Hi everybody, i'm trying to sync Advanced scene switcher to a music source, but it loses sync, i believe i figured out what causes the loss. It's "check switch conditions every..." Is there any chance to keep the sync with song? (i'm talking about the sync of the switch).
Are you trying to sync it to the beat, using the ms scan interval? That's really hard for any application. Not impossible, but good luck.
Are you keeping the switch interval "reasonable" while using an audio volume trigger to try and catch the beats? That's also hard because not all music has a reliable peak on every beat, and a "reasonable" interval is still slower than you really need to make that work. 120BPM, which seems like a reasonably exciting tempo that you might want to coordinate something to, is 2 beats per second, or 500ms between beats. But you want to scan significantly faster than that, so you can switch ON the beat instead of slightly off. (The general rule of thumb for direct unfiltered control is at least 10x faster, which is much faster than Nyquist as understood from the DSP world.)
The best option might be to make a video in a separate editor, do all of the tight timing in there, and then just play the video. Or if it must be live, have someone listen and push a hotkey for every switch. Adv. SS is then reduced to picking the next thing so that it's ready for the next switch, but not actually switching yet. That doesn't require nearly as fast scanning as it does to time the switch just right.
