Performing an Edit Compare
If you do not perform a store operation,
changes made to effects will be lost as soon
as another effect
within the same mode
(preset or register) is selected. Changing
between preset and register modes, how-
ever, will not erase your changes. This pro-
vides an edit compare capability which al-
lows you to toggle back and forth between an
effect you are working on and the original
version. For example:
1. Select a preset and store a copy of it in
any register.
2. Make any changes you want to either the
preset or the register.
3. Compare your new effect to the original
version simply by pressing the REGIS-
TER/PRESET button.
4. Use the REGISTER/PRESET button to
toggle back and forth as many times as
you like between the original effect and
the new version, making changes as de-
sired.
When you are satisfied with the effect,
perform a store operation to any register you
want using the procedure described on the
following page.
