Variable onset issues

URL of experiment:

Hello all,

I am trying to present two stimuli:

  • a circle with a fixed onest of 500ms
  • an auditory beep with a variable onset between 300 and 700ms.
    The variable is present in the cond.csv file as SOA.

The issue is that after the first trial, the second one does not appear. I tried waiting, as if it was an error of timing, but the screen remains blank and no errors are shown.
I don’t have more details unfortunately.
Another version with fixed onsets ( works fine.

Thank you for your help!
