INITIALIZING THE INTERNAL RAM
1. If the MANUAL button is held down while you turn the power on, the voice expansion board that is installed
will
automatically be detected, and internal RAM will be initialized for that expansion board.
If the CHAIN button is held down while you turn the power on, internal RAM will be initialized for the VE-RD1
regardless of whether or not a voice expansion board is present.
If the EDIT button is held down while you turn the power on, internal RAM will be initialized to the settings for
when an expansion board is not installed, regardless of whether a voice expansion board is present.
2. After turning on the power while holding down a button, press the ENTER button to execute the desired type
of initialization.
UPGRADING THE FLASH ROM SOFTWARE VERSION
The A-70 contains flash ROM, allowing the program version to be updated via MIDI.
Caution : If the power supply fails while flash ROM is being written into, the data in flash ROM will be
destroyed and it will be impossible to ever again rewrite it. If this occurs it will be necessary to
replace the ROM. Perform this operation in an environment where it is unlikely that the power to
the A-70 will be interrupted, or that other accidents could occur.

Necessary items
A-70/EX software update disk SMF player (SB-55 etc. Anything that will playback SMF will do.)
Foot pedal (DP-6) x 2 (or two mono dummy (=open)plugs are also ok.) MIDI cable
* The software update disk contains the A-70 program converted into SMF data. Obtain the latest version from
the service center. The
filenames are as follows.
_00001.mid
_00002.mid
:
_00008.mid
_00008.mid will always exist, and _00001 - _00007.mid may or may not exist depending on the program size.

Update procedure
0. As necessary, save the user memory to a sequencer. The contents of user memory will be lost during
the software update.
1. Connect pedals (or mono dummy (=open) plugs) to the HOLD and FS jacks of the A-70.
2. Connect the MIDI OUT of the SMF player to the MIDI *IN2* of the A-70.
3. Press both pedals (if you have inserted mono dummy plugs those connections will be sufficient), and
while holding down the OUT1 button turn on the power. The LCD will show as follows;

and the A-70 will enter software update mode.
4. Starting from the lowest-numbered filename, playback the files on the SMF player. (In the case of the
SB-55, playback will begin automatically from _00001.mid.)
During reception, the Receive Block / Top Address / End Address will indicate the current status.
* The Receive Block will indicate;
_00001.mid B1 (Block 1)
_00002.mid B2 (Block 2)
:
_00008.mid B8 (Block 8)
* The Receive Top/End Blocks will indicate;
_00001.mid FF0000-FFFFFF
_00002.mid FE0000-FFFFFF
:
_00008.mid F80000-FFFFFF
5. When each file has finished playing, pause the SMF player. (In the case of the SB-55, caution must be
used since the next file will begin to play.)
6. Check that the lower four digits of the Receive Top Address are 0000 and that the lower four digits of the
Receive End Address are FFFF. Then press the ENTER button of the A-70 to get a display like the
following.
Check sum display
After you confirm this by comparing the displayed value with the check sum printed on the disk label, press
the ENTER button and the software update will begin.
If the check sum is different, press the EXIT button to return to the display of step 3, and transmit the file
once again.
* When you press ENTER, the display will indicate
Erase -> Write -> CE9A-CE9A OK
During Erase or Write, be very careful to never let the power be interrupted. In the worst case, the A-70
may become incapable of starting up.
