About Scene Timing - Martin MiniMAC Maestro User Manual

A B O U T S C E N E T I M I N G
Each scene has a dynamic part -
the fade - during which effects
move to the scene's programmed
positions, and a static part - the
wa i t - w h e r e e ff e c t s d o n o t
change.
The duration of the fade and wait
is programmed individually for
each scene. The fade time may be
0 - 120 seconds; the wait time
may be 0 - 600 seconds. The total
time it takes a scene to execute is
the sum of the fade and wait
times.
When operating multiple fixtures, the wait time is determined by a master fixture.
Each fixture fades and waits at the its own rate and then remains in the "wait state"
until receiving a start scene xx command from the master fixture.
When programming in Master/Slave situations, keep in mind the following:
• Every fixture can have up to 20 on-board scenes with individual fade & wait times.
• Scenes are numbered from 0 to 19.
• A scene contains a fade-section, followed by a wait-section.
• When running "synchronous triggering" the master issues commands to the slave
fixtures to "go to scene xx", where xx is the scene number that master will execute
next.
• If a slave has fewer scenes than the master directs it to run, it will derive which
scene to go to by dividing the number of the scene it has been commanded to go to
(scene 5, for example) by the total number of scenes that the slave fixture has (4, for
example) in whole numbers (no decimal places). In this example 5 divided by 4
results in 1, with 1 remainder. This remainder will be the number of the scene that
the slave fixture starts - scene 1. Generally though, when a Slave fixture reaches its
own last scene before the Master fixture, a "go to scene x" message will result in the
first scene being played.
• If a slave has more scenes than the master calls, the last scenes in the slave will
never be executed.
• A slave fixture will not listen for the next message from the master fixture before it
has finished its current scene. This may result in skipping a slave scene if slave has
a longer scene time than master. Note that in the following example that the Slave
