Hi Pat, congrats on getting an RB-DMX1!
I'm sorry but I don't understand what you mean in the first issue -- you shouldn't need to remove the songs from the collection. Simply analyse them with the PHRASE enabled and they will automatically assign macros to the songs. Can you elaborate on what's happening?
Fixtures are added weekly, but that doesn't necessarily mean they'll be available or fully functional within rekordbox lighting -- currently only pars, bars, movers, strobes, and pinspots are supported. FX, lasers, foggers, scanners, etc. are not yet supported, some (like FX) may work, but in a very rudimentary fashion. Unfortunately those scanners are not a supported fixture type (yet), even though they are similar to a moving-head.
