Internal Memory and File Management

Internal Memory

● 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 permanently stored.

On the other hand, RAM (Random Access Memory) allows both reading and writing of data. This is the location for

the edit buffer data.

● Flash ROM and DRAM

The data contained in Flash ROM can be read and written and maintained indeﬁnitely, even if the power is off. This

is the location where the data created by editing is stored. 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 Flash ROM or a

memory card before turning off the power.

Never attempt to turn off the power while data is being written to Flash ROM (while an “Executing...” or “Please keep power on”

message is shown). Turning the power off in this state results in loss of all user data and may cause the system to freeze (due to

corruption of data in the Flash ROM).

Edit Buffer (DRAM) and Recall Buffer (DRAM)

● Edit Buffer and User Memory

The edit buffer is the memory location for edited data of these types: Voice, Performance and Master. Data edited in

this location will be stored to the User Memory.

If you select another Voice, Performance, Master, or Mixing setup, the entire contents of the edit buffer will be

rewritten with the newly selected Voice/Performance/Master/Mixing setup. 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

To properly protect and store your valuable User data, you should save it to Memory Card for indeﬁnite safekeeping

(page 82).

There are two different ways to save data created on the S90 to memory card:

• By saving all data in the User memory as a single ﬁle (with the extension “.W4A”).

• By saving the ﬁles separately according to their speciﬁc functions (with the extensions corresponding

to each type).
