Here’s how to back up (save) all settings of the RS-50 on an external MIDI
sequencer.

Procedure

1. Use a MIDI cable to connect the RS-50’s MIDI OUT to the MIDI IN of

your sequencer.

2. Press the [PATCH] button to make it light, entering Patch mode.

3. Press the [UTILITY] button to make it light.

4. Use the [PAGE/CURSOR < ] / [PAGE/CURSOR > ] buttons to select

“4:XFER to MIDI.”

RESTORING THE FACTORY SETTINGS

If there is important data you've created that's stored in the RS-50'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."

6. When the display indicates "COMPLETED", the factory reset operation

has been completed.

UPDATING THE SYSTEM

Overview

• The RS-50 uses 16 Mbit flash memory to store its program.

• The flash memory updater (control program) is stored in the updater

block of the flash memory.

• The data for the update is normally provided as SMF data. Connect a
sequencer that is able to play back SMF data (e.g., the MC-80) to the RS­50, and load the data into the RS-50 to update its program.

COMPLETED
Test Mode End

• When this screen appears, the procedure has been completed. Turn off
the power.

16

• After you update the system, you will need to perform the Factory Reset.
Since this will also reset the user data, you must back up the user data
beforehand. (Refer to “Saving and loading data”)

Turnaround time of updating
about 20 minutes

Required items

• Sequencer that is able to play back SMF data (e.g., MC-80; a sequencer
that has Chain Play capability is ideal)

• MIDI cable

• Disks containing the SMF update data (2HD x 2): P/No.17041315

The disks are named as follows.

RS-50 SMF Update Disk #1 (1/2)

RS-50 SMF Update Disk #2 (2/2)

The two disks contain files named p000XX.mid, where XX is a
consecutive number starting from “01”. (The number of files will depend
on the version.) Play back these files in their numerical order.

Procedure

1. Connect the MIDI from your external sequencer’s MIDI OUT to the RS-

50’s MIDI IN. If you are using a sequencer with Chain Play capability,
make settings so that you can 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 buttons
until the following screen appears.)

Update-01

RS-50

Select Menu:
1:MIDI 2:SUM

3. Press the [1](PIANO) button. The display will indicate “Preparing...” for

several seconds, then “Waiting...”, and will wait to receive MIDI data.

Update-02

Waiting...
[________________]

4. When the RS-50 indicates that it is waiting to receive MIDI data, play back

all of the “.mid” files from the RS-50 SMF Update Disks in numerical
order. While the RS-50 is receiving MIDI data, the “Waiting” indication
will change to “Receiving.” When the data of one file has been received,
the indication will change to “Waiting”; you can then play back the next
file. The update process will be easier if you use a sequencer that has
Chain Play capability, such as the MC-80.

5. When the update is completed, the following screen will appear and the

[1](PIANO) and [2](KBD&ORG) LEDs will blink.

Update-03

INT:160B (160B 160B)
EXT:**** (****) xxxx

6. Verify that “****” matches the checksum of the version to which you

updated.

7. Turn off the power of the RS-50. Then turn the power on again and

perform the Factory Reset operation. (Refer to “Factory reset”)

8. If the update failed, perform it once again from step 1.

Use screws which TAPTIGHT P 3X8MM ZC(#40011312) to fixed SIRCUIT BOARD in SK-9.

1) Turn over the keyboard as shown in Flg. 1 . Place the RUBBER SWITCH 12P on 4 chassis, from the left (lowest note) upward, with respect to slots in the chassis.
Make sure that each switch is aligned with corresponding air groove in the chassis(Fig.2). Similarly, Place the RUBBER SWITCH 13P on the right section (high note)
chassis.
