2.4 PROGRAM CHANGE (Cn)
When the SPX2000 receives this message, it will recall the effect specified
by the content of the program change table (page 22).
• Reception conditions
This message is received if the following two conditions are satisfied.
1) The “MIDI RECEIVE” setting (page 23) is “PGM CHANGE = ON”.
2) The channel on which the MIDI message is transmitted matches the
SPX2000’s MIDI channel, or the SPX2000’s MIDI channel is set to
OMNI.

2.5 TIMING CLOCK (F8)
This message is used for tempo synchronization of the effect. Twenty-
four of these messages are received per quarter note.
• Reception conditions
This message is received if the “TEMPO SOURCE” setting (page 23) is
set to a tempo synchronization source of “MIDI.”

2.6 ACTIVE SENSING (FE)
Once the SPX2000 has received this message, failure to receive a message
of any kind for an interval longer than 400 ms will cause it to initialize
MIDI communication settings such as running status.

2.8.1 BULK DUMP/BULK DUMP REQUEST
Bulk Dump messages are used to bulk dump SPX2000 data to a con-
nected MIDI device (see page 23) , or to receive data from a connected
MIDI device to overwrite internal settings of the SPX2000.
Bulk Dump Request messages request a bulk dump of data from the
SPX2000.
• Reception conditions
This message is received if the following two conditions are satisfied.
1) The “MIDI RECEIVE” setting (page 23) is “SYSEX BLKDMP = ON”.
2) The device number within the MIDI message matches the
SPX2000’s MIDI channel, or the SPX2000’s MIDI channel is set to
OMNI.
• Transmission conditions
This message is transmitted when either of the following conditions
are met.
• The “BULK OUT (ALL)” function is executed to perform a bulk
dump.
• A Bulk Dump Request message is received.
• Data conversion
The data portion is handled by converting seven words of 8-bit data
into eight words of 7-bit data.
[Converting actual data into bulk data]
d[0~6]: Actual data
b[0~7]: Bulk data
b[0] = 0;
for( I=0; I<7; I++){
if( d[I]&0x80){
b[0] |= 1<<(6-I);
}
b[I+1] = d[I]&0x7F;
}
[Restoring bulk data into actual data]
d[0~6]: Actual data
b[0~7]: Bulk data
for( I=0; I<7; I++){
b[0] <<= 1;
d[I] = b[I+1]+(0x80&b[0]);
}
