djm900 bpm readout - does not work as advertised

That may be, but given the usual information available from engineers, I'd say this is fantastic.

There are plenty of people who are quick to complain, and some even offer a solution, but not all solutions are the best option to implement - quite often a work-around is really the best way.

LOL,,, true

There should be a good fix ore update for this problem. A 'work-around' is not the answer Pioneer djm-900 users are looking for.

We payed a lot of money for this stuff, and when Pioneer can not meet the specs of this mixer this is a bad thing! 

I think it's quite simple and obvious...

If the link is connected, the mixer is looking for the BPM signal there rather than the audio because it's going to be more precise coming from a rekordbox beatgrid.

BriChi has it the right way -- simply connect non-rekordbox audio via other channels, for example the CDJ and link to CH1/2 and Serato's output to 3/4.  I don't see a problem with doing that.

When connecting my dvi 1000 to the djm 900 I have this problem from non detecting bpm

I'm going to assume you mean DVJ; which terminal on the channel input are you using for that connection?

Yes sorry dvj 1000

I used al connections for it

Are you connected to the DIGITAL, LINE or CDJ input on the mixer?

Ive tried it with line and digital. Both got the non detecting bpm on the djm 900

What channel was the effects knob set to?

What do you think... the one the dvj was on

You say that like I'm a mind reader!  :D

What was the tempo of the music playing and the style?

Most of al 130 and 100, 110 

And the style?

house, moombahton, dancehall, hiphop

The last 3 are most likely to have irregular rhythms (non-4/4) and thus cause the BPM to read inaccurately.

its the same music I play on a djm 800 sometimes, and the djm 800 will show the bpm accurate!

So the problem is in the djm 900. So please go look for a answer with your people at Pioneer.

This is going nowhere!!!

hey michel, as per Pioneer from another post

FYI: The engineers are working on improving the BPM readout.  We will post any updates we receive.

which is a good sign because I used all serato last night, no RB LINK and the bpm is all over the place, i finally gave up and used the tap button, i was mixing mostly top40, club and EDM, and the bpm would shoot to 165, then down to 132 but then the beat marker would be like 3 steps away from center, I constantly had to be on the "auto bpm" for it to work right on "auot", the 800 I never had this issue so no one from Pioneer an say it's the same they used across all mixers, obviously something had changed and they tried to "improve" the accuracy

See my previous statement from the engineers.

We don't want no statement, we want a update!

Pulse, you asked earlier if he was using digital, line or ...  Does that matter for the BPM reading?  I just switched to digital cables so just wondering.  

Thanks

@untitled > See earlier post re: statement from engineers regarding the LINK.

oh, thanks and sorry :D

No worries - low signal-to-noise ratio in some threads.  ;)

tried out new firmware and the bpm detection is ALOT better.. the particular issue I noted above seems to be gone.  I tried at least one of the problematic tracks and it kept a stable bpm when the drums went out.  Good job pioneer

same here, did a very brief test and it seems more stable now, 

HUGE miss understanding with the pioneer pr with this mixer - somewhat miss leading i think!

As im just about to buy a 900 i thought id do some research... quite often videos and reviews detail beat accurate / quantised effects on the mixer with the pioneer pro link with cdjs or rekordbox... but realistically how many djs actually take their laptop and network switch with them to dj? They dont readily tell you this bit.. leaving people thinking that they can pro link two cdjs to this mixer, when in fact you do need other bits to make it work!

The BIG issue here is that this mixer has only one pro link, so you cant plug two pro linked cdjs into it - you either need an external ethernet switch or use the mixer to 'listen'. Now if you use the latter 'listen' mode, this mixer isnt quite quantized with the cdj any more so than the 700, 800 or 850.. unless pio have spent a bit more time on the beat detection in the 900?

Speaking of which, it would seem since the new fw has been out beat detection is a little better, but still on quiet parts of the track bpm might drop off... making the pro link a better solution, as you know when the beat drops back in any effects your playing with will be on time.

On another post Pulse did mention that the 900 didnt have enough room for another ethernet port (somewhat shocked by that comment).. but i think this is something pio should really look into for future mixers... on a side note, i personally think all pro link products should have two ports, which will then allow for daisy chaining upto 4 cdjs and mixer.  ie cdj + cdj > mixer < cdj + cdj with only two ethernet cables going into the mixer as the outter two would loop through the inner two cdjs.

Alternatively could the bpm data be sent over the digital link - now that would be a top idea!  I bet there's a huge amount of bandwidth in that cable that could be tapped into to enable this feature! 

An opportunity to send other info over the digital link will negate the need for the pro link when out on the road... when not using a laptop, network switch and a combination of djm & pro linked cdj's :)  And yes i realise the ability to share usb drives and whatever also gets sent over the pro link... but in this scenario id much rather use a usb device per cdj than have to use a network switch.

Any chance that could be sent back to the development team at pioneer - eh pulse.. what do you think... sending bpm data over the digital audio link?

As far as I know, linear PCM doesn't allow for non-audio data on the digital stream.
