Safety and Usage Precautions

USAGE AND SAFETY PRECAUTIONS

In this manual, symbols are used to highlight warnings and

cautions for you to read so that accidents can be prevented. The

meanings of these symbols are as follows:

Please observe the following safety tips and precautions to ensure

hazard-free use of the GFX-8.

• Power requirements

• The GFX-8 is powered by the supplied AC adapter .

• To prevent malfunction and safety hazards, Do not use any

other kind of AC adapter.

• When using the GFX-8 in an area with a different line

voltage, please consult your local ZOOM distributor about

acquiring a proper AC adapter.

• Environment

Avoid using your GFX-8 in environments where it will be

exposed to:

• Extreme temperature

• High humidity or moisture

• Excessive dust or sand

• Excessive vibration or shock

• Handling

Since the GFX-8 is a precision electronic device, avoid

applying excessive force to the switches and buttons. Also

take care not to drop the unit, and do not subject it to shock or

excessive pressure.

• Alterations

Never open the case of the GFX-8 or attempt to modify the

product in any way since this can result in damage to the unit.

• Connecting cables and input and output jacks

You should always turn off the power to the GFX-8 and all

other equipment before connecting or disconnecting any

cables. Also make sure to disconnect all cables and the AC

adapter before moving the GFX-8.

Usage Precautions

• Electrical interference

For safety considerations, the GFX-8 has been designed to

provide maximum protection against the emission of

electromagnetic radiation from inside the device, and protection

from external interference. However, equipment that is very

susceptible to interference or that emits powerful

electromagnetic waves should not be placed near the GFX-8, as

the possibility of interference cannot be ruled out entirely.

With any type of digital control device, the GFX-8 included,

electromagnetic interference can cause malfunctioning and can

corrupt or destroy data. Care should be taken to minimize the

risk of damage.

• Cleaning

Use a soft, dry cloth to clean the GFX-8. If necessary, slightly

moisten the cloth. Do not use abrasive cleanser, wax, or solvents

(such as paint thinner or cleaning alcohol), since these may dull

the finish or damage the surface.

Please keep this manual in a convenient place
for future reference.

Introduction

• Versatile array of effects

The Variable Architecture Modeling System (VAMS)

adapts the internal configuration of the unit to achieve

exactly the desired pattern. The GFX-8 provides 69

effects ranging from the sound of famous guitar

amplifiers and other vintage devices to ultra-modern

processing functions. Up to nine effects can be freely

combined for simultaneous use. Modulation effects and

delay/reverb effects allow up to two types of custom

settings to be stored in memory. Any desired setting can

be called up quickly and easily.

• Sophisticated distortion technology

Using new technology developed by Zoom, the GFX-8

can faithfully duplicate the characteristics of famous

guitar amplifiers and preamplifiers. The available

choices range from conventional overdrive to exciting

high-gain fuzz sound. In combination with the built-in

amp simulator and cabinet simulator, this lets you create

realistic distortion tailored to your music. Two types of

custom distortion are also included, letting you build

your own sound from scratch.

• "Easy Edit" feature

During a stage performance, quick editing is possible

using handy selectors and knobs on the top panel of the

unit. You can switch effects, adjust the 4-band equalizer,

control distortion gain, or fine-tune major parameters of

the delay/reverb effects. Operation is quick and intuitive,

just like using a compact effect device.

• MIDI capability

MIDI IN and OUT connectors are provided, allowing

you to hook up a MIDI sequencer or keyboard for

remote control, or to control a MIDI compatible guitar

amplifier or other device from the GFX-8. Memory data

can also be sent and received via the MIDI link.

• Supplied editing software

The GFX-8 is supplied with a CD-ROM containing

software that lets you manage and edit patch libraries on

a computer (Windows 95/98 or Macintosh). The

software also provides access to a user custom area for

detailed adjustments that are not possible on the main

unit.

• Extensive patch library

A patch is a combination of effects and parameter

settings stored in memory, with a name of up to 8

characters. The GFX-8 has room for 80 read/write

patches (4 patches x 20 banks) that can be freely

changed by the user, plus 160 preset patches (4 patches x

40 banks) that are read-only. In total, this gives access to

as many as 240 patches.

• Built-in sampler and jam play feature

The integrated phrase sampler has a recording time of up

to 25 seconds. In addition, there is a jam play feature that

lets you record a 12-second phrase and play it back in

normal, reverse, or scratch mode. Changing the playback

speed is possible without altering the pitch. This feature

comes in handy when copying phrases. The AUX input

lets you connect a stereo source such as a CD or MD

player, to combine with your session or to directly record

with the sampler.

• Designed for use on stage

The tough metal chassis of the unit will withstand use in

a demanding environment. The expression pedal and

foot switches are designed to facilitate your work on

stage. The easy-to-read 8-character display plus a 2-digit

LED panel are great for checking patch names, numbers,

and other settings at a glance. The output level can be set

to +4 dB to match professional specifications.

Thank you for selecting the ZOOM GFX-8 (hereafter simply called the "GFX-8 "). The GFX-8 is a sophisticated
digital effect processor with the following features and functions:

Naming of Parts

Modes

The GFX-8 has five different operation modes, as listed below.

•Play mode

In this mode, patches can be selected and played. This is the

default mode of the GFX-8 that is always active when power is

turned on.

•Manual mode

In this mode, you play your instrument while manually

switching modules on and off.

• Edit mode

In this mode, the effect parameters of the currently selected

patch can be edited (changed).

• Jam play mode

In this mode, you can record a guitar phrase and play it back in

normal, reverse, or scratch style.

• Sampler mode

In this mode, you can use the sampler function to record and

play back a phrase from guitar or a source such as a CD player.

RTM (real-time modulation)

This refers to changing effect parameters in real time. For example,

you can use the expression pedal to change the mix ratio of the

reverb sound, or adjust the delay time during a song using a MIDI

sequencer.

The type and range of the parameter to be changed, as well as the

controller type (expression pedal or MIDI control change

information) can be stored separately for each patch.

ZOOM GFX-8

Effect module

An "effect module" in the GFX-8 works like a stand-alone compact

effect device such as a distortion or delay. In the GFX-8, you can

use the four effect modules DRIVE, EQUALIZER, MOD, and

DLY/REV as well as the ZNR (Zoom Noise Reduction) + AMP

SIM (Amp Simulator) simultaneously.

Terms Used in This Manual

This section explains some important terms that are used throughout the GFX-8 documentation.

Effects and parameters

An effect is a specific processing function in a module. The effect

modules DRIVE, MOD, and DLY/REV each have 22 effects, from

which one can be selected. The various settings of an effect that

can be freely modified by the user are called parameters. The GFX-

8 uses two kinds of parameters: effect parameters which are stored

separately for each patch and global parameters which apply to all

patches.

Patch/group/bank

Effect module combinations and effect parameter settings are

stored in memory as "patches". The GFX-8 can store a total of 240

patches. These are divided into 80 read/write patches in the user

groups (U and u) and 160 read-only patches in the preset groups

(A, b, C, d). Each group has 10 banks numbered from 0 - 9, and

each bank has 4 patches which can be selected with the foot

switches 1 - 4 on the top panel of the unit.

Getting Connected

If your guitar amplifier is equipped with a power amplifier input

jack, you can directly connect the OUTPUT L/MONO jack of the

GFX-8 to the power amp input jack, using the GFX-8 as a guitar

preamplifier.

* When using the GFX-8 in this way, it is recommended to activate

the built-in amp simulator (see page 7).

A component with stereo line level output such as a CD player or MD

player can be connected to the AUX IN jack, using a stereo Y

cable. The signal supplied to this jack is not processed by the

effects of the GFX-8 and is sent directly to the OUTPUT jacks.

This allows you for example to listen to a CD while practicing a guitar

phrase.

* Using the sampler function of the GFX-8, it is also

possible to record the signal supplied to the AUX IN jack
(

see page 34).

* When using hi-fi equipment (mixer, audio system or

similar) instead of a guitar amplifier, activating the built-in amp
simulator (

see page 7) is recommended.

Listening to Patches (Play Mode Operation)

In play mode, the following information is shown on the panel.

Selecting and playing patches stored in the memory of the GFX-8 is called "play mode". The GFX-8 is always in this mode
immediately after being turned on. This section describes how to use the functions available in this mode.

ZOOM GFX-8

1.

To switch patches in play mode, press a foot switch 1

- 4 whose LED is not lit.

In play mode, foot switches 1 - 4 serve to select a patch from the

same group/bank. The LED of the currently selected foot

switch is lit.

2

To select a patch from a different group/bank, press
the BANK UP or DOWN foot switch to switch the
group/patch, and then use the foot switches 1 - 4 to
select the new patch.

For example, when the BANK UP foot switch is pressed

repeatedly, the group/bank number changes as follows.

The patch is not switched as long as you only switch the

bank/group (changed section of GROUP/BANK indicator

flashes). It is switched only after you press one of the foot

switches 1 - 4 (the flashing of the GROUP/BANK indicator

stops).

If desired, you can limit the action of the BANK UP/DOWN

foot switches to select only user group banks, or only

preset group banks. To do this, press the GROUP key.

With each push of this key, the selectable groups are

cycled as follows.

Listening to Patches (Play Mode Operation)

1.

To switch the effect used in the DRIVE, MOD, or
DLY/REV module, operate the selector and key for the
respective module.

When the effect is switched, the name of the new effect is shown on

the display for about 2 seconds. The EDITED mark (.) in the

GROUP/BANK indicator lights up. This indicates that an effect

parameter of this patch has been edited. The mark disappears when the

setting is changed back to the original setting.

While only the effect group was switched, the previous

effect is still active. The change does not occur until the

selector for the respective module is operated. Therefore

the selector position and the actual effect may differ

during this interval.

2.

To adjust a major parameter of each module, operate
the following knobs.

When one of the above knobs is moved, the display shows the

parameter name and the GROUP/BANK indicator shows the

parameter value for about 2 seconds.

Which parameter is assigned to the GAIN knob, PARM

SELECT/ADJUST knob, and PARM VALUE/ADJUST knob

depends on which effect is selected for that module (

see page 19 - 29).

• Trying to change effects or parameters which are set to

OFF in the current module has no effect. In this case,

the indication "OFF" is shown on the display.

• All changes made with the easy edit function are

temporary. Settings revert to the original condition when

the patch is switched. When wishing to keep the

changes, you must store the patch (see page 18).

5.

Use the PARM VALUE knob to adjust the value.

Parameters 9 - 12 are special parameters for custom distortion,

allowing setting characteristics separately for each frequency

band.

6.

Call up parameters 10 - 12 in the same way with the
PARM SELECT knob, and use the PARM VALUE knob
to adjust the value.

7.

When you have created a custom distortion effect,
store the patch.

That parameters 9 - 12 are global parameters that affect all

patches. For example, when parameters 9 - 12 of custom

distortion 1 in a patch were adjusted, and the patch was

stored, the changes will affect all patches using custom

distortion 1 (effect type 11A).

NOTE

NOTE

The effect numbers 11A and 11B of the DRIVE module are reserved for custom distortion effects created by the user. For custom
distortion, in addition to the regular effect parameters (PARM1 - PARM8), there are four more parameters (PARM9 ­PARM12) which allow control over the distortion character and other characteristics.

ZNR/EQ (Zoom Noise Reduction/Equalizer) Module

This module contains the ZNR (Zoom Noise Reduction) function that reduces noise during pauses, and an equalizer for
adjusting the spectral balance of the sound.

(

Zoom Noise Reduction

)

This circuit achieves noise reduction during play pauses without
affecting the character of the sound.

Adjusts the ZNR sensitivity. Select the setting that yields best
noise reduction without causing the sound to become unnatural.
When set to "oF", the ZNR action is defeated.

(Equalizer Page 1)

This is page 1 of the four-band equalizer that serves to tailor the sound.
There is only one equalizer effect, but because it has many parameters,
the settings are divided into two pages (EQ P1/EQ P2) for operation

SFX Effects

If one of the SFX effects below is set to ON in the DLY/REV module, the MOD module becomes inactive.

Common Parameters of SFX Effects

Adjusts the predelay time.

Adjusts the effect mix ratio.

Adjusts the picking detection sensitivity for
wah and the trigger sensitivity.

This is a sampler effect with up to 25 seconds of record/play time. For
details on operation, see the section "Using the Sampler" (see page 34).

Selects the recording source as follows.

PL: Guitar signal from INPUT jack
AU: Stereo line signal from AUX IN jack

HINT:
When PL is selected, the signal is recorded after passing
the EQ module. When AU is selected, the signal is
recorded without passing any effect modules.

This parameter determines whether pitch compensation is
performed when playback speed is changed. Available settings
are "on" (compensation on) and "oF" (compensation off).

Selects the playback speed.

When pitch compensation was not selected with the PITCH
parameter, the pitch of the playback sound changes as follows
according to the SPEED parameter.

Adjusts the playback tone. Settings from -10 to -1 mean a low­range cut and settings from 1 to 10 a high- range cut.

NOTE:
While the sampler function is used, the expression pedal
always operates as volume pedal for the input/playback
signal. Therefore the SAMPLER effect does not have an
RTM parameter.

Switches the sampler function on and off.

This is a combination effect of auto-wah and tremolo.

Adjusts the auto-wah sensitivity. When set to a negative value,
the wah effect operates in the downward direction.

Adjusts the time lag between the input signal and the start of the
tremolo effect. When the setting is "oF", the effect is always
operating.

Adjusts the tremolo effect depth.

Adjusts the tremolo modulation rate.

TOTAL Module

The TOTAL module is not a separate effect module but rather the section of the unit where patch level and patch name information
as well as global parameters common to all patches are stored.

Because the TOTAL module has a high number of parameters, the

settings are divided into 3 pages.

(Page 1)

Adjusts the overall patch output level. A setting of 40 results in
the unity condition (input level = output level).

PARM knobs 2 and 3 are used to input or change patch names.
Use the PARM knob 2 or PARM SELECT knob to specify the
character input position (flashing point on display), and use the
PARM knob 3 or PARM VALUE knob to select the character or
numeral. The following alphanumeric characters can be used.

(Page 2)

Using RTM

The parameter to be controlled by RTM as well as the control

range can be freely set in edit mode. The steps for setting up and using

RTM are as follows.

1.

In play mode, select a patch for which RTM is set.

2.

Switch to edit mode, and use the DRIVE, ZNR/EQ
EDIT, MOD, DLY/REV keys to select the module to be
controlled by RTM.

3.

Turn the PARM SELECT knob until the display shows
"RTM CTL".

RTM CTL is the parameter that selects the controller for the

RTM action. The following settings are possible.

• oF

RTM is not used in the module.

• Pd

RTM is controlled with the expression pedal on the unit.

•1 - 5, 8 - 31

RTM is controlled with the MIDI control change of the

respective control number.

4.

Turn the PARM VALUE knob to select "Pd".

The respective module can now be controlled with the

expression pedal.

5.

Turn the PARM SELECT knob until the display shows
"RTM DES".

RTM DES selects which effect parameter in that module is

controlled by RTM.

6.

Turn the PARM VALUE knob to select the number of
the parameter (1 - 4) to be controlled by RTM.

7.

Turn the PARM SELECT knob until the display shows
"RTM MAX", and use the PARM VALUE knob to set
the maximum value of the parameter.

For the effect parameter selected in step 6, RTM MAX

determines the maximum value that is established when the

expression pedal is pushed fully down (or when the value of the

received MIDI control change is 127).

Taking the maximum value of the controlled parameter as 100

(%), the setting can be made from 0% - 100% (setting value = 0

- 99, 1.0).

8.

Turn the PARM SELECT knob until the display shows
"RTM MIN", and use the PARM VALUE knob to set the
minimum value of the parameter.

For the effect parameter selected in step 6, RTM MIN

determines the minimum value that is established when the

expression pedal is fully raised (or when the value of the

received MIDI control change is 0).

Taking the maximum value of the controlled parameter as 100

(%), the setting can be made from 0% - 100% (setting value = 0

- 99, 1.0).

It is also possible to set RTM MIN to a higher value than

RTM MAX. For example, if the setting is RTM MAX = 0,

RTM MIN = 1.0, the parameter for that module becomes

smaller as the pedal is pushed and maximum when the

pedal is raised.

9.

Repeat steps 2 - 8 to make the RTM setting for other
modules in the same way.

The RTM parameters described above are available separately for

the DRIVE, EQ, MOD, DLY/REV modules. This makes it

possible to control several parameters in different modules

simultaneously.

It is also possible to assign the volume control to the

expression pedal. This setting is made with the VOL_RTM

parameter (see page 29) in the TOTAL module.

10

.

Store the patch and return to play mode.

When the expression pedal is operated in this condition, the

assigned parameter changes within the preprogrammed range.

When the parameter was set to MAX=1.0 (100%), MIN=0

(0%), the expression pedal changes the parameter as follows.

HINTHINT

The RTM (real-time modulation) function can be operated either with the expression pedal on the top panel or by MIDI
control change messages input via a MIDI link. This can be used for example to change the reverb sound mix ratio during a
performance, using the expression pedal, or to control effect parameters during play, using a MIDI sequencer.

Using RTM

30

ZOOM GFX-8

Using RTM Using the CONTROL Switch

When the parameter was set to MAX=0 (0%), MIN=1.0

(100%), the expression pedal changes the parameter as

follows.

11.

To switch the effect module being controlled by RTM
on and off, push the expression pedal fully down.

The expression pedal of the GFX-8 incorporates a push- down

switch that is activated when the pedal is pushed fully down in

play mode. The switch serves to turn the RTM controlled

module on and off.

For example, use the edit mode to set the DRIVE and

MOD modules to RTM control, so that one module is on

and the other module is off, and store the patch. When

you call up this patch in play mode, you can switch

between RTM control of the two modules each time you

fully depress the expression pedal.

HINTHINT

Parameter value

When the GFX-8 is in manual mode or edit mode, the CONTROL switch (foot switch 4) can be used for real-time control. If you
program the module to be controlled beforehand, you can for example use the CONTROL switch during a performance to boost
the DRIVE module or to input the delay time with tap input.

31

ZOOM GFX-8

Using the CONTROL Switch

1.

Select the patch for which you want to use the
CONTROL switch.

2.

Press the TOTAL key twice, so that the LED is flashing
green.

3.

Use the PARM knob 2 to assign a module to the
CONTROL switch.

While the TOTAL key is flashing green, turning the PARM

knob 2 sets the CT SW parameter which selects the module to

assign to the CONTROL switch.

The following settings are available.

•oF CONTROL switch is not active for this patch.

•dS CONTROL switch controls DRIVE module.

•Eq CONTROL switch controls EQ module.

•Md CONTROL switch controls MOD module.

•rv CONTROL switch controls DLY/REV module.

The actual function performed when pressing the

CONTROL switch depends on the module and effect (see

page 19 - 29).

4.

Store the patch and return to play mode.

5.

Hold the BANK DOWN key down for at least 1 second
to activate the manual mode.

The function assigned to the CONTROL switch is active in

manual mode (and edit mode).

6.

Push the CONTROL switch.

The function assigned to the CONTROL switch in that patch can

be carried out. (For each effect, one of the following functions is

assigned. This assignment is fixed and cannot be changed.)

• Boost on/off

The switch serves to further boost the DRIVE module. This

function can be used for all effects in the DRIVE module.

•Module bypass/Mute

While the CONTROL switch is being pressed, the module

effect is bypassed. Can be used for the EQ module and

some effects of the MOD and DLY/REV modules.

• Tap input

The delay time setting can be made (edited) by pressing the

CONTROL switch in the desired interval. Can be used for

delay effects in the MOD and DLY/REV modules.

• Parameter value increase/decrease

Basic MIDI Send/Receive Settings

MIDI Usage Examples

Switching GFX-8 Patches From an External Unit

35

ZOOM GFX-8

MIDI Usage Examples

You can send MIDI messages from an external MIDI device to the

GFX-8 and switch patches at the GFX-8 in this way. To do this,

connect the MIDI OUT connector of the external MIDI device to the

MIDI IN jack of the GFX-8, using a MIDI cable. Set the MIDI

send channel at the external MIDI device and the MIDI receive

channel (RXCH) at the GFX-8 to the same settings.

To switch patches, you can either use bank select + program

change information to switch the patch directly, or you can use the

program change map built into the GFX-8 to call up patches

indirectly.

Specifying Patches Directly

You can use bank select + program change messages to directly

specify any group, bank number, and patch number of the GFX-8.

Proceed as follows.

1.

In play mode or edit mode, press the MIDI key.

The MIDI key lights up, and the unit enters the MIDI utility

mode.

2.

Turn the PARM SELECT knob so that the
GROUP/BANK indicator shows "14".

The display shows "PC FIX" or "PC MAP".

3.

If necessary, use the PARM VALUE knob so that the
display shows "PC FIX", and then press the EDIT key .

The GFX-8 returns to the play mode.

4.

To switch GFX-8 patches under external control, send
messages in the following order.

• Bank select MSB (control change number: 0/value: 0)

• Bank select LSB (control change number: 32/value: 0 - 2)

• Program number (0 - 79)

The relationship between GFX-8 patches and bank select

MSB/bank select LSB/program number is as shown below.

Item name setting value Item number

MIDI Usage Examples

• Always use the sequence: bank select MSB, bank

select LSB, program number. If the order is changed or

if another message is inserted, the GFX-8 may

disregard the command.

• When bank select information is omitted and the GFX-8

receives only a program number, it will use the last

received bank select (default settings: MSB = 0,

LSB = 0).

Specifying Patches Via PC Map

The GFX-8 incorporates a so-called program change map that

maps MIDI program numbers to GFX-8 patches. Using the

program change map, you can make program change numbers 0 - 127

call up any desired patch.

1.

In play mode or edit mode, press the MIDI key.

The MIDI key lights up, and the unit enters the MIDI utility

mode.

2.

Turn the PARM SELECT knob so that the
GROUP/BANK indicator shows "14".

The display shows "PC FIX" or "PC MAP".

3.

Turn the PARM VALUE knob until the display shows
"PC MAP".

The program change map is now active.

4.

Next, turn the PARM SELECT knob until the
GROUP/BANK indicator shows "PC".

The program change map is selected as setting item. The

display shows the MIDI program number (P000 - P127) and the

group (U, u, A, b, C, d), bank number (0 - 9), and patch

number (1 - 4) assigned to that number.

5.

Turn the PARM SELECT knob to select the program
number to assign to the patch.

When the above display has appeared, you can turn the PARM

SELECT knob to change the program number.

MIDI Usage Examples

To Send Only Bank Select + Program Change
Information

To set up the GFX-8 so that it sends bank select information +

program change information corresponding to a patch, proceed as

follows. This is useful for example to switch programs at a MIDI

compatible amplifier or effect device when a patch is switched at the

GFX-8.

1.

In play mode or edit mode, press the MIDI key.

The MIDI key lights up, and the unit enters the MIDI utility

mode.

2.

Turn the PARM SELECT knob so that the
GROUP/BANK indicator shows "04".

The display shows "PCOUT ON" or "PCOUT OF".

3.

If required, turn the PARM VALUE knob so that the
display shows "PCOUT ON", then press the EDIT key.

The program change output is now enabled, and the GFX-8

returns to the play mode.

4.

Switch a patch at the GFX-8. The bank select MSB,
bank select LSB, and program change corresponding
to that bank is output.

For information on the relationship between GFX-8 patches

and bank select MSB/bank select LSB/program number, see

the table on page 36.

To Send Control Change Information

Besides pedal and foot switch operation, the GFX-8 can be set up so

that it sends two types of control change information (called CT1 and

CT2) immediately after sending bank select + program change

information when a patch is changed. The control number and

value of CT1 and CT2 can be defined freely and stored separately for

each patch. For example, this is useful to control the volume setting at

a MIDI compatible amplifier or synthesizer.

1.

In play mode or edit mode, press the MIDI key.

The MIDI key lights up, and the unit enters the MIDI utility

mode.

2.

Turn the PARM SELECT knob so that the
GROUP/BANK indicator shows "05".

The display shows "CTOUT ON" or "CTOUT OF".

3.

If required, turn the PARM VALUE knob so that the
display shows "CTOUT ON", then press the EDIT key .

The control change output is now enabled, and the GFX-8

returns to the play mode.

This setting affects all control change output operations of

the GFX-8.

6.

Turn the PARM VALUE knob to select the group, bank
number, and patch number to assign to the currently
shown program number.

You can use the BANK UP/DOWN foot switch and foot

switches 1 - 4 to specify the respective group, bank number, and

patch number.

7.

Repeat steps 5 and 6 until all desired program
numbers have been mapped to their respective
patches.

If desired, you can also assign several program numbers to the

same patch.

8.

When the entire assignment process is completed,
press the EDIT key.

The program change map is stored, and the unit returns to the

play mode.

9.

Send a program change message from the external
MIDI device.

The patch assigned to the program number will be called up.

• When using the program change map, there is no need

to send bank select information from the external MIDI

device.

• The program change map is active only for receiving

MIDI messages. The program number information sent

by the GFX-8 when patches are switched is fixed (see

page 36).

When you switch a patch with the controls on the top panel of the GFX-8, the unit can send program change information and
control change information to an external MIDI device. To do this, connect the MIDI OUT connector of the GFX-8 to the MIDI IN
jack of the external MIDI device, using a MIDI cable. Set the MIDI send channel at the GFX-8 and the MIDI receive channel (RXCH)
at the external MIDI device to the same settings.
This function of the GFX-8 can be set up in two ways, as follows:
GFX-8 sends only bank select information + program change information when the patch is switched GFX-8 sends bank select
information + program change information followed by two types of control change information (CT1 + CT2).

Example:
Control number 70 is assigned to DRIVE module on/off

When the DRIVE module is switched on or off at the GFX-8

itself, the MIDI OUT connector supplies the following control

change information: control number = 70, value = 127/0.

When the control change information "control number = 70,

value = 127/0" is supplied to the GFX-8 MIDI IN connector, the

DRIVE module is switched OFF. When the control change

information "control number = 70, value = 64 - 127" is supplied, the

DRIVE module is switched ON.

While the jam play function or sampler function is

activated, external MIDI control is not possible.

NOTE

Patch information and program change map information stored in the GFX-8 can be output in bulk via the MIDI link. This function

To perform bulk load, the GFX-8 must be set to the same

MIDI channel as used when performing bulk dump. If the

MIDI channel is different, playback at the external MIDI

device will have no effect and will be disregarded by the

GFX-8. When the GFX-8 is in store mode, received bulk

data will be disregarded. Verify that the unit is not in store

mode before proceeding.

2.

The settings of the GFX-8 are overwritten, depending on the type

of received data.

• When saving data on an external device and when

reloading the data to the GFX-8, the GFX-8 must be set

to the same MIDI channel. If the MIDI channel is

different, playback at the external MIDI device will have

no effect and will be disregarded by the GFX-8.

• Playback at the external MIDI device must be performed

at the same tempo as recording. If the tempo is faster,

the GFX-8 may not receive the data properly.

MIDI Usage Examples

(1) Patch librarian

Serves to manage patch information of the GFX-8 on the

computer. Information about all patches of the GFX-8 is sent to

the computer via a MIDI link and can be stored on the hard disk

as a project file. Within a project, the order of patches can be

changed, and information stored as project files can be loaded

back into the GFX-8. In effect, this increases the memory

capacity of the GFX-8 to an unlimited size.

(2) Visual editor

Using knobs, switches and other graphical elements appearing on

the computer screen, patches contained in project files can be

edited. Because the edited contents are sent immediately to the

GFX-8 via the MIDI link, the effect of any editing operation can

be checked immediately by listening to the sound. Edited

patches can be stored on the computer and can also be sent to the

GFX-8 via the MIDI link.

(3) DRIVE module custom setting editor

Using this software, you can edit additional parameters for the

DRIVE module custom settings, to achieve even more detailed

adjustments than are possible with the controls on the unit

itself. There are virtually no limits to your creativity, as you

can set numerous items such as balance for each frequency

band, distortion circuit characteristics, etc. The editing results can

be written back to the GFX-8.

• For information on software installation, please refer to
the separate sheet. For information on how to use the
software, please refer to the documentation included on
the CD-ROM.

• The latest version of the software can be downloaded
from the Zoom web site.
