Questions
Does b2b convert a library from Serato or Traktor?
No. b2b works with rekordbox 7 and doesn't convert between DJ apps. Lexicon does, and its conversion is free.
Does b2b generate cue points?
No. Lexicon and Mixed In Key both do.
Does b2b upload my music?
No. Your music files stay in your own cloud storage and on your devices. b2b's servers never receive, store or relay them. The only audio that reaches them is voice you dictate, which is transcribed and discarded.
