Spirit Digital 328 offers non-destructive editing by using the UNDO/REDO function. This is useful for comparing new EQ settings or FX settings. Whenever functions have been updated, you can press the UNDO button to return to the original settings. To return to the
new settings, press REDO. There is only one level of UNDO/REDO to avoid confusion. Snapshots can be used if multiple levels of comparisons are required.
