DJM 2000 midi controls Traktor Pro

Hello Pioneer Peoples,

Using DJM 2000 as a control surface for Traktor Pro 2.5 for DJ and Remix Studio applications. Traktor's purpose in this application is digital feed and sequencer only. Recording goes to DP7, communication with DJM and  DP 7 is fine but I am not using the midi clock in DP7. I am not using CDJ's in this set up.  I Have written a *.tsi file to suit, all is good and it works great but I would like to control the tempo of Traktor using TIME dial 23 (manual p11).

I have set DJM as the midi tempo master and Traktor as slave.

Yes it does work, hold AUTO/TAP  (button 25) and change the BPM and Traktor responds but the problem is that it is not stable.

Traktor (slave) clock drifts continuously +/- 0.5 BPM either side of the value shown on the DJM (master) and never settles at a stable fixed value.

-DJM manual p16 says midi timing is sent regardless of I/O status of midi so signal should not be a problem.

There are 2 basic versions of this signal

Midi clock - this does tempo only and does not have phase information

Midi Time Code - this has tempo, position and phase information

 

THE MINOR QUESTIONS ARE AS FOLLOWS:

1)How do I stop the clock drifting?

2)The Audio Midi set up page (see pic attached) on the Mac Book Pro shows only Midi in 1 direction from the DJM, is this right?

3) Is there somewhere I can get tech and engineering help as this forum is not really "Technical"

 

THE BIG QUESTION IS THIS:

What is the format specs of the midi signal out from DJM?

I am not asking Pioneer to make any modifications or firmware updates to their system, but I do need information on the midi signal format to solve this problem my self and refer the info back to Pioneer.

 

 

Please help, this is a great studio application for the DJM200 and I really don't want to go back to the VCM-600 in the studio, please help me get this system right.

 

( For the record and before somebody gives the standard reply - Yes it has the latest firmware update installed)

 

Thank you

See this thread where I posted:

I just tested this with the 900 using Ableton and I noticed when set to external sync, even with a locked BPM of 128.00, I was getting readings of 127.93 and 128.07 BPM (which, mind you are quite small differences from 128.00).

Doing the math...

At 128.00BPM, it's 0.46875000 per beat (468.75ms).

At 128.07BPM, it's 0.46849379 per beat (468.49ms).

So 0.07BPM at 128BPM, is a difference of 0.26ms.

Even if you were to take the 0.14BPM swing over the maximum swing, that's a difference of 0.51ms.

MIDI has a variation of up to 1ms per signal ... so only having measured 1/2ms swing, I'd say that's pretty good.

There is no current fix for this but the engineers are aware of the issue.  It should be of note that the clock jitter in MIDI signal is very hard to tame and quite often requires very expensive outboard MIDI clock devices.
