In a previous post ( it was mentioned that it might be possible in MediaLab 2012 and 2014 to have the probes.csv file present actual sound files instead of simply generating tones.

What I need is for the probes.csv to create a white noise probe at specific points (think STRTs, but instead of a clean tone it has to be white noise), and when the white noise probe is emitted, I need a TTL signal to be sent to my Biopac MP150 so that AcqKnowledge can put an event marker in.

I have the probes.csv file already built and it works fine with the standard tone(X,Y,Z) notation. So, I need to know how to get the file to simultaneously play a white noise .wav file and send a specific TTL signal out.

Is this possible?
