Hello,

I am trying to run a behavioral experiment using DirectRT. Is it possible to record the reaction times (and correctness) of multiple keypresses within a single file? I will be playing roughly 5 musical excerpts and subjects will have to press a button when the hear a mistuning in the violin line and when they hear a mistuning in the clarinet line. Each line will have 6 probes within each sample and I need to record the RT's for each keypress even they are all within one sound file.

I have read the user manual and done the tutorials with the sample files but am unclear about how to go about coding this experiment. Any help would be much appreciated. Thank you!
