Effects used in this patch:
• CHORUS•
PREAMP (Channels A and B)
DELAY• REVERB•
PEDAL FX (FOOT VOLUME/WAH)•
When this patch is selected, PREAMP A and B (both channels), CHORUS,
REVERB, and PEDAL FX (FOOT VOLUME) are on. Use the onboard realtime
controllers as follows:
• This switch is assigned to BPM Tap, allowing you to set the speed
CTL 1—
of the GT-10’s master BPM (beats per minute) rate by “tapping” in time
on the foot switch. The delay effect is assigned to follow the master BPM
with a dotted eighth-note delay time, creating a cool rhythmic effect.
When CTL 1 or CTL 2 are set to control BPM Tap, the switch’s LED
flashes in time with the master BPM rate.
CTL 2—• When this foot switch is pressed, DELAY is toggled on and off.
• When this switch is pressed, the expression
EXP PEDAL SW ON/OFF—
pedal function toggles between controlling FOOT VOLUME and WAH.
• Controls FOOT VOLUME or WAH, depending on the
Expression pedal—
EXP PEDAL SW ON/OFF setting.
When this patch is called up, PREAMP A, EQ, FX-1, FX-2, and PEDAL FX (FOOT
VOLUME) are on. Use the realtime controllers as follows:
• When this foot switch is pressed, PREAMP toggles between
CTL 1—
Channel A to Channel B.
• When this foot switch is pressed, the speed of the ROTARY effect
CTL 2—
toggles between FAST and SLOW.
The GT-10’s ROTARY effect emulates the sound of a vintage “rotating
speaker” cabinet. When the speed control is toggled, the speed change
is gradual, just as it is when adjusting the motor speed on an actual
rotating speaker cabinet.
EXP PEDAL SW ON/OFF—• When this switch is pressed, the expression
pedal function toggles between controlling FOOT VOLUME and PEDAL
BEND.
• Controls FOOT VOLUME or PEDAL BEND, depending
Expression pedal—
on the EXP PEDAL SW ON/OFF setting.
P12-4: LEAD+CTL FLANGE
This patch combines a classic British stacktype amp with modulation, delay, and
reverb effects.
Effects used in this patch:
• DELAY•
PREAMP (Channels A)
FX-1 (PHASER)• FX-2 (FLANGER)•
REVERB (Room)• PEDAL FX (FOOT VOLUME/WAH)•
P03-4: ROTARY CONTROL
Here, we have a classic British stack-type
amp combined with a rotary speaker effect.
Effects used in this patch:
• EQ•
PREAMP (Channels A and B)
FX-1 (TONE MODIFY)• FX-2 (ROTARY)•
PEDAL FX (FOOT VOLUME/PEDAL BEND)•
When the patch is selected, PREAMP B, DELAY, REVERB, and PEDAL FX (FOOT
VOLUME) are on. Use the realtime controllers as follows:
• When this foot switch is pressed, FX-1 toggles on/off.
CTL 1—
• Here, this foot switch is set to the “momentary” setting. When
CTL 2—
CTL 2 is pressed, FX-2 turns on. When the switch is released, FX-2 turns
off again.
7
Using foot switches with the momentary setting is great for adding
brief, expressive effects as you play.
EXP PEDAL SW ON/OFF—• When this switch is pressed, the expression
pedal function toggles between controlling FOOT VOLUME and WAH.
• Controls FOOT VOLUME or WAH, depending on the
Expression pedal—
EXP PEDAL SW ON/OFF setting.
P32-3: PEDAL UNI-V
This patch blends two different vintage
American amps with chorus, delay, and
reverb effects. Featured is the UNI-V effect,
with its rate controlled by the expression
pedal.
Effects used in this patch:
• DELAY•
PREAMP (Channels A and B)
FX-1 (UNI-V)• CHORUS•
REVERB (Plate)•
When the patch is selected, all the above effects are on. Use the realtime
controllers as follows:
• Just like in P02-3: Irish Delay, this foot switch is assigned to BPM
CTL 1—
Tap, so you can set the speed of the GT-10’s master BPM by tapping in
time on the foot switch. In this patch, however, the delay effect is set to
follow the master BPM with a quarter-note delay time.
• When this foot switch is pressed, DELAY is toggled on and off.
CTL 2—
• When this switch is pressed, the expression
EXP PEDAL SW ON/OFF—
pedal function toggles between controlling UNI-V rate or nothing.
• Controls the UNI-V rate or nothing, depending on the
Expression pedal—
EXP PEDAL SW ON/OFF setting.
P47-4: A=CL+MOD | B=OD
In this patch, pressing CTL 1 switches
between two radically different sounds.
When listening to the GT-10 in stereo, you’ll
hear each sound toggle between the left
and right outputs.
Effects used in this patch:
• EQ•
PREAMP (Channels A and B)
FX-1 (T.WAH)• FX-2 (ROTARY)•
DELAY• REVERB (Spring)•
PEDAL FX (FOOT VOLUME/WAH)•
CTL 1—• When this foot switch is pressed, PREAMP toggles between two
different PREAMP settings. In one setting, Channel A’s volume is turned
down, while Channel B’s volume is turned up. In the other setting, the
opposite occurs: Channel A’s volume is turned up, while Channel B’s
volume is turned down.
• When this foot switch is pressed, DELAY is toggled on/off.
CTL 2—
• Pressing this switch toggles the expression
EXP PEDAL SW ON/OFF—
pedal function between controlling FOOT VOLUME and WAH.
• Controls FOOT VOLUME or WAH, depending on the
Expression pedal—
EXP PEDAL SW ON/OFF setting.
P49-1: MANY EFFECTS CLN
As its name suggests, this is a clean patch
that combines many effects together. We’ve
included it here to show you the internal
pedal in action.
Effects used in this patch:
• PREAMP (Channels A and B)•
COMP
FX-1 (AUTO WAH)• FX-2 (PHASER)•
DELAY• CHORUS•
REVERB (Modulate)• PEDAL FX (FOOT VOL/PEDAL •
BEND)
8
When the patch is selected, all the above effects are on. Use the realtime
controllers as follows:
• When pressed, CTL 1 activates the internal pedal, which is
CTL 1—
assigned to control the time of the DELAY effect. The switch is set for
momentary action, so you only have to press it briefly to initiate the
internal pedal’s assigned parameter adjustment.
To see what the internal pedal is doing, press the DELAY button on
the GT-10’s front panel, and watch what happens to the DLY TIME
parameter in the display each time you press CTL 1.
The current state of any realtime control assignments are saved when
you save a patch. For example, let’s say that you’ve assigned CTL 1 to
turn DELAY on/off. If DELAY is on when the patch is saved, it will be
on the next time the patch is recalled. Even if you use CTL 1 to turn
DELAY off and then switch to another patch without saving, DELAY is
still automatically turned on again the next time the patch is recalled,
since it was originally saved in that state.
Patch Settings Versus System Settings
CTL 2—• This switch triggers a second internal pedal assignment that
adjusts the PEDAL BEND effect.
• Pressing this switch toggles the expression
EXP PEDAL SW ON/OFF—
pedal function between controlling FOOT VOLUME and PEDAL BEND.
(When the patch is selected, PEDAL BEND is on.)
• Controls FOOT VOLUME or PEDAL BEND, depending
Expression pedal—
on the EXP PEDAL SW ON/OFF setting. (Moving the pedal with PEDAL
BEND on manually controls the same parameter as that assigned to
CTL 2. When CTL 2 is pressed, the internal pedal automatically cycles
PEDAL BEND through its assigned range.)
Assigning Realtime Controllers
This section discusses assigning realtime controllers in patches. After
you make an assignment, you’ll need to save the patch to a user patch
location by using the WRITE procedure, otherwise your changes will be
lost when you select another patch or turn off the GT-10. If you don’t
know how to save user patches, see Chapter 3, “Saving a Tone” in the
GT-10 Owner’s Manual.
Saving a patch overwrites the data in the selected destination patch.
If the destination patch contains data you want to keep, select a
different patch, or back up its data to a computer via USB before
proceeding. To learn more, see the GT-10 Owner’s Manual.
Before we talk about making your
own custom control assignments,
let’s discuss the difference between
patch and system assignments.
Every patch has its own unique set of realtime control assignments. This
gives you the ability to complete reconfigure all realtime controllers with a
single patch change.
If you like, you have the option of setting realtime controllers to follow
system-wide settings instead of patch settings. When you do this, the
realtime control assignment remains the same no matter what patch is
selected.
The following realtime controllers can be independently configured to
follow either patch or system-wide settings:
• EXP PEDAL SW•
EXP 1
EXP 2• CTL 1•
CTL 2• CTL 3•
CTL 4•
When the GT-10’s at its factory default settings, all the above
controllers are set to follow the settings made in each patch.
9
Choosing a system-wide setting is great when you know you want to use
an assignment the same way in every patch. For example, you may want to
set PEDAL FX to FOOT VOLUME or use CTL 2 for tap tempo in every patch.
Setting a controller to system-wide status saves you from having to make the
same settings over and over in all your patches.
System-wide settings are also a great way to temporarily override
patch control settings for a special application. Setting a particular
realtime controller for system-wide use doesn’t alter the settings
stored for that controller in each patch; it only ignores them.
We’ll show you how to set a realtime controller to system-wide status a little
later. For now, we’ll just focus on making realtime controller assignments in
patches.
Quickly Assigning Common Functions to Realtime
Controllers
On the SW&PDL FUNCTION screen, you
can quickly assign commonly used effects
parameters and other functions to the
onboard pedal and switches. These include
things like assigning a foot switch to turn a
particular effect group on/off, setting a foot
switch for tap tempo, or setting the function of PEDAL FX.
For most basic effects adjustments, these “shortcut” assignments will be
all you’ll ever need to set. Following are tables that show the available
assignments.
SW&PDL FUNCTION Assignments: CTL 1, CTL 2, and
EXP Sw
Function What it Does
Off No assignment.
Ch. A/B Switches between Preamp CHANNEL A and B.

Num Inc Switches the next-highest patch number.
Num Dec Switches the next-lowest patch number.
Bank Inc Switches the next-highest patch bank.
Bank Dec Switches the next-lowest patch bank.
LED Moment The switch’s LED is turned on when the switch
is pressed, and turned off when the switch is
released. (Available for CTL 1 and CTL 2 only.)
LED Toggle The switch’s LED is turned on when the switch is
pressed, and stays on until the switch is pressed
again. (Available for CTL 1 and CTL 2 only.)
The “LED Moment” and “LED Toggle” assignments don’t control any
effects; they only control how the status LEDs on CTL 1 and CTL
2 behave. This can be useful when making more detailed control
assignments on the ASSIGN 1-8 screens, as described in a bit.
SW&PDL FUNCTION Assignments: EXP 1
Function What it Does
Off No assignment.
Foot Volume Assigns EXP 1 to PEDAL FX: Foot Volume.
Pedal Bend Assigns EXP 1 to PEDAL FX: Pedal Bend.
WAH Assigns EXP 1 to PEDAL FX: WAH.
PB/FV Assigns EXP 1 to toggle between PEDAL FX: Pitch
Bend and PEDAL FX: Foot Volume.
WAH/FV Assigns EXP 1 to toggle between PEDAL FX: WAH
and PEDAL FX: Foot Volume.
If you’re setting EXP1 to the dual-function assignments PB/WAH or
WAH/FV, make sure you set one of the switches to “Pedal FX” so you
can toggle between the two settings. (Setting EXP PEDAL SW for this
purpose usually makes the most sense.)
Making Assignments on the SW&PDL FUNCTION Screen
From the Play screen, press MASTER/PEDAL FX.1
Turn the dial to select PDL FX, and then press ENTER.2
If necessary, use the 3 3 and 4 buttons to navigate to the SW&PDL
FUNCTION screen (Page 1 in the display). If the screen is not displayed
in list view as shown below, press DISPLAY MODE so it is.
Use the PARAMETER 1-4 knobs under the display to set the desired 4
function for CTL1, CTL2, EXPSw, and EXP1. (If you don’t want to assign
a function to a particular foot switch or pedal, select “Off.”)
If you see a warning message that says
“XXX PREFERENCE is SYSTEM!” when
performing Step 4 above, it means that
the particular controller you’re trying to
adjust is currently set to system-wide
operation. To set the preference back
to Patch, press EXIT, and then follow the
procedure described in “Setting Realtime
Controllers to the Same Settings for All
Patches” on Page 17 in this booklet.
When you’re done, press EXIT twice to return to the Play screen. To 5
save the settings you’ve just made, don’t forget to save your patch to
a user patch location.

Using the ASSIGN Screens to Make Detailed Realtime
Control Assignments
On the ASSIGN screens, you can have some
real fun creating sophisticated realtime
control assignments. This is where you
make settings for all the GT-10’s realtime
controllers: the onboard foot switches and
pedal, the wave and internal pedals, input
level, external foot switches, an external
pedal, and MIDI.
There are eight different ASSIGN screens (ASSIGN 1-8), allowing you to make
eight different realtime control assignments. Additionally, you can specify
how the realtime controllers behave. Here are just a few examples of things
you can do on the ASSIGN screens:
•
Assign a single foot switch to turn multiple different effects on/off with a
single press
•
Assign a foot switch to toggle between two different parameter values in a
single effect (or many effects)
•
Assign an effect (or multiple effects) to turn on/off only when a foot switch
is pressed and held
•
Continuously control any effects parameter (or multiple parameters) with
the onboard expression pedal or an expression pedal
•
Assign a foot switch to the internal pedal and vary an effects parameter
over time when the foot switch is pressed
•
Have an effects parameter vary continuously with the wave pedal
Assign a parameter to be adjusted by varying your picking dynamics •
Assign parameters to respond to incoming MIDI CC messages•
Using the ASSIGN screens, you can control your GT-10 effects to an
unprecedented degree, giving you an amazing amount of expressive control
over your guitar tone.
Any realtime control assignments you make on the ASSIGN screens are
in addition to the controls assignments made in the previous section,
“Quickly Assigning Common Functions to Realtime Controllers.”

About the Target and Source
When working with control assignments, the “target” is what you want to
control, while the “source” is the mechanism with which you control the
target.
TargetSource
Secondary target
Primary target
Primary and secondary target locations on an ASSIGN screen. Scroll down to set the source controller.
We’re using the terms “primary target” and “secondary target” only
for the purposes of this booklet, to help you categorize the many
control assignments that are available. In the GT-10’s display and the
GT-10 Owner’s Manual, both are simply referred to as “Target.”
On the ASSIGN screens, the source is the realtime controller—CTL1, CTL2,
EXP1, etc.—that you wish to use to control the chosen target parameter.
Source
Source location on an ASSIGN screen.
On each of the eight ASSIGN screens, there is a single target/source
relationship. If you want to use a specific source to control multiple
targets at once—or if you want to control a specific target with
multiple sources—simply set up those relationships one by one using
multiple ASSIGN screens.
When working in the ASSIGN screens, the primary target is the effect or
function you wish to control, while the secondary target is the particular
parameter within that effect or function.
For example, let’s say that you’d like to control a parameter in the chorus
effect. For the primary target, you’d choose “CHORUS.” For the secondary
target, you’d choose the desired chorus parameter, such as On/Off, Rate,
Depth, etc.
Available Targets
On the ASSIGN 1-8 screens, you can target nearly any GT-10 effects
parameter or function for realtime control. For a detailed listing of every
available parameter and function, see the TARGET PARAMETER tables in the
“Parameters Guide” chapter in the GT-10 Owner’s Manual.
Another way to see them is on the GT-10 itself: just scroll through the Target
parameters on an ASSIGN screen to see every available parameter and
function, as described in Step 5 of “Making Settings in the ASSIGN Screens”
(coming up on Page 15).

About Minimum and Maximum Values
Parameter Adjustment with Continuous Controllers
On the ASSIGN screens, the “Min” (minimum) and “Max” (maximum) values
represent the range over which you can adjust the target parameter with the
source. How these values behave depends on whether you’re using a foot
switch or a “continuous controller” (like an expression pedal) as the source
for controlling the target.
Parameter Adjustment with Foot Switches
When a foot switch is assigned as the control source, it toggles between the
minimum and maximum values you’ve set. For two-way parameters, such as
“on” and “off,” this is a no-brainer. Just set the minimum value to Off and the
max value to On (or vice versa), and you’re good to go.
However, when a parameter is a numeric value (as is the case most of the
time), the foot switch will toggle between the numeric values that you’ve
set. For example, if you’ve targeted the drive parameter in a distortion effect
and you’ve selected a foot switch as the source, you can use it to toggle
between the two different drive values. Or, if you’ve targeted the rate in the
flanger effect, you can toggle between the two different rate values.
Each press of a foot switch that’s assigned as the source toggles between
the minimum and maximum values assigned to the target.
A “continuous controller” is a realtime controller that continuously varies a
parameter through the entire range between the minimum and maximum
target values. On the GT-10, any realtime controller that’s not a foot switch—
expression pedals, MIDI CC messages, the internal and wave pedals, and
input level—is considered a continuous controller.
Let’s say that you’ve targeted the delay level in a delay effect, and you’ve
selected the onboard expression pedal (EXP1) as the source. When you
operate the pedal, it will continuously vary the delay level between the
minimum and maximum values you’ve set. Or, if you’ve selected the wave
pedal as the source instead, the delay level will automatically vary between
the minimum and max values, with the speed of the value adjustment
determined by the rate that you’ve set.
Operating an expression pedal (or other continuous controller) that’s assigned as the source
continuously varies the target parameter between the minimum and maximum values.
Continuous controllers aren’t just for numeric parameter values; you
can also use them as the source when you wish to control two-way
parameters like on and off. In such cases, the parameter value will
toggle at the controller’s midpoint.
Most of the time, you’ll probably want a foot switch to hold a
parameter after it’s pressed. To set this behavior, select “Toggle” on
the Src Mode line in an ASSIGN screen. If you want to execute the
assigned parameter change only while the foot switch is held down,
select “Moment” (momentary) instead.
In the case of numeric parameters, the maximum value doesn’t have to
be greater than the minimum value. In practice, this means that you’re
not limited to, say, moving the expression pedal forward to increase a
value, as you might in most cases; you can alternately move the pedal
forward to decrease a value instead, if you wish.
14
Continuous Controllers and the Active Range Settings
The Active Range settings on the ASSIGN screens are for realtime control
power users. They allow you to condense the active range of a continuous
controller when you’ve assigned it as a source, so that you can “tighten up”
the feel of the controller when it’s used.
For example, let’s say you’ve targeted a delay’s level to be controlled by the
onboard expression pedal, as we discussed above. By setting “ActRngLo”
and “ActRngHi” to values other than 0 and 127 respectively, you confine the
minimum and maximum value adjustment over a smaller pedal range when
the pedal is operated.
This principle is illustrated in the following diagram. Here, ActRngLo is set to
40 and ActRngHi is set to 80, while Min is set to 0 and Max is set 127.

Active Range settings are really only useful when the control source
is an expression pedal or input level. (Even then, the effect of Active
Range settings can be quite subtle.) For all other control sources—or if
you don’t want to set a smaller active range for an expression pedal or
input level source—we recommend setting ActRngLo to 0 and ActRngHi
to 127.

Quick Settings are also available for all the GT-10’s effects, making
it easy for you to instantly set up all the parameters in an effect at
one time. To learn more about using them, see the GT-10 Owner’s
Manual.
Setting Realtime Controllers to the Same Function for
All Patches
As we discussed earlier in “Patch Settings Versus System Settings,” you can
set each of the built-in and external pedals/switches to control the same
functions in all patches, ignoring the settings made in each individual patch.
Here’s how:
1
Press SYSTEM.
Turn the dial to select CONTROL, and then press ENTER.2
Use the 4 5 and 6 buttons to select the “Prefernc” line.
Turn the dial to select System.5
Use the 6 5 and 6 buttons to highlight the “Function “ line, and then
turn the dial to select a realtime control assignment. (If you don’t
want the realtime controller to control anything, select “Off.”)
7 5 and 6 buttons and dial to make the desired settings for
Use the
the assignment made in Step 6.
8
Repeat Steps 3-7 to make additional system settings as desired.
Press EXIT twice to return to the Play screen. 9
We mentioned this earlier, but it bears repeating: setting a control
assignment for system-wide use doesn’t affect the settings stored in
each patch; it only ignores them. To revert back to the settings stored
in each patch for a particular realtime controller, simply select Patch
in Step 5 above.
17
An Extra Onboard System-Wide Controller
The GT-10 has one more onboard system-wide controller we haven’t
mentioned yet: the number foot switch for the currently selected patch.
Assigning a Function to Be Controlled By a Numbered
Foot Switch
Press SYSTEM.1
Turn the dial to select PLAY OPTION, and then press ENTER.2
As you’re probably aware, GT-10 patches are organized in banks of four
patches each. Patches within the currently selected bank can be chosen
by foot using the four numbered foot switches on the front panel (shown
above). When a particular patch number (1-4) is selected, the LED on its
corresponding numbered foot switch lights.
As long as a particular patch is selected, its foot switch is idle. BOSS engineers
smartly recognized this, and they’ve given you the ability to assign your
choice of a few often-used functions to that idle switch.
If you’re not familiar with using the BANK and 1-4 switches to select
patch banks and patches on the GT-10, refer to the GT-10 Owner’s
Manual.
The following table shows the functions that are available for assignment.
Function What it Does
Off No assignment.
Tuner Turns the tuner on and off.
Ch. A/B Switches between Preamp CHANNEL A and B.
OD Solo Switches OD/DS SOLO on/off.
Solo Switches Preamp SOLO on/off for the currently
selected channel: A or B.
A&B Solo Simultaneously switches Preamp SOLO on/off for
both CHANNEL A and B.
Use the 3 5 and 6 buttons to select the “Num Pdl Sw” line.
Turn the dial to select a realtime control assignment. If you don’t 4
want a numbered foot switch to control anything, select Off.
5
Press EXIT twice to return to the Play screen.
To use the realtime control assignment you’ve just made, simply press the
numbered foot switch for the currently selected patch number (it’s the one
with the lit LED).
Carrying Over the Current Expression Pedal Value
While Switching Patches
If you use a particular expression pedal function in a number of different
patches—such as foot volume or wah—you may want to have the current
pedal position (and its subsequent controller value) carry over when
changing patches. This is accomplished with the Expression Pedal Hold
function.
18
Expression Pedal Hold is particularly useful when the expression pedal
is assigned to a volume function, such as foot volume or patch volume.
This eliminates volume jumps when switching between patches.
Press SYSTEM.1
Turn the dial to select PLAY OPTION, and then press ENTER.2
Use the 3 5 and 6 buttons to select the “Exp Pdl Hold” line.
Turn the dial to choose the desired setting: On or Off.4
Press EXIT twice to return to the Play screen. 5
At the GT-10’s factory default setting, the Expression Pedal Hold switch
is turned on.

while any ASSIGN screen is displayed.
Display Modes and Realtime Control Assignments
At the top of this booklet, and at various times throughout, we’ve talked a
bit about the GT-10’s different display modes. After you’ve made some of
your own control assignments—or if you just want to quickly see what’s
assigned in any patch—the following screen variations can help you quickly
see what’s assigned.
