It is important to note that Quick Editing changes the voice's characteristics — in
effect, it creates a new voice. If you like the new sound, you can store it as a separate
voice. ( BASICS: 3-28) If you do not like the editing results, you can cancel them by
pressing the original voice's program number (in the example above, number
), or by switching to a different voice.

Important
• Using a Quick Edit slider to increase the EQ gain may in some cases overload the
volume, resulting in output distortion. One way to correct this problem is to lower
the volume settings of the affected elements.
FYI
• When you first move a quick edit slider or press the Quick Edit panel's
an mark appears directly in front of the voice number displayed on the top line of the
LCD. This mark indicates that the voice has been edited. To cancel the results of editing
and remove the mark, reselect the same voice (by pressing the currently illuminated program
number).
