ZOOM GFX-8

Introduction

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:

• 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.

Please take the time to read this manual carefully so as to get the most out of your GFX-8 and to ensure optimum performance and reliability. Retain this manual, the warranty card and all other documentation for future reference.

Terms Used in This Manual

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

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.

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.

User groups

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.

Connection Example (3) CD player/MD player connection

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.

The Quick Guide explains the basic steps for using the GFX-8 in play mode. This lets you use the unit right away, to check out what it can do.

Selecting the patch/bank number/group

In play mode, the name of the currently selected patch is shown on the display.

The group and bank number of the patch can be checked on the GROUP/BANK indicator.

Patch name Group Bank number

To switch the patch within the same bank, press one of the foot switches 1 - 4 whose LED is not lit.

* If you press the foot switch whose LED is lit, the GFX- 8 goes into the bypass condition.

To switch to a patch from another bank number or group, use the BANK

UP/DOWN foot switches and the foot switches 1 - 4 to select the bank number and group.

• For details on patch/bank/group switching, refer to p. 10.

To alter the effect with

RTM

RTM (real-time modulation) refers to changing an effect with the expression pedal in real time.

Rock the expression pedal back and forth.

Push the expression pedal fully down.

8

Move back and forth

The effect changes as the expression pedal is moved. The parameter that is controlled can be programmed for each patch. Try out this function to see which parameter changes for the stored patches.

Push fully down

The expression pedal incorporates a switch that operates when the pedal is pushed firmly down. The switch turns the module for which RTM control is possible on and off.

• For information on effects that allow RTM control, see p. 30.

• For more information on the use of the expression pedal, see p. 41.

Listening to Patches (Play Mode Operation)

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.

Panel Indication in Play Mode

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

(1) Patch name

(2) Group (U, u, A, b, C, d)

U and u are user groups,

A - d are preset groups.

(3) Bank number (0 - 9)

(4) When a dot (.) is shown here, the user group/preset group patches can be selected continuously.

(6) Lights up in red if the EQ module in the patch is ON.

(5) The foot switch LED of the currently selected patch lights up.

(7) When the LED is red, the effect is from group A, and when it is green, it is from group B.

When the LED is out, the effect is off.

Selecting a Patch

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.

User group

Preset group

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.

Using the Easy Edit Function

To edit patches of the GFX-8, the user normally will activate the edit mode, select the desired parameter, and change the setting.

However, it is also possible to switch effects in modules and change major effect parameters in play mode. This is called the easy edit function.

1.

To switch the effect used in the DRIVE, MOD, or

DLY/REV module, operate the selector and key for the respective module.

Select DRIVE module effect.

Select MOD module effect.

Select DLY/REV module effect.

2.

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

[EQ]

PRESENCE:

Adjusts boost/cut in the ultra-high frequency range.

TREBLE:

Adjusts boost/cut in the high frequency range.

MIDDLE:

Adjusts boost/cut in the medium frequency range.

BASS:

Adjusts boost/cut in the low frequency range.

[PARM knobs 1 - 4]

Adjust the following EQ module parameters.

Switches the respective module (DRIVE, MOD,

DLY/REV) ON and OFF and switches the group for selectable effects. With each push of the key, the unit cycles through the following three states.

Key out or slowly flashing red

Respective module is OFF.

Key lit/flashing red

Module is ON and effect from group A

(upper labels) is selected.

Key lit/flashing green

Module is ON and effect from group B

(lower labels) is selected.

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.

[GAIN knob]

Adjusts a major parameter of the DRIVE module. In almost all patches, this is the GAIN parameter that determines the distortion intensity.

[PARM SELECT/ADJUST knob]

Adjusts a major parameter of the MOD module.

[PARM VALUE/ADJUST knob]

Adjusts a major parameter of the

DLY/REV module.

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.

Parameter name Setting value

EDITED mark (.)

NOTE

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.

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).

NOTE

• 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).

Using the Bypass (Mute)/Tuner Function

The GFX-8 incorporates an auto-chromatic tuner for guitars. To use the tuner function, the built-in effects must be bypassed

(temporarily turned off) or muted (original sound and effect sound turned off).

1.

To set the GFX-8 to the bypass (mute) condition, press and immediately release the foot switch 1 - 4 that has selected the currently active patch (the foot switch whose LED is lit).

In play mode, when you quickly press the foot switch whose LED is lit, the GFX-8 switches to the bypass condition. The foot switch LED now flashes and the indication "BYPASS" is shown on the display.

3.

When the GROUP/BANK indicator shows the desired note, perform fine tuning while watching the display.

Pitch is low

Lit Flashes

ZOOM GFX-8

Adjusting the Reference Pitch of the Tuner

After the GFX-8 is turned on, the tuner reference pitch is always "center A = 440 Hz". If desired, you can change the reference pitch. This is useful for example to match your instrument to another instrument or sound source whose pitch cannot be changed easily, such as an acoustic piano or a CD. To do this, first change the reference pitch of the GFX-8 and then use to to perform tuning of your guitar.

1.

In play mode, press the foot switch 1 - 4 whose LED is lit, to set the GFX-8 to the bypass/mute condition.

The available setting range is "435" (center A = 435 Hz) - "445"

(center A = 445 Hz) in 1-Hz steps.

2.

Rotate the DLY/REV (PARM VALUE) knob to adjust the reference pitch. When this knob is operated, the current reference pitch is shown on the display. The initial setting is "440" (center A = 440 Hz).

3.

When tuning is completed, once more press the foot switch whose LED is flashing.


NOTE

When the GFX-8 is turned off and on again, the reference pitch will be reset to "440".

Switching Modules On and Off During Play (Manual Mode)

The condition where foot switches 1 - 4 can be used to switch the modules in a patch ON and OFF individually and where specific parameters can be adjusted is called "manual mode". In manual mode, the modules in a patch can be used like independent compact effects.

1.

In play mode, select a patch.

Changing the Sound of a Patch (Edit Mode)

The condition where you can change the parameters that make up a patch to create your own sound is called "edit mode". This section describes how to use edit mode.

Basic Edit Mode Steps

The basic steps that are normally taken in edit mode are explained here. Besides these, the edit mode also provides a short cut to quickly edit a specific parameter ( see page 16).

1.

In play mode, select the patch you want to edit.

The patch can be from a user group or preset group. However, because patches in the preset groups are read-only, after you have edited a patch, you can only select a user group patch as store target.

2.

Press the EDIT key.

The EDIT key LED lights up, and the GFX-8 enters the edit mode.

ZNR/EQ EDIT key

Selects the EQ module or ZNR.

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.

[GLOBAL] indicates a global parameter that applies to all patches.

Parameter 3 CT1-->XX xx:OF, 1 - 5, 7 - 31, 64 - 95

Sets the number of the control change (CT1) that is output from the MIDI OUT connector when the patch is switched at the GFX-

Using RTM

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.

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".

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.


"RTM MIN", and use the PARM VALUE knob to set the minimum value of the parameter.

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.


"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.


"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 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.

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.

Using the CONTROL Switch

1.

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.

Select the patch for which you want to use the

CONTROL switch.

The function assigned to the CONTROL switch is active in manual mode (and edit mode).

6.

Push 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 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.)

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.

NOTE

The actual function performed when pressing the

CONTROL switch depends on the module and effect (see page 19 - 29).

4.


5.

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

• 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

While the CONTROL switch is being pressed, the rate parameter of the flanger effect etc. becomes maximum.

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).

Controlling External Devices in Conjunction With GFX-8 Patch Switching

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).

To Send Only Bank Select + Program Change

Information

To Send Control 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.

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.

Remote Control Using GFX-8

It is possible to send out MIDI control change information whenever a control on the GFX-8 is operated, or conversely, to operate the GFX-8 via externally supplied control change information. This lets you for example record a GFX-8 operation sequence on a MIDI sequencer and play it back at any time. Remote control of the GFX-8 from other external equipment is also possible.

To control external equipment from the GFX-8, connect the MIDI OUT connector of the GFX-8 to the MIDI IN connector of the external device. To control the GFX-8 from external equipment, connect the MIDI OUT connector of the external device to the

MIDI IN connector of the GFX-8. (For information on enabling or disabling control change information output, please refer to "To

Bulk Dump

Patch information and program change map information stored in the GFX-8 can be output in bulk via the MIDI link. This function is called "bulk dump". You can use this function for example to store GFX-8 information on a MIDI sequencer or to exchange settings between two GFX-8 units.

1.

Connect the MIDI OUT connector of the GFX-8 to the

MIDI IN connector of the external MIDI device (other

GFX- 8, MIDI sequencer, etc.).

2.

Set the GFX-8 to play mode and turn the PARM

SELECT knob until the GROUP/BANK indicator shows

"15".

3.

Use the PARM VALUE knob to select the data type to use for the bulk dump operation.

After setting the external MIDI device to the recording mode, press the STORE key.

For example, when "ALL" was selected in step 3, the display shows "ALL OK?".

5.

To execute the bulk dump operation, press the

STORE key once more.

The display shows "DUMPING" and the GFX-8 starts to send the bulk dump data. To cancel the bulk dump operation, press the

EDIT/CANCEL key before pressing the STORE key the second time. The unit returns to the play mode without carrying out the operation.

6.

When the GFX-8 has returned to play mode, stop recording at the external MIDI device.

Perform any necessary steps to store the recorded information on the external MIDI device.

ZOOM GFX-8

Bulk Load

GFX-8 patch information or program change map information stored on external equipment can be reloaded into the GFX- 8.

This is called "bulk load".

1.

Connect the MIDI OUT connector of the external MIDI device (other GFX-8, MIDI sequencer, etc.) to the MIDI

IN connector of the GFX-8.

NOTE

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.

Perform playback at the external MIDI device.

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

NOTE

• 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.

3.

When bulk load is completed, stop playback at the external MIDI device.

When performing bulk dump or load with two GFX-8 units, hooking up both the MIDI IN and MIDI OUT connectors will result in faster data transfer.

Supplied Software

The GFX-8 comes with a CD-ROM that contains software for editing patches on a personal computer. (The disc contains versions for Windows 95/98 and Macintosh.) The software comprises the following functions.

(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.

Other Functions

This section contains information about special functions such as how to return the GFX-8 to the factory default condition and how to readjust the expression pedal.

All Initialize/Factory Recall

The All Initialize/Factory Recall function is a special function that lets you reset the GFX-8 to the condition in which it was originally shipped. When All Initialize is performed, all settings of the unit including all user group patches are returned to the default condition. Factory Recall can be used to reset only specific user group patches group to the default settings.

1.

Turn power to the GFX-8 on while keeping the STORE key depressed.

The display shows "ALL-INIT".
