Timecode + Scene time = Out of sync

[martie]

Hi,
I'm new here but little experienced with Freestyler. Recently I found a problem with synching
I'm making a very specific show for a music track. I use one MARTIN ACROBAT.
The options I setup:
- Timecode (Elapsed)
- I make one sequence in the Cue list without any fades (only snap or off setting)
- Play it in the cue list.

The music track need first 48 seconds of a specific gobo and then 10 seconds nothing and after that 4 seconds of a specific gobo and then it should turn off.
I tried the following:
- Make a sequence with one step with a scene time of 48000 with specific gobo and max intensity.
- Make in the same sequence another step with a scenetime of 10000 with lamp off
- Make in the same sequence another step with a scenetime of 4000 with the same specific gobo and max intensity.
- Make in the same sequence another step of 500 with lamp off.
- I saved it and inserted it (without a loop) in the CUE.

I start the music track and the gobo intermediately works, only after 48000ms it should stop. However it stops at about 54seconds. The speed is 100%.

So how come my scene time of 480000ms / 48 seconds is not exactly correct and the Martin turns off at 54 seconds?

Martie.
