Temporary Memory; Rewritable Memory; Non-Rewritable Memory - Roland XV-88 Owner's Manual

Temporary Memory

Temporary Area
This area holds data for the Performance, Patch, and Rhythm
Set you select using the front panel buttons.
When you play the keyboard or play back an external
sequence, sound is produced based on data in the temporary
area. When you modify a Performance, Patch, or Rhythm Set,
you are modifying the data that has been called into the
temporary area instead of the data in memory.
Settings in the temporary area are temporary, and will be lost
when the power is turned off or when you select another
Performance/Patch/Rhythm Set. To keep the settings you
have modified, you must write them into rewritable
memory.

Rewritable Memory

System Memory
System memory stores system parameter settings that
determine how the XV-88 functions. Any time you make
changes in the system parameters, such changes are
automatically stored in system memory (you don't need to
perform a save). These settings are non-volatile, so they are
retained even while the power is turned off.
User Memory
User memory is where you normally store the data you need.
User memory is capable of storing the data for 64
Performances, 128 Patches, and four Rhythm Sets.
Memory Card (SmartMedia)
Memory cards are read/write cards that allow you to save
the Patch, Performance, Rhythm Set, System and Favorite
List settings stored in the internal memory as one file (Save),
and return them as needed to the XV-88 (Load). You can use
memory cards to store data for which there is no room in
internal user memory, or data which you wish to use on
another XV-88.
Memory cards are not included. They are available from
your retailer.

Non-Rewritable Memory

Preset Memory
Data in Preset memory (Patch: PR-A–F, H, Performance: PR-
A, B, Rhythm Set: PR-A–F, H) cannot be rewritten. However,
you can call up settings from preset memory into the
temporary area, modify them and then store the modified
data in rewritable memory (except PR-H).
Wave Expansion Boards
(optional: SR-JV80/SRX Series)
The XV-88 can be equipped with up to four Wave Expansion
Boards (two SR-JV80 Series, two SRX Series). Wave
Expansion Boards contain Wave data, as well as Patches and
Rhythm Sets that use this Wave data, which can be called
directly into the temporary area and played.
