Right now the console will not accept any time specified in the Frame and Fraction sections. But it transmit values
below a second in the Frame section. The console divides the second into 24 frames. So 0.5 seconds is 12 Frames
and the received hex number would be
0C
.
Example:
Goto cue 75 with the fade time of 20 seconds (

06 (Set):
The set command is used to move a fader to specific position. The 06 command is followed by two hex octets that
indicates the fader and then two more octets that dictates the position.
The first of the two numbers for the fader is the fader number (on a page). The fader number 1 is hex number
00
,
the second is
01
and so on. Remember that this is a hex number so fader 16 have hex number
0F
and decimal 17 is
hex
10
.
The second of the two numbers for the faders are the page number. This is a little different page 1 is hex number
01
and 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
