Eprime triggers to EEG out of sync

[Paul Groot]

Hi Alexandre

I would advise to use the new EP2-Pro *Task Events* mechanism here:

No need to do such inline programming anymore with Task Events...

>
> 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 (?)
