A couple things I don't like:
When using the touch pads for the 'beat jump' function, the song gets off time. For example, if I skip forward 16 bars, the needle will be slightly off of the 16th bar. The video I posted shows this.
Also, on occasion, the loop function seems to be off time when it is supposedly 'quantized'.
Ocassionally when I load a song to a deck, the waveform will not show up on the display. This makes it difficult to mix on solely visuals which is my preferred method of mixing. I've also noticed this problem on the XDJ RX. I'm not sure if this is a rekordbox issue or a hardware issue.
