4.9 Presets Group
This group of switches handles memory and program related tasks.
SAVE Switch The SAVE switch saves the contents of the edit
buffer to the selected memory location. The
SAVE
switch flashes if the edit buffer has been modified
(is dirty) and memory protection has not been
enabled. If the edit buffer is clean and memory
protection disabled, the LED illuminates steadily.
The LED is off when program memory is protected.
When memory protection is on, trying to save the
edit buffer displays the
Prt
(protected) message.
With memory protection off, a long press saves the
edit buffer using the currently displayed program
number (number seen when not in edit mode). The
display shows
donE
after the save operation has
completed. Remember that program numbers
above 128 are reserved and always write protected.
The following table shows the effects of memory protection, the edit buffer state, and the
SAVE
switch.

COMPARE Switch The COMPARE switch toggles the 601's settings
between those stored in the edit buffer and those
stored in program memory. This allows making
quick a/b comparisons between the original
program and the current settings. The display
toggles between
OLD and CURR to help you keep
things straight.
LOAD Switch The LOAD switch loads a copy of the program
whose number currently shows in the display into
the edit buffer for editing. The display reads
donE
when the operation is complete.
LOAD Switch (cont’d) If the program number has been changed with the
Wheel, the
LOAD switch LED and the preset
number shown in the display flashes, indicating
that a new program is available for loading. If the
program number has not been changed, but you
still want to load the original program over the
current edit buffer (i.e. start over), holding down
the
LOAD button forces a load operation. In either
case, the display shows
DONE when complete.
