The second of the two numbers for the faders are the page number. This is a little different page 1 is hex number
01and page 2 is hex 02 and so on.
So executor 1 on page 1 is 00 01.
Calculating the position in hex numbers is a bit more tricky. The faders position is defined by a coarse and fine
value. The scale for both values is 128 steps (most MIDI is in 128 steps). The fine value is transmitted first
followed by the coarse value.
The desired fader position (in decimal) need to be multiplied by 1.28. The resulting integer is the coarse value.
The remainder (everything on the right side of the separator) should be multiplied by 128 to get the fine value.
The two decimal numbers then needs to be converted to hex.
Example:
The fader 3 on page 2 needs to be moved to 45%. First convert the position.
1. Multiply 45 by 1.28 = 57.6
2. Coarse value is 57.
3. Multiply 0.6 by 128 = 76.8
4. Fine value is 76.
5. Convert decimal 57 to hex = 39.
6. Convert decimal 76 to hex = 4C.
7. Fine is transmitted before coarse so the position is: 4C 39
The MSC message is (All Devices and All Format setting):
F0 7F Device ID 02 Command Format Command Data
F0 7F 7F
A fade time can be added after the fader and position data. The time format explained in the 04 command is
used.
Example: Moving fader 15 on page 1 to 100% in 5 seconds (All Devices and All Format setting):
F0 7F Device ID 02 Command Format Command Data
F0 7F 7F
The console only transmit the position of some faders - executors with sequences and all the green colored
special masters (for the selected executor), but it accepts positions for all faders that have something assigned.
