You simply set up a <trial> with a short /timeout or /trialduration, while simultaneously setting the <sound> (for WAV) or <video> (for any other audio formats) element's /playthrough attribute to 'true'. You then /branch to another <trial> that displays your message and accepts the spacebar as response:
<block someblock>
/ trials = [1-2=soundtrial]
</block>
<trial soundtrial>
/ stimulusframes = [1=somesound]
/ validresponse = (0)
/ trialduration = 50
/ branch = [trial.messagetrial]
</trial>
<video somesound>
/ items = ("30seconds.mp3", "60seconds.mp3")
/ playthrough = true
</video>
<trial messagetrial>
/ stimulusframes = [1=sometext]
/ validresponse = (57)
</trial>
<text sometext>
/ items = ("Your message here")
</text>
The audio will be played to completion (regardless of how long it is). Then the sound trial will automatically end and bring up the message trial.
