Denon MC4000 issues - asking help from the community

skinnyguy 9:28 PM - 12 January, 2016
I've already started a help ticket with serato but they haven't been able to replicate my problem so it's going nowhere. Perhaps someone in the community can think of something else.

Watchwww.youtube.com

Using the MC4000 and SDJ, I get random track re-loading on the side that is being cued. Sometimes the track is the same track, sometimes it's a random track from within the same crate. It has always happened on the track that has been loaded and being cued.

Sometimes when it happens, the cueing also switches sides, going back to the track playing over the mains. As evidenced on the video clip.

Using a 15" mbp with mountain lion (i think it's 2012). It's non-retina but has the dual vid card (I use ME). USB 3.0 and fw800. I've also upped the ram to 16 gb (previously 8 gb).

Also used it with another 15" mbp from a friend with 8 gb ram and pretty sure it was yosemite.

Also used it with a 17" with 8 gb ram ssd, clean install of yosemite and sdj. And a 13" mbp with yosemite.

Libraries have been all external. USB powered. 2.0, 3.0, and fw800. Also used a friend's library which was bus powered.

All files have been re-analyzed with SDJ 1.8.final. No corrupt files.

MC4000 has been returned and exchanged for a new one. USB cable has been swapped. Firmware has been updated (on old and exchanged).

Reset midi.

I've tested my lappy on a 6000 mk2, sx2, and a rane 62. At least hour sets and no problems. My sets on the 4k have been less than an hour and it happens. Some as little as 10 minutes in, other times it starts at 45 minutes in. But always happens.

Any ideas?
skinnyguy 9:28 PM - 12 January, 2016
I've also had it happen with Intro.

VDJ8 works fine.
Lou Dog 8:07 PM - 14 February, 2016
So I only use my MC4000 at one place I play at so its taken while to really get some hours on it. I will say I get similar weird shit happening on it too. Like it will just decide to switch the channel I'm cueing or just turn the channel I'm cueing off.

I dont get the same exact issue you have but definitely some strange shit happenin. I also had channel 2 lock up on me completely one night. The track wouldn't move and no audio on that side. It finally free'd up once i continually loaded song after song. Strange

Sorry, wish I had some actual help for you. Just letting you know you aren't the only one. Still having the same issue??

BTW im on SDJ 1.7.7 OSX 10.8.5
Lou Dog 8:10 PM - 14 February, 2016
Also after rewatching your video I noticed that when it reloads the MC4000 also switches the deck its cueing at the same time. Which is what mine is doing. Hope they fix these things cus I want to like the 4000. Never deal with anything on my 1200s and 62

I´m having the same problem with my Denon MC4000. I tried to change it for another one but in the shop they told me that this issue is located in the software or in the firmware, but not in the hardware, and I thought that this wasn´t true, but it looks like that this is really a problem of Serato or the firmware. My laptop is a Windows 10 one with an I7 processor and 8gb of ram and the software do this and it also freezes and has some dropouts at times, something that didn´t happen when I had a Numark Mixtrack Quad. Please Serato Support team we need a solution to this problem because sometimes the track that re-starts is the one that people hear and this is very uncomfortable. Thank you !
skinnyguy 1:22 PM - 15 February, 2016
Thank you! Finally, some validation that I'm not the only one with similar issues!

Update on my support. Serato has called me and even did a remote log in to see what was happening. Used snoize to watch for errant midi signals and found NONE. Very odd. It currently has been reported to devs higher up on the chain as a bug and we are still waiting to hear back from them.
skinnyguy 1:30 PM - 15 February, 2016
Nacho, when your track restart is on the song that people hear, is it because you are quick mixing and have already crossed the fader over? My problem is always on the track being cued but happens within a few seconds of loading the track, BEFORE crossing the fader back over. I know my problem would affect performance if quick mixing or possibly trying to drop a song on a live deck.
dj Technical 1:38 AM - 16 February, 2016
I'm having the same problem. It randomly loads a track on the deck that is playing when I do fast quick mixes. Also randomly reverses my headphone cue with other deck. Brought it back to store but they could not replicate it so I now have a $500 paper weight. Not impressed.
Jason.S 11:01 PM - 16 February, 2016
Hey guys,

We have had reports from this (as some of you may know) and have got some good information from those of you who have had this issue and opened a ticket. To help us investigate further anybody who has not got in touch with our support team yet please do! Drop us a ticket here; support.serato.com and the team can get into it with you. The more users and information we get the better armed we are to address the issue and/or communicate problems to Denon so please get at us!

To those of you already in touch with us please hold tight and keep working with us, I appreciate you all taking the time to get in touch and provide us with the information so far!

Thanks all,

Jas

I have opened a ticket but nobody answered me yet. Should I open a new one?
skinnyguy 5:21 PM - 18 February, 2016
Give them a while.....
nacho3322 5:44 PM - 18 February, 2016
Have you tried following the PC Optimization guide?
skinnyguy 8:02 PM - 18 February, 2016
i done did it all.
Chrisrome731 12:53 AM - 27 February, 2016
I have the same issue with 2 4000 units, the cue will randomly just to the other channel also randomly I will play a song and it will just stop and go back to the beginning and I need to start it over, it is totally random and can't pinpoint why running 1.81 on a Mac
skinnyguy 7:32 PM - 27 February, 2016
1.9 beta seems to have fixed this. i've had 3 1-hour sessions on it so far. seems like this problem is gone.
skinnyguy 9:32 PM - 9 March, 2016
seems to be non-existent in sdj 1.8.2 as well.
Savir83 3:23 AM - 7 July, 2016
Same here. I'll play for a good 30 min and just locks up. I can't use channel 1 load tracks,play samples etc. Channel 2 plays songs but can't use the jog wheel. I already updated my firmware and serato Dj. Serato Dj Intro works fine. Why is that?
skinnyguy 8:49 AM - 7 July, 2016
Those issues seem different from what I had.

problema con denon mc 4000 ase otra funciones carga la cacion en cual quier plato
samuel quiroz 4:21 PM - 17 August, 2016
Ya he empezado un vale de ayuda con Serato pero no han sido capaces de replicar mi problema por lo que va a ninguna parte. Tal vez alguien en la comunidad puede pensar en otra cosa.

Watchwww.youtube.com

Utilizando el MC4000 y SDJ, consigo pista aleatoria volver a la carga en el lado que se está con claves. A veces, la pista es la misma pista, a veces es una pista al azar dentro de la misma caja. Siempre ha sucedido en la pista que se ha cargado y ser complementada.

A veces, cuando ocurre, la pre-escucha también cambia de lado, volviendo a la pista que se reproduce sobre la red eléctrica. Como se evidencia en el videoclip.

El uso de un 15 "MBP con el león de montaña (creo que es de 2012). Es no-retina, pero tiene la tarjeta de vid doble (utilizo ME). USB 3.0 y FW800. También he subido la RAM 16 GB (antes 8 gb ).

También se utiliza con otros 15 "MBP de un amigo con 8 GB de RAM y bastante seguro de que era Yosemite.

También se utiliza con un 17 "con 8 GB SSD carnero, instalación limpia de Yosemite y sdj. Y un 13" MBP con Yosemite.

i never used CUE, but i had some freezes when using the "FX SELECT" knob.
i was mixing for an hour or so, so i thought i use some FX turned the know, CLICK, No sound anymore, tracks keep running, LEDS keep beeing active but no sound anymore. Have to switch of the Denon and turn it on again, then it continues..
very cool when this happens live...
im using a macbook pro 15" with yosemite but im sure its not the computer fault.
i would say its denons firmware. had v0017 from the beginning and there is still NO NEW Firmware :/ but all this software probs shouldnt happen with a console this expensive.
Like WE are the beta testers..
i mean, i had this issues since i bought it but i waited and was positive in a while there will be a firmware update but still after a year. Nothing. Lame Denon.. lame...
im using Serato 1.9.5 and im sure its not Seratos fault..
this is the perfect controller for me, size, channels, (dont need 4 faders,, who needs that ? 2% of all DJs ?? but if you tweek a know and bang SILENCE ?? thats not Hardware that you/ I want !!
hope this this will be fixed..

You can buy it (or your probably already did), it's an awesome controller.
DJ DanM 5:44 PM - 19 June, 2017
I have somehow the same problem. When I'm mixing tracks and I use a fader or EQ knob (filters, tempo or channel fader) the track will stop playing. Sometimes is the active track, other times is the track in the cue. Sometimes the cue button switches off. I noticed also when there's a loop in the cued track it resets to the start of the track, if I press re-loop it doen't go to where it was.
I can't any other indicator of what is happening. I tried everything. It occurs at least once for every 4 hours of play. Sometimes it doesn't happen so it's really hard to figure it out.
deejayfatcat 7:52 PM - 19 June, 2017
On a mid 2012 MBP Sierra and latest SDJ with a MC4000. No issues and recently did a 6 hr session with it. I did have to send mine in for repair with a jog wheel tracking, but it's been fine since getting it back. I hope you have luck figuring out what it is with you situation. I know it must be frustrating.
lexani 11:22 AM - 19 October, 2017
Hello,

yesterday I received my Denon MC 4000 and have noted following issues:

- When pressing the Sampler Pads several times, the left deck will stop playing.

- When pressing the Pad Mode button on Pad 4 (Loop Rolls), the samples are also played

It does not happen all the time but only after an indefinite time and makes the controller so useless for live gigs.

I am working with a MacBook Pro (13 inch, mid 2012) 2.5GHz Intel Core i5, 16GB RAM
Serato DJ version 1.9.9
bazooka 7:09 PM - 19 October, 2017
Well, now its Oktober 2017. And ?? GUESS. Still Firmware 0.0.17 ONLY..
These DENON Bitches hasnt changed a bit !
Yeah, its not all about new Hardware (MC 6000) and all previous Hardware is Obsolete !!!
Bitches ??
UPDATE THE FIRMWARE - DENON !!!!
This hardware is so cool, but with these slips and errors, i dont want to use it anymore.
I dont want to use the FX, since if i use the knobs (of course not straight away) the sound stops.
THIS IS NOT how hardware/software combos supposed to work. THEY SHOULD WORK! !!!
I mean, for real. Ive had this errors 2 yrs ago, and im sure, as proved here by other users, others had these errors too, but denon hasnt changed anything at all with their firmware ??

MAN FUCK:!.. sorry. im a bit aggro... These just proves that they just wanna sell Hardware.
I guess ill check the (half priced) Pioneer soon. And sell this 4000 DJ MC. What a name anyway. Sounds like sellout..
Thanks DENON!!! Piss off...
ps.
they should call themselves DENY !
NUdisc0 8:09 PM - 19 October, 2017
the last great Denon controller was the MC6000mk2, prior to InMusic's purchase...
lexani 10:58 PM - 19 October, 2017
It’s sad because this controller has so much potential and could be the perfect solution for mobile / touring DJs... but it’s not reliable for professional usage..it’s like playing russian roulette
jamdj 3:56 PM - 9 November, 2017
Hey Everyone. I'm a veteran mobile DJ here in San Diego, CA and have been using the MC4000 since it came out and have all the firmware and Serato DJ updates. I run a Mac Book Pro with the latest OS and don't use the laptop for anything else except gigs. I love the controller except, like many of you said, it will do weird things on occasion the biggest one is a track freezing or pausing in the middle of a set! I DJ'ed a huge wedding last week and it did that when I was playing "Poison" by BBD and people just looked at me with this collective "Ohhh....." and I have to restart the track. It was a little embarrassing to say the least. I can't figure out for the life of me if its the controller or the Serato DJ software. The cable is fine too. It doesn't do it all the time but it seem like it does when I have the volume playing loud when t the dancing get's started. Its REALLY annoying (and embarrassing). I will go to Pioneer or even another software if this continues. Any suggestions or answers anyone???
