Dual Task with Direct RT?

Is it possible to do dual task with DirectRT? That is, I want to set it up so
that for each trial both a sound (tone) and picture are shown (this I know how to do) and then both a vocal response and button press are recorded, in any order (this I'm not sure how to do). I tried using the "multple responses" with an rt1.txt file like:
#1,44,53
#2,aud

... And then in the .csv file I call it as rt1:44, aud
(for example)...
But it doesn't work - it only seems to only be recording the button presses and ignoring the vocal responses. Note: vocal responses by themsleves work on my set-up so that's not the problem.

Anyone know?

Thanks,
Josh

I think you can specify a key code when specifying a voicert so that a keypress and a voice response may be taken. See
