Eprime triggers to EEG out of sync

[aldelfino]

Hi Paul,

maybe I haven't stated my problem clearly enough. For now, I decided to 
change the script. I eliminated the response object and used a Sound object 
instead of a Slide object. My biggest issue is on how to play a certain 
audio file and make an associated trigger to be sent to EEG a few 
milisseconds after the onset of the same audio file. So far, I'm able to 
send the triggers, but the 'sleep' function delays both audio execution and 
trigger signal. Is it possible to set up the sleep function only for the 
trigger? Please find below an updated version of the inline script:

Dim StimTrigger as Integer
Dim StimDelay as Integer
StimTrigger = c. GetAttrib ("Trigger")  'condition-associated trigger
StimDelay = c. GetAttrib ("Delay")  'delay in milisseconds a trigger must 
be sent to after the onset of the audio file
SoundOut1.OnsetSignalEnabled = True
SoundOut1.OnsetSignalPort = &H378
SoundOut1.OnsetSignalData = StimTrigger
sleep StimDelay (?)


Thanks,

Alexandre.
