assign a preloaded soundbuffer to the soundbuffer of a SoundOut object?

[Emiliano Díez]

Thanks David

I am using EP2.0.10.242. Your solution sure will work for the "video/sound 
part" of the problem. But also I have to record reaction time to the sounds 
and to know if that reaction times occur before or after the end each 
sound. That is the point where I needed the sound object. But think I have 
found a solution using a Do While-Loop and a wait object of 0 duration just 
after the inline that plays the cached sound. Also, I prefer not to have 
several objects for the same funcionality if not totally necessary (in this 
case I prefer messy inline code).

Thanks again for your suggestion
