This sounds like a difference in the sampling frequency.  Music recorded at 48Khz must be played back at that frequency or there will be a significant difference in speed and pitch during playback at 44.1Khz. I first noticed this when it occurred to me when recording on digital audio tape.  Ipods and minidiscs and mp3 recorders can record at high sampling frequencies like 48K.  Cds are all recorded at the standard 44.1K sampling frequency.   Check the source of your recordings and it should follow a pattern that leads to your current results.       I do not have enough information  on how your music was transferred to tell you more at this time, but I am very confident that differences in sampling frequencies of your source material are causing the pitch differences you are hearing.   Without knowing exactly the sampling frequencies of each piece of equipment you used to record these songs it will be next to impossible to give you a very specific solution, so I hope the info. I have shared helps you to figure it out.  Best regards and good luck!   Michael Mittelsdorf

Even after callibrating my right deck, the pitch speed keeps jumping up and down... Any ideas how to fix this?


Hi,
you have to replace the Pitch fader, which is causing this .It requires taking apart the IDJ2 and desoldering it from its board. You have to be exprienced with a soldering iron. The spare part is not too pricy itself, so maybe swapping out 2 of these faders at a time and also replacing worn out switches as a maintenance step.

I want delete songs from idj2 pls help


There are no songs on the IDJ2
Only on your Harddrive / USb stick or Ipod.
If you want to play songs via the IDJ2, you need the librarian software for using the IDJ2 in combination with you songs.

IPOD TOUCH DOES NOT PLAY


instead of using your itouch in the ipod deck, plug it to the white cord used to transfer music to your pc, and plug it in the usb dock, it should work because i've tried it with the iphone 3g

Uploading problem


Some things you have to do yourself... It only takes some work to get it right.

For using ipods or harddrives/USB sticks with the IDj2, your best off with creating Numark libraries. This makes the IDj2 quicker when searching/loading tracks.

This can be done on your Mac or PC with
librarian 1.50/IDJ2 1.09(a)firmware combination. If you havent updated your IDJ2 yet, do so. It's the most recent verion, and fixes most problems...
Files can be found on www.numark.com/idj2. Look around in this page. There is also explained how to update with a FAT formatted USB stick.

If you have created a library before, Itunes won't update this library, cause it's made by Numark. Itunes and Numark use both a different database.
If you run Librarian, it will still see the Ipod playlists, and add them accordingly in your Numark database, and can be recalled in the IDJ2.
If you have created libraries with Librarian 1.33 or on the IDJ2 with firmware before 1.09. You have to remove the whole libary, and recreate one with Librarian 1.50.
Mostly there is a directory on the device called " .library ". You can throw this away, and recreate a new library.

Good luck and happy DJ-ing.

regards,
Jack.

I dj 2 will not down load t tunes purchased song


Hi,
Itunes downloaded songs can be AAC protected songs. These cannot be played on your IDJ2.
Luckilly Apple can offer a service(not free) for making your songs non protected.

When docking it takes too long transfering data from ipod to idj2


Hi,
if you have a PC, you're better of preparing a library for your USB/IPOD devices with Librarian 1.50, but only if you are running 1.09(a) firmware on the IDJ2. This is the preferred and quicker way...
Do an upgrade if this is not done yet. Go to
http://www.numark.com/contentmgr/showdetails.php/id/1230/tt/5
for downloading the files.

When rerunning the librarian(for instance when adding tracks), choose normal mode. It will add every playable track. (you could try this out on an USB stick with some tracks on it for testing purposes).
If this doesn't work, you could have a corrupt library, and have to rebuild(choose advanced in Librarian). Also, when you have created with earlier versions of IDJ2 firmware, then you have to rebuild the whole library.

Numark stated on their forums, when connecting a device, to never choose update, but load instead. It can use mp3/wav/non secured aac files, but not wma..
If there are any other questions, you can also send an e-mail to numark. They are reasonably quick with their responses.

regards

Jack
