FYI rekordbox 4.0.5 has been released

still not possible to change the BEAT-GRID proberly!

autoplay no longer works

and i would like an opportunity to enhance the text of the playlist a little bit more.

correction...autoplay works perfectly :-)

I can no longer hear audio through my laptop in either export or performance mode!  

@Bill Haynes Have you tried using the correct audio output in the options menu?
