DJM900NXS2 - Problème de rupture de connection USB

Achat de la 900NXS2 il y a 1 mois... Et le même problème depuis le 1er jour...

Voici la config :

DJM900 connectée au Mac en direct via le câble USB

2 CDJ2000 et Un X1 connectés via petit HUB à l'autre connexion USB du Mac

Voici la description du problème :

Après un moment indéfini, 30 minutes, 1H, 4H... La connexion USB reliant le Mac à la DJM900 se rompt, il faut un redémarrage du programme pour rétablir celle-ci... Peut importe le programme utilisé (voir test ci-dessous). Tout les firmware sont bien sûr à jour.

Voici les test effectués sans avoir trouvé de solution :

• Mac Mountain Lion

• Mac El Capitan Full Upgradés

• Traktor Full up-gradé

• Rekordbox DJ Full Up-gradé

• Autre HUB

• Mac Branché sur l'USB A, puis testé sur le B

• Set-up Mixer Output dans l'utilitaire Pioneer 900NXS2 sur Post CHx Fader - USB 9/10 sur MIX(REC OUT)

Je suis assez décourager... La seule solution pour être fiable est de brancher mon boîtier Audio 6 de Traktor... Ce qui n'est pas une solution en soit !

@Tkila > If you are having the same problem on USB A and USB B connections, this hasn't yet narrowed the problem. Be sure you are NOT using a hub for the DJM connection to the computer; connect it directly.

Be sure you have the latest firmware and correct drivers for your mixer and OS.

• No Hub for the DJM connection => Direct from Mac to DJM.

• I see that there is a new firmware made available today (1.10 ) but is this the solution ?

• Before buying the DJM900NXS2 I played on DJM900NXS with the same configuration and no problems...

The DJM-900NXS and DJM-900NSX2 are two different units and have different drivers. Please update and test again!

The DJM-900NSX2 update (1.10) has been made but it is still not the solution to my problem.

During my last mix session, after 50 minutes the connection shows signs of weakness and then the connection is broken.

Are you using the 2.0 drivers on El Cap?

What exactly does "the connection shows signs of weakness and then the connection is broken" mean? The audio quality was degrading or the USB connection had other issues? Please elaborate.

I have 2 Mac Book Pro => 1 with El Capitan Full Up-graded & 1 with Mountain Lion Full Up-graded Also (15 inch, MID 2010) => In the previous test I noticed that the problem was the same on 2 mac => I prefer to use the one with Mountain Lion.

• 2 USB 2.0 port

After awhile mix, audio quality degrades in the song that is playing , and then the connection is broken => no sound happens by the USB connection from Mac to DJM900NXS2 , sliders s' off. By cons I can immediately switcher to my USB key is the attorneys in DJM900NXS2

In French (because difficult for me in english) :

Après un certain temps de mix, la qualité audio se dégrade dans le morceau qui est en train de jouer et puis la connection se rompt => plus aucun son n'arrive par la connection USB du Mac vers la DJM900NXS2, les curseurs s'éteignent. Par contre je peux immédiatement switcher vers ma clef USB qui est dasn la DJM900NXS2.

Yesterday I had the opportunity to test with Buffer = 25 ... After 35 minutes I had to mix again Crash USB.

Rekordbox DJ continues to rotate, the CDJ also is the only connection that breaks.

Just before the break , while playing the previous song I hear the audio quality degrades and during the next mix is the crash.

I begin to believe that it is only my DJM which a problem because I see no other deejay with the same problem !?

I've asked our product team to investigate.

If you use the CDJs as the audio devices, do you have the same problem?

To avoid any problem during our benefit I work with an external sound card ( Traktor ) ... The intention is of course not having to use external sound card and play live in djm900nxs2 ;-)

Okay, so if using Traktor (not using the DJM connected via USB), does the problem persist?

With Traktor Audio 6 No Problems ! My Audio 6 Box is connected to my Mac with USB and my CDJ's also and that run very good.

There are problem only with direct connection from mac to DJM900NXS2 (with RekordBox DJ or Tarktor Pro 2)

Thanks for that additional clarification. I'll pass that along to our product team.

And just to confirm, this same problem exists with multiple computers?

@Tkila > The engineers would like to know the following:

・What is the status of the USB port indicator just before the disconnection and right after the disconnection?
・After the USB disconnection, how did the track playback of rekordbox dj change?
・What is the connection status of the INPUT/OUTPUT tab in the Settings Utility on the computer?
・After the USB disconnection, did it reconnect when some time passed? Or, did it remain disconnected?
・After the disconnection, try shaking or slightly moving the cable connected at the USB port. Does this movement change the USB port indicator?
・How do you restore after disconnection? Did you reboot the application? Or, did you disconnect and connect the USB cable again? Did you reboot the NXS2 power?
・Do you use the cable which was included in the box of DJM-900NXS2? Or, do you use other cable than that? Did you try using other cables?

Merci!
