/ACCESSING & EDITING
THE PARAMETERS FOR EACH EFFECT
Each of the GEP50 effects has a number of internal parameters
which may be edited by you to create a sound that is ideally
suited to your own specific musical requirements. A complete
description of each effect and it? parameters is given in “3. DE­
SCRIPTIONS OF THE EFFECTS & THEIR PARAMETERS” ON
PAGE 13. Using effect 1 (Mid-Band Drive) as an example,
here’s how to access and edit effect parameters:
PARAM­
ETER
© Select and recall the effect to be edited (Mid-Band Drive for
this example).
Press the PARAMETER button and the first of the selected
effect’s parameters will appear on the bottom line of the
LCD. Each time the PARAMETER button is pressed, the
next parameter on the selected effect’s “parameter list” will
be called. With Mid-Band Drive, for example, the following
parameters are called in sequence:
DISTORTION ^ TREBLE MID FRO MID GAIN BASS
-4 TRG. LEVEL RELEASE ^ BALANCE ^ OUT LVL ^ and
back to DISTORTION
Note that the first parameter in the list is returned to if the
PARAMETER button is pressed after the last parameter
(OUT LVL in this example) has been called.
Once the desired parameter has been called, its value is
edited by using the and/or buttons. The button
increases (increments) the value while the button
decreases (decrements) the value. Either button can be
held down for continuous incrementing or decrementing.

New value
In this way you can go through and edit any number of the
parameters to create the sound you want. If, however, you
select and recall a new effect without first storing your ed­
ited parameters in a memory location between 51 and 00,
any changes you have made will be lost and will have to be
re-programmed. If you want to keep an edited effect, use
the STORE operation described below.
