Collecting Single or multiple response

[smacats]

Hi,
In my experiment I am presenting some trials with dual tasks, where one task is visual and the other auditory. The auditory task has fairly continuous keyboard pressing (every sec), and takes place until the a different key is press (signaling the end of the visual task). I want to record RT data for both key presses (with a "full' time maxing on the auditory task and have skipping options with the visual one). Is there any way to collect data for both tasks and key presses? I would need the program to allow the option of either one (for the auditory task) or two (for both the auditory & visual tasks) key presses.
Any suggestions?
Thanks.
