I'm making a study using music in Superlab 4.0, and I'm trying to create a visual stimulus that will act as a metronome, blinking along with a given song. For example, in a given trial, I might want the stimulus, which is a picture file, to be displayed for 100 ms, then go away for 400 ms, then repeat until the song ends (the length of each song varies trial to trial).
Is there any way I can make a loop like this? I can't find anything that would allow me to present it multiple times.
Thanks in advance!
