RESTORING THE FACTORY
SETTINGS
If there is important data you've created that's stored in the RS-70's internal
memory, you must note that all such data will be discarded when a Factory
Reset is performed. If you want to keep the existing data, save it on a disk
(Saving the entire user memory).
Be sure not to turn off the power while Factory Reset is being performed.
If the power is turned off or interrupted while data is being written to
memory, the internal data may become corrupted, and you may not be able to
turn the power back on.
Procedure
1. Press [PATCH] button so it is lit and you are in Patch mode.
2. Press [UTILITY] button so it is lit.
3. Use PAGE/CURSOR [<]/[>] button to select “5:FACTORY RESET.”
FACTORY RESET3.eps
4. Press [ENTER] button.
FACTORY RESET1.eps
5. Press [ENTER] button again to execute the Factory Reset.
The Factory Reset operation will require several minutes.
Do not turn off the power while the screen indicates “KEEP POWER ON !”
The operation will be completed in less than five minutes.
FACTORY RESET5.eps
6. When the display indicates “COMPLETED”, the factory reset operation
has been completed.
SYSTEM SOFTWARE UPDATE
PROCEDURE
Overview
• The RS-70 uses 32 Mbit flash memory to store its control program.
• The flash memory updater (control program) is stored in the updater
block of the flash memory.
• Normally, the data for the update is provided in the form of binary data
or SMF data divided into two or more parts.
If using binary data to perform the update, the program version can be
updated by loading the binary data from the floppy disk drive of the RS-70.
If using SMF data to perform the update, the program version can be updated
by connecting a sequencer (e.g., MC-80) capable of playing back SMF data to
the RS-70, and loading the data into the RS-70.
After you update the system, you will need to perform the Factory Reset
procedure.
Since this will reset the user data, you will need to back up the user data
beforehand.
Details are given in “Saving and loading data.”
Updating via the floppy disk
drive
(Turnaround time of updating
about 2 minutes and 30 second)
Required items
• Binary data update disks (2HD x 3 disks): P/No.17041310
These disks contain the following files.
The file name will be the same even if the version changes.
RS-70 Binary Update Disk #1(1/3)
RS70A.BIN
RS-70 Binary Update Disk #2(2/3)
RS70B.BIN
RS-70 Binary Update Disk #3(3/3)
RS70C.BIN
Procedure
1. While holding down the [KEY MODE] button and the [ENV or
BALANCE/LFO] button, turn on the power. (Continue holding down
the [KEY MODE] button and the [ENV or BALANCE/LFO] button until
the following screen appears.)
floppy disk drive1.eps
2. Press the [2](KBD&ORG) button.
floppy disk drive2.eps
3. Insert RS-70 Binary Update Disk #1 in the floppy disk drive and press the

When RS-70 Binary Update Disk #3 has been processed, the following
screen will appear, and the [1](PIANO) button and [2](KBD&ORG)
button LEDs will blink.
floppy disk drive5.eps
6. Verify that “****” matches the checksum of the updated version.
Turn off the power of the RS-70, turn the power on again, and perform
the Factory Reset operation. (See “Factory reset.”)

Updating via SMF data
(Turnaround time of updating
about 25 minutes)
Required items
• A sequencer that is able to play back SMF data (a sequencer with Chain
Play capability is ideal; e.g., the MC-80)
• MIDI cable
• SMF data update disks (2HD x 3 disks): P/No.17041309
These disks have the following names.
RS-70 SMF Update Disk #1(1/3)
RS-70 SMF Update Disk #2(2/3)
RS-70 SMF Update Disk #3(3/3)
The three disks contain SMF files named p000XX.mid (XX is a
consecutive number starting with “01”; the number of files will depend
on the version). Play back these files in numerical order.
Procedure
1. Connect a MIDI cable from the MIDI OUT of your external sequencer to
the MIDI IN of the RS-70. If your sequencer has Chain Play capability,
make settings to chain-play the SMF files.
2. While holding down the [KEY MODE] button and [ENV or BALANCE/
LFO] button, turn on the power. (Continue holding down the [KEY
MODE] button and [ENV or BALANCE/LFO] button until the following
screen appears.)
SMF1.eps
3. Press the [1](PIANO) button. The screen will indicate “Waiting,” and the
RS-70 will wait to receive MIDI data.
SMF2.eps
4. Verify that the RS-70 is waiting to receive MIDI data, and then play back
all “.mid” files on the RS-70 SMF Update Disks in numerical order.
While MIDI data is being received, the [NUMERIC] button LED will
blink, and the “Waiting” indication will change to “Receiving.”
When the data of one file has been transferred, the indication will change
to “Waiting”; play back the next file. The update process will be easier if
you use a sequencer that has a Chain Play function, such as the MC-80.
5. When the update is completed, following screen will appear, and the
[1](PIANO) and [2](KBD&ORG) LEDs will blink.
SMF3.eps
6. Verify that “****” matches the checksum of the updated version.
7. Turn off the power of the RS-70, turn the power on again, and perform
the Factory Reset operation. (See “Factory reset.”)
