Audio File Cue Triggered via “DMX In” Skips First Few Milliseconds on First Use

Post by BeigheyMW » Thu Aug 07, 2025 8:31 am

Today was my first try at triggering audio cues via "DMX In". It was easy to setup and worked (sort of) on first attempt. But I couldn’t hear the first few milliseconds of the audio cue on first playback. The remainder was heard fine. I immediately triggered the cue a second time and the full audio cue played that time (and subsequent immediate plays). Letting everything sit for a minute put things back into the same issue – first playback missed half the first work but subsequent immediate playbacks were fine. And oddly enough, everything seems to work fine if I use the Go button rather than DMX In.

Anyone have any thoughts on what I’m doing wrong? Assuming it had something to do with preloading/caching I messed with the Run Time Settings / Run Mode but none of those drop down options fixed the problem.

The show file for testing only has two cues in it – each no more than 5-10 seconds long (both .WAV format – seemingly a very light processing load). The lighting rig snaps (not fades) the designated channel from 0 to 255 for triggering and resets back to 0 in 0 seconds when I release the Flash button. The two cues are set for Manual activation with MIDI/DMX Cue of 0 in the first and 1 in the second. As far as I know the laptop has a solid state hard drive if that matters.

TIA,
Mark

This is probably due to settings outside SCS. Try the recommendations in FAQ 11 on our FAQ page.
