Fade cue Effect tab

[Kalman Tarr]

Hi,

I am using an effect (Low pass filter) to be affected to selected and running Audio cue. 

When the audio is running I trigger the script below

.

tell application id "com.figure53.QLab.4" to tell front workspace
    set theAudio to last item of (cues whose running is true and q type is "audio")
    set cue target of cue "fout" to theAudio
    set cue target of cue "fin" to theAudio
end tell

It sets two different fade cue target according to running audio. It is good I think.

But when I set the target to FadeCue, on effects tab the "enabled" parameter switch off. Is this natural thing?

I don't understand why. I would like to switch it back but I don't find any parameter in Applescript  Fade cue list.

I tried to present the details of my problem in above enclosed picts.

Any suggestions pls...

Best

Kalman
