You could possibly try putting those CC123.0@x commands in the global Song Load settings then each song should start with a 'blank slate'.
I was trying this with QLC+ at the end of last year and I noticed I was sending a lot of CC123.0 commands during the songs, desperately trying to zero everything.
Bear in mind that some DMX lights might persist if your fixtures are set to HTP rather than LTP. I learned that the hard way. Just sending 'all notes off' does not turn all the lights off in my experience.
Remember also that some gear (Boss loop station, I'm looking at you) requires that you send note-on/note-off combos. My lyrics files are full of stuff like CC11.127@13, CC 11.0@13 to start it then CC11.127@13, CC 11.0@13, CC12.127@13, CC 12.0@13 to stop it again... P in the A...
