Data is lost when you write to the preset library.
The unique header (Model ID) identifies whether the device is a
M7CL.
To calculate the check sum, add the bytes starting with the byte
after BYTE COUNT (LOW) and ending with the byte before CHECK
SUM, take the binary complement, and set bit 7 to 0.
CHECK SUM = (-sum)&0x7F
Bulk Dumps can be received at any time, and can be transmitted
at any time when a Bulk Dump Request is received.
A Bulk Dump is transmitted on the [Rx CH] channel in response to
a Bulk Dump Request.
In the data portion, seven words of 8-bit data are converted into
eight words of 7-bit data.
[Conversion from actual data to 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;
}
[Recovery from bulk data to 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]);
}
3.2 PARAMETER CHANGE
Reception
This message is echoed if [Parameter change ECHO] is ON.
This message is received if [Parameter change RX] is ON and [Rx
CH] matches the Device number included in the SUB STATUS.
When a parameter change is received, the specified parameter
will be controlled. When a parameter request is received, the current
value of the specified parameter will be transmitted as a parameter
change with its Device Number as the [Rx CH].
Transmission
If [Parameter change TX] is ON, and you edit a parameter for which
control change transmission has not been enabled, a parameter
change will be transmitted with the [Tx CH] as its device number.
In response to a parameter request, a parameter change will be
transmitted with [Rx CH] as its device number.

4.1.1 Format (Parameter change)
Receive
Data will be received when [Parameter change Rx] is on and the
Device number of both [Rx CH] and SUB STATUS are matched.
The data will be echoed when [Parameter change ECHO] is on.
The corresponding parameter will be changed immediately the data
is received.
Transmission
Data will be transmitted with the [Device Number] in [Tx CH] when
[Parameter change Tx] is on and the parameter is not registered
on the [control change assign table].
