64 MOTIF Basic Structure
● ROM and RAM
ROM (Read Only Memory) is memory designed
speciﬁcally for reading out of data, and as such
data cannot be written to it. This is the location
where preset data for the instrument is
On the other hand, RAM (Random Access
Memory) allows both reading and writing of data.
This is the location for the edit buffer data and
data created by editing or recording.
● SRAM and DRAM
The MOTIF uses two different kinds of RAM ,
depending on the condition for storing the data:
SRAM (Static RAM) and DRAM (Dynamic
RAM). The data contained in SRAM is
maintained indeﬁnitely, unless the backup battery
(lithium battery; page 5) power is too low. On the
other hand, data contained in DRAM is lost when
the power is turned off. Because of this, you
should always store any data residing in DRAM
to a memory card or an external SCSI device
before turning off the power.
Edit Buffer (DRAM) and Recall
● Edit Buffer and User Memory
The edit buffer is the memory location for edited
data of these types: Voice, Performance, Master,
Song, Song Mixing, and Pattern Mixing. Data
edited in this location will be stored to the User
If you select another Voice, Performance, Master,
Song, or Pattern, the entire contents of the edit
buffer will be rewrittenwith the newly selected
Mixing data. Make sure to store any important
data before selecting another Voice, etc.
● Edit Buffer and Recall Buffer
If you’ve selected another Voice or Performance
without storing the one you were editing, you can
recall your original edits, since the edit buffer’s
contents are stored in backup memory. Keep in
mind that the recall buffer is available only in the
Voice or Performance mode.
Memory Card/External SCSI storage
To ensure that your data stored to User Memory are
maintained, it is the best way to save important data
to Memory Card or external SCSI device so that you
can keep them indeﬁnitely. See page 289 for details
about Memory Card and see page 27 for details about
There are two different ways to save data created on
the MOTIF to memory card or an external SCSi
• By saving all data in the User memory as a single
ﬁle (with the extension “.W2A”).
• By saving the ﬁles separately according to their
speciﬁc functions (with the extensions
corresponding to each type). See page 262
