Hi Peter, I’ve been using stage tracks to initiate playback of a pre-recorded DMX show for my individual songs. Throughout all of my testing and editing of the files to get them perfectly aligned with the music I did not test the auto play feature. During my first live show I noticed when using auto play that the lights and track were out of sync by about one second or so. I’m using the midi command in which it sends upon play, do you know if there is any difference of when that command sends on an auto play versus a manual play of a track? Or any other reason why they would be aligned during a manual play and not aligned during an auto play?
