Specify transition time when recalling column using OSC message:

The idea is to be able to transition to a column in a specific amount of time when using a external cue manager.

This can be expressed by this articulation:

Transition to [ COLUMN_NAME ] in [ TIME_MS ] milliseconds.

This way, a stage manager could manage a OSC Cue in his qlab for instance that does ' transition to "column_1_blackout" in 10000 ' and 'transition to "column_2" in 5000' and still be able to change this time value without having to interfere in the Millumin composition.

The simplest way to integrate it on message side could be to add a float at the end of the recall message as following.

/millumin/action/launchColumn "column_1" 5000

The time value does not have to change the transition time in the Millumin set, it should only trigger a temporary transition time used once. If no time value is sent in the message, Millumin should fall back to the set specify transition value.

The particular use case where this needed emerged is on a theatre show where Millumin is used to compose the different video scene and a Qlab is used to recall these columns alongside other parameters and timing ajustements.

This way, a Millumin set could have only a empty column (blackout) in the first column and populated column in 2, 3, [...], n .
The qlab could recall non-sequencialy the different column with different timing value and this way skip the redundancy that is needed for some use case (particularly; blackout);

for example :
/millumin/action/launchColumn "column_1_blackout" 0 /*start on column 1, in 0 ms (skipping the transition time) */
/millumin/action/launchColumn "column_2_scene_intro" 5000 /* transition to column 2 in 5000 ms */
/millumin/action/launchColumn "column_3_scene_outro" /* transition time default to what is in the Millumin set because time is not specified in the OSC message */
/millumin/action/launchColumn "column_1_blackout" 10000 /* fade back to 1, in 10000 ms */

Having a playback shuttle would make it easier to scroll through video content fast and call back the video at will instead of having to stop and restart the column. This would help in fast forward and could have reverse play option too. Also it could have more user friendly buttons that would allow for play options at the end of the movie file. (loop, pick up from last played, play once and stop, etc) Speed control could also be in this position so you can do it on the fly and don't have to be in edit mode. You would have to select the column first to be able to achieve this action.
