COMPARING EDITED AND STORED VERSIONS
When you edit a Program or Mix, you are actually editing a copy which is in a
temporary edit buffer. Therefore, to retain the results of your edit, you must save it to
a particular memory location (see the next section on Storing). If you change memory
locations before saving, the buffer will be replaced and your edits lost.
Because the original Program/Mix remains undisturbed, you can compare the edited
version to the original by using the Compare function. You can only select Compare
mode when either Mix Edit, Program Edit or Effects Edit is selected, and the word
EDITED” appears in the lower-left section of the display (next to the Mix or
Program Mode indicator).
While in an Edit Mode (the word “EDITED” should appear in the lower-left
section of the display), press [COMPARE].
Both the [EDIT] button and the word “
EDIT” in the display will flash.
Press [COMPARE] again to exit Compare mode and return to the edited version.
Both the [EDIT] button and the word “
EDIT” in the display will stop flashing. Pressing
[MIX], [PROG], [GLOBAL], or [STORE] will also exit Compare mode. However, to
return to Compare mode after pressing one of these buttons, you must first press [EDIT]
and then press [COMPARE].
While Compare mode is selected, you can move around to view the various functions and
parameters, but you will not be able to edit anything. This is because you are seeing what is in
memory, not what is in the edit buffer.
PRESET MEMORY AND USER MEMORY
The QSR has three types of memory banks for Mixes and Programs: Preset, User and
Card. The Preset banks, of which there are four, are stored in ROM (Read Only
Memory), and therefore cannot be altered. However, the User bank, of which there is
1, is stored in RAM (Random Access Memory). Card banks can be either ROM or
RAM. Anytime you want to keep an edited version of a Mix or Program, you will
store it into the User bank or onto a RAM Card. If you want to permanently change a
Mix or Program that is in the Preset bank, you can store the edited version into the
User bank (in either the same number location or a different number location).
However, this requires that you “store over” an existing Program or Mix, losing
whatever was previously in that location. If you don’t want to lose any of the sounds
in the User bank, you should back-up the entire bank to either an external SRAM or
FlashRAM PCMCIA card, or (via MIDI System Exclusive) into a data storage device
or a MIDI sequencer. See Chapter 9 for more information on external storage
operations.
