Quantize efx with both djm900 and 2000

It uses the beat grid I believe

Yes the CDJs output the beatgrid information from RekordBox analysed tracks.  The DJM-900/2000 reads this data and uses it to Quantize the FX.

So unfortunately, if you're using Serato be it HID or control disc, you won't be able to use Pioneer's quantized FX.

The quantize is from the beat grid.

:(

Don't get all frowny, here's the complex issue...

The quantized beatgrid information is stored on the track.  When playing from a CDJ or Rekordbox, that beatgrid info is sent over the LINK to the mixer which can then quantize the effects.

Even if Serato had compatible quantized beatgrid data, they'd be sending it down the USB, not over the LINK.  Either they'd need to have a way to send data down the LINK directly (which is unlikely because then Pioneer would be making their source open to an outside company) or Pioneer would have to find a way to bridge the quanitze data from a USB input to the CDJ over to the LINK to send it to the mixer ... and even that may run into latency issues.

Out of interest, Pulse, are you sure that RekordBox transmits the Quantize information to the DJM?  Is it a case of RekordBox transmitting track data and quantize information to the CDJ, which then sends out the quantize information specifically for the DJM to pick up?

I ask this because, for example, when you slow down the tempo on the CDJ whilst using a quantized Trans effect, how else would the DJM know that the track is slowing down in order to adjust the effect timing?  RekordBox isn't aware of the tempo being applied by the CDJ (or, it has no reason to need to know), so the CDJ must be the entity transmitting the quantize info to the DJM.

Unless the CDJ transmits the info to RekordBox, which send it out to the mixer - but that would be silly, surely?  Hmm, of course though, if it were RekordBox transmitting the info, then I guess all the CDJ would have to do is transmit the tempo info to the mixer - still weird though because the CDJ has the quantize info anyway in order to use the beatgrid!

@ Cody L:  What CD decks do the club use?  If they have a DJM-2000, I'd expect them to be kitted out with CDJ-2000s or 900s.  So you could just use RekordBox in that case anyway? :)

@Mark90 > Sorry, overly simplified the steps, but yes, it still goes over the LINK.

So it's not:  RB >> Everything

More like:  RB >> CDJ >> DJM

So... if you, say, only had a DJM-2000, you couldn't expect RB to provide the DJM with quantize information if you made use of the Pro Link + Cue Link feature, in order to make RB transmit the info and 'fool' the DJM into receiving and using the info?

Correct; it goes from RB to the CDJ then to the mixer; as if you apply any pitch changes, the mixer needs to know!

No - the Cue Link doesn't provide beatgrid data to the FX section.

For what it's worth, this little insight along with experience of my home DJM/CDJ 2000 setup linked with RB, my recent foray into using an SL2 and also with HID... RekordBox is, by far, my preferred option.  I don't need the extra DVS faff involved with software like Serato or Traktor - the CDJs are my tools.  The Quantized beatgrid + fx, full waveforms, instantaneous nature of Link and decimal BPM accurracy all come together to form the complete package.  It's not obvious until you've experimented with all of the above methods.

Unfortunately, the prerequisite is CDJ-2000s (or 900s) wherever you go.  Which, unfortunately, is still a big ask, mainly due to the ££££'s :(

so I have a question then, Doe the quantize actually have to be enabled on the cdj2000's for the quantize to work on the djm900? I would think if it's just reading the beat grid, then I can leave quantize off on my 2000's but still take advantage of the quantize bpm staying with my tracks on the djm900 so i don't have to worry about the auto bpm, 

I believe it does.

@ Mark90> I couldn't agree with you more, when I got my CDJ/DJM 2000's I downloaded the demo of the latest Traktor and after a week or so I felt that it was so unnecessary because RB does everything I need it to, everything else the mixer and CDJ's do.
