I recently purchased DDJ-RX from the audio shop. First day of using I connected DDJ-RX to my PC was no problem at all, but when I try to connected to my MACbookpro(2007) upgraded to osx 10.11.6 Ei capitan first the audio worked separately (Builtin output,DDRX) then I setting in MIDI setup on laptop to Aggregate device(alike ASIO on PC) so it allowed two devices play simultaneously(I set to aggregate device Built in output and DDJ RX) also set Aggregate device on Rekordbox preferences when I played to song at the same time and I want to line CUE point on my headphone so I going to hit one CUE button below the sound color knob and nothings happened until I hit Master CUE button which is located under sound color option buttons and the audio brought up on my headset. On the other hand, it means that if I play two songs at the same time and I hit Master CUE to line up the CUE points on first song it gonna brings all the songs that playing rather than the one that I push the button. I used speaker connected to my laptop then controller USB connected to laptop
Mac laptop problem conclusion CUE buttons don't work until I push Master CUE. It means it gonna brings all songs that playing
Then..... I get back to connected controller to PC. Now everything works separately on Rekordbox preferences.First I selected Speakers(DDJ-RX) the on audio preferences audio came up on my headset but not on my speakers that connected to PC, but CUE button worked. Second I selected Speakers (Realtek High Definition audio) the audio came up on speakers that connected to my PC but my headset didn't work also CUE buttons. Third I selected ASIO(DDJ-RX) the audio came up on my headset without hitting any CUE or Master CUE buttons also speaker didn't work. My PC's sounds playback I set Speakers Realtek High Definition audio as the default device.
PC problem conclusion audio device works separately even selects ASIO
Thank you.
Your problem on the Mac is that you don't want to create an AGGREGATE device, because then the software isn't outputting properly - you want to create a MULTIPLE-OUTPUT device instead.
The problem on the PC is that there is no output for the headphones when using the built-in output (the Realtek) because it's not an ASIO device and is not configured for multiple output channels from rekordbox, and thus no headphone output.
