I am using rekordbox one week now with pioneer ddj - RR controller. When i test and try to learn the program i had a basic problem with sound. At first i was think that is my pc fault but i change pioneer buffer in 1024 from 256 and now i have not noise at all after 3-4 minutes as i had before. But i went to my job i connect my gear and i tried to play. After some minutes i just trying to volume up my next song and the song was stucking for 2 seconds. I said its ok... Quo fter 10 minutes when i trird to touch a volume fader in the air the song was trimming again. So i stop make mixing all the time and i was waiting the song to end and load next. I am sure that its not pc fault. I have an asus laptop i7 2.8 ghz 6 g ram and when i am playing the cpu is in usagebby 12% ram at 39% and hdd at 2 % ifvanyone has the same problem could advice me what to change in preferences. What about my suggestion: i was using traktor pro for 5 years and now change to rekordbox, i start change my mind and iblike rekordbox but pioneerbhave lot of work to makr the program better... I suggest put a search bar not only in all collection but in all folders or playlist to anage better our searching when we play on air...
