CDJ 900 firmware 4.10

@ Chris, I find it hard to believe you don't here any improvement after upgrading to firmware 4.10, as many users above and myself, really did notice the difference in MT qualiy (less jitter). Don't get me wrong: I'm not saying it's perfect and as far as I can recall, my (sold) pair of CDJ-1000 MK3's performed better on MT.

At least for me, since 4.10 I can again use the MT function for beatmixing with the CDJ-900, although I rarely speed a track down or up by more than 5%. And yes, I think Pioneer should further improve the MT on the CDJ-900/2000.

@Chris > What did you update from / to? Was it 4.10?

@ DeAl - After using the new firmware for a week I can report that the MT is more stable the closer you get to 0%. At +6% its not that bad and I would probably use it if out gigging but beyond that (especially at +10 and above) its terrible. Your right what you said about the MT on the 1000's it was definitely much more stable and could be left on all the time without problems.

@ Gavin - I updated from 4.05 to 4.10.

 I notice the problem more when really speeding vocal house tracks to +10 and above

Which begs the question, why are you pitching vocal house +10% or more?  House is usually in the 120-130 range, adding 10% to that is 132-143...

@ Pulse - I tend to play at 132bpm and I have some tracks that are around 124bpm @ 0%. I could have the bpm lower and not use MT but surely thats the whole point of that facility isn't it?? 

@Chris > It's not a strict rule that house is in that range, but when you're pitching tracks to +10% with MT engaged, artefacting is to be expected.  If you want to avoid it, you'd be better off time-stretching your tracks in a DAW.

To put it more frankly than Pulse, MT sounds terrible when used to the extremes. This has always been the case in CDJs. Digital artifacts. The general consensus in the community has been that +/- 6% with MT on is OK. Personally I turn it off at more than +/- 3% but that's just my preference. 

@ Chris - Don't expect to mix such varied bpms with MT on without sound degradation.Your choices are either putting up with the sound quality. Turning MT off. Pick tracks with bpm closer to the current track (duh). Or warp tracks before hand.

Thanks for the input guys. I didn't think that I was trying to use MT to the extremes but if keeping below +6 is the general view of the other users then I will try to work within that. Like I said in the earlier post I find 4.10 a damn sight better than 4.05 so at least things are progressing in the right direction.

I just upgraded my CDJ900's to 4.10 and there is definitely an improvement - in one of my other mixes I was throwing in a few random tracks, some up to 10bpm different - it sounded terrible with MT enabled in the previous firmware (4.04/4.05) but fine with MT disabled... now with 4.10 it is definitely more bearable, still not perfect, but definitely better than it was before :)

@drclaw > Thanks for your feedback.

i just purchased pioneer cdj 900 and i have updated them....but im noticing that the tracks are having a hard time staying in sync even when the tempo is matched? What can i do to fix this???? Im using a usb....Also everytime i load a track into one of my cdj it starts playing the song right away before i even press play how can i change this?? Thanks!

turn on auto cue by holding down the time mode/auto cue button for 2 seconds

@Shandon > Chances are you have analysed non-constant tracks with normal analysis mode or constant-beat tracks in dynamic mode.
