Operation
1. Press TRANSMIT CH/MEMORY BULK DUMP
twice.
•
If the PortaSound is already in TRANSMIT CHANNEL
select mode (indicated by an
on the TEMPO/ PA-
RAMETER & VALUE display), press this button only
once.
The TEMPO/PARAMETER & VALUE display will start
to blink, showing that the PortaSound is ready for memory
bulk dump.
2. Press the VALUE + button.
This starts the bulk dump. (The TEMPO/PARAMETER
& VALUE display goes out during transmission.)
Completion of the bulk data dump is indicated by the
display lighting up again. The PortaSound then enters
TRANSMIT CH. select mode.
•
To exit Memory Bulk Dump mode without carrying out
the data dump, press TRANSMIT CH/MEMORY BULK
DUMP
again instead of the VALUE + button.
Reception
The PSS-680 will accept exclusive messages in ANY condition
— no particular setting is necessary. During reception, the
Portasound is totally inoperative, but one indicator dot will
blink to indicate MIDI communication. After a bulk dump,
the RAM contents of the receiving equipment will correspond
to that of the transmitting unit.
If reception of the bulk dump was not successful, the error
message
will appear on the display. In this case, repeat the bulk dump.
Note:
Only that part of the data where the error occurred is reset.
All other system exclusive data is received correctly. In
other words, if an error for instance occurred during
transmission of the digital synthesizer bank 1, only this
data will be reset while all other system exclusive data is
received as intended.
Received Data
With the exception of channel 16, all note ON/OFF data is
used to play the selected voice. Only MIDI note numbers
corresponding to the keyboard’s five octave range are ac-
cepted. Velocity data is NOT accepted in this mode, but can
be received in Sound Source mode 99.
•
As the default setting, all channels 1 to 16 are on for re-
ception. Any channel can be turned on or off with the
RECEIVE CH. FILTER
button (see below).
Channel 16
Note data received on channel 16 functions as if the corre-
sponding drum pads were being hit. See the table on page
32.
Program Change Data
Program change data received on channels 1 to 15 switches
the selected voice, while program changes on channel 16
switch the style.
On channels 1 thru 15, program change values from 00 to
99 select voices from 00 to 99, while values from 100 to 104
access the DIGITAL SYNTHESIZER voice banks 1 to 5.
Values from 105 to 127 select the voices from 00 to 22.
On channel 16, program change values from 00 to 99 select
styles from 00 to 99. Values from 100 to 127 select styles from
00 to 27.
Pitch Bend Change Data
is accepted. The bend range depends on the panel data setting.
Control
Data
Change
Portamento ON/OFF and modulation (vibrato) ON/OFF
and sustain ON/OFF data are received.
System Real Time Messages
Start, Stop and Timing Clock data are accepted. However,
if no external clock data is received, the PortaSound uses
its internal clock.
The external clock can be turned on and off as explained
on p.36, “MIDI RECEIVE CHANNEL FILTER”.
All panel settings remain valid during data reception, only
the tempo control will not work if external clock data is
being received.
