Hi!

Lately my new cdj 400 (less than a month young) freeze while playing song (mp3 format)

It has happened to me 3 times already. may i know whats exactly wrong with CDJ. When i played the exact copy and location of the cd in another cdj 800 mk2 , no problems at all!

Hope someone can enlighten me on this. thanks

Probably a bad MP3. What's the bitrate and encoder used for the files?

even if its a very bad mp3 it has never a problem in my cdj 800...cdj problem likely?

Doubt it - probably just a different tolerance in the decoder.

Alow me to translate the pulsish.

Yes this is a cdj issue. ANYtime play stops- there is a problem that needs fixing. Please mandala, can you tell what the filename is and the size - is it a downloaded file, or did you rip yourself. As a fellow 400 owner i am more than curious.

Anyone else having locking mid-song? If only one person chimes in, it's not worth mentioning, as Pulse says. But if more, than he can actually do something about it.

LOL - no - chances are VERY good that it has next to nothing to do with the player but rather the MP3.

I'd bet dollars to donuts that his file is damaged somehow and the newer MP3 decoder chipset in the CDJ400 rejects the damaged portion whereas the CDJ800's decoder skips past it.

ok guys thanks for yrr prompt reply..

last nite i got this "freeze" again...getting kind of annoy now, jog down the exact location where it froze. Play it again on the 800..perfect no problem. Swop it back to 400, strange it went on quite well. Next track it freeze AGAIN.

My tracks are all from Beatpot and its 320kpbs...manage to talk to the Singapore Pioneer Technical service. They suggest its prob a unknown problem, need to send in for checkup..takes 3 days, and only open on weekends..wth?

With this being a new product I would follow their advice. The reading of the 400 may be effected by something, but I would be interested to see if the old LAME encoding issue is alive again? Let us know the outcome on it..

mandala i am interested in the file, what is the name? i will try and see for myself- worth a shot.

pulse you and i are agreeing and yet disagreeing.

i agree it's more than likely a problematic mp3 file, but my point is that if the 400 gets stuck and the 800 can handle it "no problem at all" (not skip past), then it's a problem with the player. The decoder in the 2 year newer player should be more effective at playing songs than the older one, IMO.

Not true. the DVJ for example had an issue with playing "dirty" tracks that would play on the X1 just fine. I had that happen with a 1000MK2 and a DVJ. The cure in that case was an update by Pioneer.

The encoder is newer and should handle everything it's given, but the mechanics involved are also being used in a newly designated manner. I will be interested to see if the next update addresses this, I think it probably will.

If you want to send me the file to try, I will be happy to do so.

Nice site Jay, I don't get the thrill kill connection but nice to see some pride in the husband /father role.

Heres my experience with my 4gb thumb drives after I filled them up. I had roughly 140 songs in that folder, once I got over 100 I was having problems. I now made two folders for that folder dividing the songs and it seems to have fixed it. If I would restart the player it would play better sometimes than others and I didnt change any of the songs I cut and pasted inside the drive itself so I think that rules out a corrupt mp3 issue, and it would happen to every song after it would happen to one. Also the one player threw a E-8303

I'll ask the engineers what's up with the "over 100" issue but why do you have over 100 files in a single folder anyhow?

Just to add to my post. If I remember correctly the manual sayes it can play upto 1000 songs from one folder. I find it a little annoying to have to go through two different folders to search for the same style of music, I really expected these to play solid from Usb drives. The players are updated to 1.12 software, and the Usb drives are Fat32, with then 4 folders specific to Genre, all 4 folders are in the root folder so no folder depth.

I had 4 folders, Driving Electro, Hard Electro, Electro, Minimal TechHouse. Now I have to Electro folders, A-M N-Z. I have each style of music in each folder so I can pick and choose what I want. Im used to using finalscratch so scrolling and finding a song is not a big issue to me, not through a hundred songs atleast. I would rather do that then try to remember what folder has what song in it. I have both of my drives the same.

That would certainly make it hard to find things.

Not to tell you how to organize your files, but have you considered breaking them down differently? Eg. I sort mine by the month they were downloaded (for online purchases), all Promo Only's are in their own PO folders, sorted by series, month and CD. What I wind up with are roughly 10 songs per folder and it's really easy for me to find things.

I really dont have a set in stone method yet. I was using Finalscratch for sometime, I got used to just making and saving playlist or groups of songs within that. I get new music pretty often so I think by date would work. But I would constantly be adding and deleting according to what I like or grown tired of. Everything I have is offline, I was ripping vinyls but I grew tired of that, and Cds are a waste in my eyes, and are really hard to find what Im looking for. I have it basically setup for my favorites in each of my own genres and will change them whenever I get new songs, old out new in. Thats what Ive got so far for the thumb drives. If I do really get into using cds I think your method would be great to flip through an album. Ill see what I come up with and find easiest to use. Thanks for the suggestions.

No worries - it's something I've been trying to perfect myself... I found that when I download more than a dozen MP3s in a month, I'll split them into "CD1", "CD2", etc - because I also burn them as audio CDs.

I've emailed the engineers, they're trying to find the problem about the 100+ MP3s.

Voicekoil,

Just to share, I have 2 directories on computer for every genre. A regular folder and within that an archive folder. (80's and 80's archive) I have a separate "hot" folder for every genre that is update able.

New stuff goes in there. (and that's single tracks I have decided are worthy - madonna - 4 minutes, or taio cruz - come on girl) Every month or 2 ideally, I put 10 - 20 "good" songs in, and do a quick review of the list. Radio stations will keep songs in heavy rotation for up to a year, referring to them as "recurrent" if they are not current anymore, but having good staying power.

Since I don't like to delete, songs that are garbage or just grow old fast go into the archive folder. Songs that stand the test of time go into the regular genre folder.

I am subscribed to Promo Only yes, but I remind myself that if I am playing at the club off of a promo only disc, that I am being lazy (because I haven't gone through and picked out the 1-4 songs off the disc worth playing.)

And since I prefer CD play, I do what pulse does as well, making a few discs "for the month". Same idea though, it's important not to just leave them in the cd case more than a couple weeks, in my case, because there are hip-hop, various dance, classics, etc on the same disc. The sooner I make the compilation disc the better. It may not be perfect but I can't tell you how much easier it is to play with the thought out compilation disc, either laid out by bpm or alphabetized by artist.

Make no mistake, half of the job is the preparation behind the scenes.

my problem is similar but worse...my cdj 400s freeze at random even when playing ordinary cds. the only way of restarting is to switch the power off. Seems to happen the more "intense the mixing" because if i just leave them alone with a cd playing it'll go for hours without freezing up. I've upgraded the firmware and everything. I'm now probably going to have to send it back under warranty, but was wondering if anyone else has had the same experience. old cds, new cds make no difference.
