@Desmond > A few answers for you...
1) Try lowering the buffer (latency) size for tighter response to controller input.
2) The quantize mode affects things like hot cues and loops - DJs asked for individual controls, Pioneer delivered.
3) Can I ask why it matters what the original BPM was?
4) Not all hardware has a SHIFT button, so this behaviour is standardized across all controllers / players.
5) This is a known bug and will be addressed in a future update.
6) You must use a 3rd party software like rekordbuddy to import cue points from other software applications.
7) You probably didn't have the performance analysis mode enabled.
8) Some users are having troubles exporting, others are simply trying to export from performance mode. Try switching first.
9) In the preferences, enable the load lock under Controller > Deck.
