I program the light scene changes in my DAW, along with the synchronized audio tracks, then dump it into the LP 16. Have not had any issues with timing but I am simply triggering scenes from a MIDI- equipped light controller. No fancy CC messages or anything. My MIDI tracks are various tempos, but I create them in reference/in sync with the audio tracks (most of which were created by MIDI but not all). I don’t know, technically, if the MIDI track “plays” at a standard tempo in the LP-16 but I have not noticed anything not working as expected. As long as everything lines up in the DAW, I have had no issues with everything working together. Don’t know if this helps, I am kind of new to the process as well.
