  Hi Amber,

  if the two items are presented right after one another, you can start with the sketchpad and set its duration to 0 , and then the sampler with the duration set to the variable length of that sound bit, by setting it to sound .

  Hope this helps,

  Eduard

  I can't believe I didn't think of that, I had them the other way around the entire time. Works like a charm! Many thanks, Eduard.

  Hi @amlema,

  You get an error because, as the error message indicates, the information you provide as a duratrion is invalid. A file name is not a duration.

  The solution depends on whether or not you just want to present a sketchpad and sound simultaneously without registering any response (i.e., presentation only), or if you want to register a keyboard response (and if you do, whether you want to register it once the sketchpad's full duration or if the response should interrupt the presentation of the sketchpad.

  If you merely want to control the presentation of stimuli, and register a response only after the full duration of the sound/sketchpad has elapsed, the solution is simple:

  You first present the sketchpad for 0ms, then present the sound, then the keyboard response.

  Best,

  Fabrice.

  Hi @Fab

  Such an easy solution, but it helps so much, thank you! Also, the information on the response registration is really useful - thanks.
