07 (Fire):
Macros can be fired by this command. It needs to be followed by a single octet specifying the macro number.
Macro number 1 is hex number 01. Hex number FF is macro number 255.
Example: Triggering macro number 24 (All Devices and All Format setting):
F0 7F Device ID 02 Command Format Command Data F7
F0 7F 7F 02 7F 07 18 F7
0B (Go_Off):
Executors can be turned off using the 0B command. A cue number needs to be transmitted - cue 0 can be used.
Example: Send an Off command to executor 9 on page 5 (All Devices, All Format, and Exec.Page setting):
F0 7F Device ID 02 Command Format Command Data F7
F0 7F 7F 02 7F 0B 30 2E 30 30 30 00 39 2E 35 F7
MIDI via Ethernet
MSC can sent using Ethernet. It is transmitted as a UDP message.
The MSC message is the same as described above, but the MSC message needs a header for the date to be
accepted by the dot2.
The header is separated into two parts. The first is identifying the message as a dot2 MSC message: 47 4D 41 00
4D 53 43 00 - it translates to GMA MSC.
The second part is four octets describing the length of the message - including the header. It is written as little
endian byte format (least significant first).
This is calculated by counting the number of octets and then convert the decimal number into hex. Usually we
only needs the first octet (it allows for messages up to 255 octets) although all four needs to be sent.
Examples:
Send a go command to cue 35. The MSC message is: F0 7F 7F 02 7F 01 33 35 2E 30 30 30 F7.
This is 13 octets. The header is always 12 octets. So the combined length is 25 octets. Decimal 25 is 18 in hex.
The entire message is:
