The JP-8080 is equipped with a flash memory allowing updates
of the program version from MIDI.
Update disk : 17048696 JP-8080 Ver.UP DISK
◆ WARNING!!
READ THIS BEFORE STARTING THE VERSION UPGRADE:
(1)The JP-8080 might not start up if mistakes are made in the
version upgrade procedure or the power is cut during
operation. Always comply with the procedure listed below
and PLEASE! never turn off the power during operation.
(2)The user data area is used as the job memory during the
version upgrade. This means that user data will be
deleted. Be sure to make a backup copy of the user data
before attempting the version upgrade.
◆ NOTICE:
(1)The software update disk(17048696 JP-8080 Ver.UP
DISK) consists of a floppy disk(3.5inch) and a list of Check-
sum. Obtain the latest version from the service center.
(2)The program is converted and saved as Standard MIDI
Files(SMF). A sequencer that can play SMF data is
required.(e.g. SB-55, XP-50/60/80)
(3)The file names are as follows.
"vvv" indicates the version number.
For example "102" signifies Version 1.02.
◆ Update procedure
(1)Connect the sequencer MIDI-OUT and the JP-8080 MIDI-
IN terminals with the MIDI cable.
(2)Turn on the power while holding down the two [WRITE]
and [PORTAMENTO ON] buttons.
(3)Press [REC] when the display in Fig.1 appears. You can
quit the version upgrade at this point, by pressing [EXIT].
Check that the display in Fig.2 appears.
(4)Load the file into sequencer. Load in sequence from
vvv_01.MID.
(5)Play the song. Fig.3 appears on the JP-8080 display.
(6)The check sum appears at the end of the song. Check that
it matches the value on the list.
If the value is different, press [EXIT] and repeat steps 5 and
6. (Inquire at your Roland Service center if the value is still
wrong after repeating steps 5 and 6 several times.)
(7)If the value is correct press the [REC] button. Be sure never
to cut off the power while the display in Fig.5 appears.
When loading one file ends, the display in Fig.6 appears.
(8)Load the files one at a time, in sequence from
vvv_02.MIDto vvv_14.MID and repeat steps (5) through
(7) from the procedure.
(9)Once all files have been loaded, the display in Fig.6
appears.
Turn the power off and then to make the factory resetting.
Reload the user data from backup copy.
Error1)If an error message appears during play of SMF, turn
off the power and redo from the beginning.
Error2)In step (7) of this procedure, if "Completed" does not
appear within 40 seconds after pressing [REC] or if
the message "Can't update!" appears, then the
version upgrade is a failure. When this occurs you
must replace the main board.

(20) Press [WRITE], then "DRAM4" is displayed on the LCD.
Delay tones are issued in sequence?
(21) Does the output waveform contain noise?
*If error:
·Check IC21(DSP), IC64(DRAM) and their connections on
the MAIN BOARD.
8. Input Test
Raise the VOLUME LEVEL, the INST/LOWER INPUT LEVEL and
the VOCAL/UPPER INPUT LEVEL to the maximum.
Connect the OUTPUT L and R of JP-8080 to the oscilloscope.
Set the input range of the oscilloscope for 200mV/div.
NOTE:SINE WAVE (i),(ii),(iii) as in the following explanations are as
follows.
Depending on the program version, the value of the SINE WAVE
are different.
Versions earlier than 1.03
SINE WAVE (i) :f=1kHz, LEVEL=100mVpp
SINE WAVE (ii) :f=1kHz, LEVEL=500mVpp
SINE WAVE (iii) :f=1kHz, LEVEL=16mVpp
Version 1.04 or later
SINE WAVE (i) :f=800Hz, LEVEL=75mVpp
SINE WAVE (ii) :f=800Hz, LEVEL=500mVpp
SINE WAVE (iii) :f=1kHz, LEVEL=16mVpp
(1) [fig.13] is shown on the LCD.
Press [WRITE].
[fig.14] is shown on the LCD.
(2) Input the SINE WAVE (i) to the INST/LOWER jack and the
VOCAL/UPPER jack in rear panel.
Two SIG/LIMITER LEDs of INST/LOWER and VOCAL/UPPER
light up green.
The SINE WAVE, the level of which go in two divisions
(400mVpp) of the oscilloscope, is displayed on a screen of the
oscilloscope.
According as you move the rotary volumes of INST/LOWER and
VOCAL/UPPER from the maximum to the minimum, the level of
the sine wave on a screen changes by degrees.
(3) Do Two SIG/LIMITER LEDs of INST/LOWER and
VOCAL/UPPER light up green?
* If error:
·Check IC43, IC44, IC53, IC54, CN3 and CN6 on the MAIN
BOARD.
· Check D84(LED), D85(LED), CN2 and CN3 on the PANEL
BOARD.

(4) Is the sine wave which is proper level displayed on a screen of
the oscilloscope?
According to movement of the rotary volumes of INST/LOWER
and VOCAL/UPPER, does the level of the sine wave on a screen
change by degrees?
* If error:
·Check IC17(DSP), IC32(AD/DA), IC43, IC44, IC46, IC51 and
CN6 on the MAIN BOARD.
· Check CN3 on the PANEL BOARD.
(5) Press [WRITE].
[fig.15] is shown on the LCD.
(6) Input the SINE WAVE (ii) to the INST/LOWER jack and the
VOCAL/UPPER jack in rear panel.
Two SIG/LIMITER LEDs of INST/LOWER and VOCAL/UPPER
light up red.
According as you move the rotary volumes of VOCAL/UPPER
INPUT LEVEL with range from the maximum to the minimum,
the value of "vocal" displayed on the LCD changes with range
from 0 to 127.
(7) Do Two SIG/LIMITER LEDs of INST/LOWER and
VOCAL/UPPER light up red?
* If error:
·Check IC43, IC44, IC53, IC54, Q7, Q9, Q15, Q16, Q17, Q18,
Q23, CN3 and CN6 on the MAIN BOARD.
· Check D84(LED), D85(LED), CN2 and CN3 on the PANEL
BOARD.
(8) According to movement of the rotary volumes of
VOCAL/UPPER, does the value of "vocal" displayed on the LCD
change with range from 0 to 127?
* If error:
·Check IC7(80pin:ESPDAC L), IC17(DSP), IC32(AD/DA),
IC43, IC44, IC46, IC48(VCA), IC51 and CN6 on the MAIN
BOARD.
· Check CN3 on the PANEL BOARD.
(9) Press [WRITE].
[fig.16] is shown on the LCD.
(10) Input the SINE WAVE (iii) to the MIC jack in front panel.
The SIG/LIMITER LED of VOCAL/UPPER lights up red.
The sine wave is displayed on a screen of the oscilloscope.
(11) Does the SIG/LIMITER LED of VOCAL/UPPER light up red?
*If error:
·Check IC44, IC50, IC53, IC54, Q7, Q9, Q15, Q16, Q17,
Q18, Q23, CN3 and CN6 on the MAIN BOARD.
· Check D85(LED), CN2 and CN3 on the PANEL BOARD.
(12) Is the sine wave displayed on a screen of the oscilloscope?
*If error:
·Check IC17(DSP), IC32(AD/DA), IC48(VCA), IC50, IC51
and CN6 on the MAIN BOARD.
· Check CN3 on the PANEL BOARD.
(13) Input Test ended correctly.
Press [SHIFT] or [INC], then Initialize program runs
9. Initialize
(1) [fig.17] is shown on the LCD.
(2) Press [WRITE].
(3) [fig.18] is shown on the LCD.
(4) Press [WRITE] again to exit the test mode, then factory data will
be loaded.
