Marquee can respond to other consoles or show control devices using the MIDI Show Control (MSC) protocol. There is a Cue List Property that can specify that Marquee outputs MSC on a particular cue list so that it can control other devices. The connection is made using a standard 5-Pin DIN connector on the optional MIDI / SMPTE Interface.
The MSC format is as follows:
F0 7F <device_ID> 02 <command_format> <command> <data> F7
Note:
Marquee is <device_ID> 0 by default
No more than one command can be transmitted in a Sysex (System Exclusive command).
The total number of bytes in a Show Control message should not exceed 24.
Sysex's must always be closed with an F7H as soon as all currently prepared information has been transmitted.
Q_number and Q_list are expressed as ASCII numbers 0-9 (encoded as 30H-39H) with the ASCII decimal point character (2EH) used to delineate subsections. Marquee uses a 'best-match' method to determine the cue list name based on the label used in Cue List Properties. For example, a cue list named "01-Main" would be referenced by MSC as Cue List 1 or 31H.
Example:
On Device 0 a GO on Cue 235.6 in cue list 36.6 would be represented by the hex data:
F0 7F 00 02 01 01 32 33 35 2E 36 00 33 36 2E 36 F7
The MSC commands supported by Marquee include:
Starts a transition or fade to a cue. Transition time is determined by the cue in the Marquee. If no Cue Number is specified, the next cue in numerical sequence GOes. If a Cue Number is specified, that cue GOes. Transitions "run" until complete. If the Controller wishes to define the transition time, TIMED_GO (see below) should be sent.
01 GO
<Q_Number> optional; required if Q_list is sent
00 delimiter
<Q_list> optional; Marquee uses closest match on Cue List name (if omitted, Marquee will use A/B)
Note:
If a GOTO Cue 0 is sent, Marquee will Release the cue list.
Halts currently running transition(s) on the active Cue List.
02 STOP
<Q_number> optional; required if Q_list is sent
00 delimiter
<Q_list> optional; Marquee uses closest match on Cue List name (if omitted, Marquee will use A/B)
Causes STOPped transition(s) to continue running. If no Cue Number is specified, the current cue list will continue if Halted.
03 RESUME
<Q_number> optional; required if Q_list is sent
00 delimiter
<Q_list> optional; Marquee uses closest match on Cue List name (if omitted, Marquee will use A/B)
Starts a timed transition or fade to a cue. If no Cue Number is specified, the next cue in numerical sequence GOes. If a Cue Number is specified, that cue GOes. Transitions "run" until complete. Time is Standard Time Specification with subframes (type {ff}), providing anything from "instant" to 24 hour transitions.
04 TIMED_GO
hr mn sc fr ff Standard Time Specification
<Q_number> optional; required if Q_list is sent
00 delimiter
<Q_list> optional; Marquee uses closest match on Cue List name (if omitted, Marquee will use A/B)
Is equivalent to releasing all cue lists.
0A RESET
