My pioneer djm900 works with OS X el capitan now… just an FYI
Still no sign of 64-Bit drivers for Pioneer DJM-850. 
(I’ve even tried using ASIO4ALL - no luck whatsoever).
AHA! Is this why my DJM 750 won’t work with traktor since I installed Windows 10? The drivers all install fine and the utility shows up when you plug the USB in, but I only get the option for a single stereo line out in traktor’s audio manager. Is this what everyone else is getting?
(I did a full wipe and start again on the HDD btw so it was a fresh OS not an upgrade)
You need this, mate:
Your 750 should work fine(?) then. But only at 32-Bit…
Kapow! Thanks mate I’ll give that a go when I get home (as well as upload that utility that I forgot to push last night)
Been able to work around it a bit by using my audio2 to plug in with but I want 4 channels and the cheeky timecode hack!
A little more detail from Pioneer:

I know it works - but I want 64-bit.
Thanks for all the help guys! Loads more use than Pioneer who, despite me including screenshots clearly showing what I had available, told me to use the ASIO driver which wasn’t in the list in 64 bit mode…
Started in 32 bit mode and everything works like a dream, cheers! 
I’ve had an update, albeit pretty vague (but still reassuring) from Pioneer.
They tell me that 64-Bit drivers for most Pioneer equipment (they did confirm that my 850 will receive new drivers) will definitely be released - but would not provide a timescale for it.
Fair enough, I thought. At least now I know that I can continue (but, I don’t know when) using my 850 with Traktor at 64-Bit.
Still waiting…
The wonders of having a ridiculously strong market position and effective monopoly in clubs.
And a competing DJ software that doesn’t require external ASIO driver, more importantly.
Rekordbox is still a 32bit application, that’s why it works.
I’m still in contact with someone at Pioneer about this, Japan is from what I hear on holidays this week (Golden Week) and so I’ll hopefully hear back next week.
Anything, frankle?
