ZOOM GFX-3 11 Changing the Sound of a Patch The patches of the GFX-3 can be modified by changing effect types and parameters. This section shows how to edit patches. INPUT COMP/ISO DRIVE EQUALIZER ZNR CABINET MOD REV/DLY OUTPUT Patch configuration Each patch of the GFX-3 consists of several effects (effect modules), as shown in the illustration above. A patch is a stored combination of modules, each with their distinct parameter settings. Within each module, there are several different but related effects which are called effect types. For example, the MOD (modulation) module comprises effect types such as CHORUS, PHASER, and WAH, of which one can be selected. The elements that determine the sound of a patch are called effect parameters. Each module has certain effect parameters, whose value can be adjusted with the effect module keys, PARAMETER keys, [VALUE] dial, etc. 1. Select the patch to edit. Patches for editing can be selected from either a preset group (A, b) or a user group (U/u). Patches from a preset group are read-only. If you have altered such a patch and want to keep it, you must store it in a user group (p.14 ). 2. To change the patch level, operate the [VALUE] dial. While the group/bank number indication is shown on the display, the [VALUE] dial can be used to adjust the patch level (final output level of the patch). When you turn the dial, the current patch level setting (1 - 30) appears on the display. A dot (.) in the bottom right of the display indicates that the patch has been edited. NOTE Also within the same module, different effect types will have different parameters. 3. If required, use the three selectors to choose the DRIVE, MOD, and REV/DLY module effect type. [DRIVE] selector Basic editing The most common steps for editing a patch are shown below. For a detailed description of effect types and parameters in each module, see the section "Effect Types and Parameters" on pages 17 - 22. [CLASSIC] key [STANDARD] key The distortion type of the DRIVE module is set with the [DRIVE] selector and the two module keys ([CLASSIC]/[STANDARD]). 12 ZOOM GFX-3 Changing the Sound of a Patch DRIVE module REV/DLY(Reverb/Delay) module MOD(Modulation) module EQ(Equalizer) module COMP/ISO (Compressor/Isolator) module ZNR/[TOTAL] module The effect type of the MOD and REV/DLY modules is set with the [MOD] selector and [REV/DLY] selector respectively. [MOD] Selector [REV/DLY] Selector The parameters that are assigned to the parameter keys for each module are printed on the panel. When the EQ module is selected, the parameter keys correspond to the following parameters. Parameters PRESENCE TREBLE 4. Use the module keys to select the module to edit.

Parameter 3 MASTER LEVEL Parameter 4 ENERGIZE 0 ­ 30 Adjusts the master level for all patches. oF, 1 ­ 30 Controls the Energizer setting that applies to all patches. Lower values result in stronger emphasis on treble, and higher values result in stronger emphasis on bass. The "oF" setting disables the Energizer. COMP/ISO (Compressor/Isolator) module The compressor serves to reduce excessive signal levels. The isolator allows cutting or emphasizing a particular band. Parameter 1 COMP/ISO Parameter 2 ATTACK/HIGH CO, IS Select the effect by choosing CO (Compressor) or IS (Isolator). The effect of parameters 2 - 4 differs, depending on which setting is chosen here. ATTACK (CO) FS, SL The time lag between signal input and start of compressor action can be set to FS (FAST) or SL (SLOW). HIGH (IS) oF, -12 ­ 12 Adjusts high-range mix. ZOOM GFX-3 17 DRIVE module Parameter 3 SENS/MID Parameter 4 LEVEL/LOW SENS (CO) 0 ­ 10 Adjusts compressor sensitivity. MID (IS) oF, -12 ­ 12 Adjusts mid-range mix. LEVEL (CO) 1­8 Adjusts signal level after passing module. LOW (IS) oF, -12 ­ 12 Adjusts low-range mix. DRIVE module This module comprises 20 types of distortion and acoustic simulator effects. Effect types are chosen with the [DRIVE] selector and the two module keys ([CLASSIC]/[STANDARD]).
