ZOOM GFX-1 3 Basic Terms This section explains some important terms that you will find in this manual. Effect module As shown in the illustration below, the effect sound of the GFX-1 is created by routing the signal through a series of different effects. Each of these effects is called an effect module. IN COMP WAH DRIVE EQ ZNR AMP MOD/PITCH DLY/REV OUT In addition to effect modules such as DRIVE (distortion), MOD/ PITCH (modulation), or DLY/REV (delay and reverb), you can also use the ZNR (Zoom Noise Reduction) and amp simulator simultaneously. Parameters such as effect intensity can be adjusted for each module, and modules can be switched on and off as needed. Effect type Each effect module of the GFX-1 contains a variety of effects in the same general family. These are called effect types, and you can select one of these at a time. For example, the MOD/PITCH module comprises the effect types chorus, flanger, pitch shifter, etc. Effect parameter Each effect module has various parameters that control how the effect operates. By adjusting the parameters for each module, you have a considerable amount of control over the final sound. Patch In the GFX-1, effects are stored and called up in patches. A patch contains information about module on/off settings, selected effect types, and effect parameter settings. The GFX-1 can store 40 patches in its internal memory. Bank A combination of 4 patches is called a bank. The GFX-1 has a total of 10 banks which are labelled A through J. The patches in each bank are numbered 1 through 4. To select a patch, you specify the bank and the patch number. A1 selects patch 1 in bank A, and F4 selects patch 4 in bank F. 4 ZOOM GFX-1 BANK J BANK i BANKPATCHPATCH 1 H1 BANK G PATCH 2 BANK F PATCH 1 2 1 BANKPATCHPATCHPATCHPATCHPATCH 3 E 2 1 3 BANKPATCH 1 d PATCHPATCHPATCHPATCH 4 2 3 BANK C 1 PATCH 2 3 BANKPATCHPATCHPATCHPATCHPATCHPATCHPATCH 4 b 2 4 1 3 BANKPATCH 1 A PATCHPATCH 3 2 PATCH 4 2 PATCH 4 PATCHPATCHPATCHPATCH 3 1 2 PATCH 4 3 PATCHPATCHPATCHPATCH 4 2 3 PATCHPATCHPATCH 4 3 4 PATCH 4 Play mode/edit mode These terms refer to the operation state of the GFX-1.
