[SOLVED] Help Recording With The DJM-900nexus

Think I can see what your problem is Eduardo. In the DJM900 settings utility, make sure that on the Mixer Output tab, the drop-downs are all set to REC OUT. That's the only thing I can see wrong above, as you haven't mentioned it. Pic attached as follows:

@ ShortSTACK > Thank you.  Yup; currently on the Mixer Output tab (DJM-900nexus Setting Utility) ALL are set to this...

USB1/2: <-- Post CH1 Fader

USB3/4: <-- Post CH2 Fader

USB5/6: <-- Post CH3 Fader

USB7/8: <-- Post CH4 Fader

I will make those modifications and I will post the results.  Thanks again.

@Eduardo > There are a few threads on these forums where there are in depth explanations on setting up recording with the DJM-900 and Audacity. It's always good to search the forums first before posting a new thread. ;)

Also, you only need to change the output on channel 1/2. Not all of the channels need to be switched to REC OUT unless you plan on recording 8 channels? lol

@shortSTACK, yeah that's probably it, but only need to switch  channel 1/2 to REC OUT  if you want to record a mix and not all of them. ;)

@Foster > Thank you, I did search before I posted and did find several post but most of them talked about issues withis guy, what's his name? oh yeah Fuzz.  BUt none of the posts really explained in detail how to record on using the DJM-900 nexus.  The cosest one was the one posted by Pulse but it uses the DJM-2000.  I followed those steps before posting but the Setting Utility is differnt do no mention of the channel 1/2 to REC OUT was mentioned and of course I was missing that step.

Now, let me ask you this since I still don't understand 100% how this Setting Utility works.  My CD players are connected to Channel 2 and 3 (Line).  Do I only need to set USB1/2 only?  I guess I dont understan the relation between my channel up-faders on the mixer and the USBn/n channels on the utility.  Please explain?  Thank you! 

@Eduardo > Hmm, I figured one of the threads I left a long comment on would have shown up. lol I can find one of the descriptions I gave before if you would like more info on it?

On the physical mixer, you do not need to set the channel to anything so it will record.

In the "Mixer Input" section of the DJM-900 Utility, and on the picture I attached, you can see there is a small picture on the far right that shows what the channel is turned to. i.e. Digital, CD, Phono, USB

This is how the audio will enter the mixer. In your case, since you have 2 CD players connected to channels 2 and 3 (line), you will need to make sure the channel 2 and 3 selection is turned to "CD" or "CD/Line" it might say. Since you are not using channels 1 and 4, you can turn them to either "Digital" or "CD" too preferably. Then you are done setting the "Mixer Input" settings.

Now on to the second setting and picture I posted "Mixer Output". This is for audio that will be sent to the computer for recording. Preferably use Channel 1/2 in the DJM-900 Utility, and click the drop down menu and select "REC OUT". Since you are only recording a mix in stereo, you will only need those channels (Right and Left audio of 1 track). Setting this in the "Mixer Output" does not change or disable your channel 1/2 on your inputs. You can still add another CD player to channel 1, and still be able to record. This is because you have an 8-IN/8-OUT sound card. 

I would also recommend using either the -19dB, -15dB, or -10dB before trying the -5dB immediately. If you have it at -5dB, this means your DJM-900 will start clipping the audio in Audacity if you put it too high. Using a lower setting allows you to increase the volume of your DJM-900 more so you can hear it through your monitors better, without being worried it will begin clipping with the recording.

In Audacity, you will need to enter the preferences and select to use the DJM-900 as the main source for recording, and make sure you set it to 2 channels/stereo. This means only channel 1/2 from the DJM-900 Utility will be recorded, which is what you want. :)

If you wanted to record more channels, you would need to set it within the DJM-900 Utility, as well as add more channels in Audacity.

I think that explains it in some decent detail. :) Please let me know how it goes and if you get it working. 

Ahh!  Much much better, thank you!  After this explination I understand it much better.  So, with that setting, it does not matter how many CD players I have and where they are connected, ONLY channel 1 and 2 will be recorded from ANY of the input channels. 

For example when I am playing CD1 (connected to input channel # 2, and channel up-fader all the way up) channel 1 and 2 (L&R) of the track will be recorded, the same will happen when I am playing CD player # 2 (connected to input channel # 3, and channel up-fader up) only channel 1 and 2 of the track will be recorded.  right?

Where can I learn more about the different options in the pull down menus?  For Example, I know now what is REC OUT for, but the rest of them?  They are not self explanatory and the user's manual just list them but does not tell you what are they used for and why or when you would set the channels to one of these... CH1 Timecode Phono, CH1 Timecode CD/Line, CH1 Timecode Digital, POST CH1Fader, Cross Fader A, Cross Fader B, MIC, REC OUT.  and why are there four channels for it?  are the outputs channels,  realted to the input channels?  That was my confusion, that I needed to set to REC OUT teh corresponing channels to input channel 2 and 3.  I am Using Serato with control CDs and I am wondering if I need to set any of this to other than POST CHn Fader.

Thanks Again.

@Eduardo > No not at all. lol

Think of it like this... When you set Channel 1/2 as "REC OUT" in the "Mixer Output" tab, you will record everything that comes out of the "Master Channel" of the mixer. the "REC OUT" means the "REC OUT" which is an actual output on the back of the mixer.

You can set the Channel 1/2 to "REC OUT" in the "Mixer Output" and it will pick up your entire mix that comes through your speakers, no matter how many CDJ's you use or how what channels you use them on. ;) Provided you have your other input settings correct.

The other settings are to do different type of recordings. They do exactly as the title says... Mic = Audio from Microphone, Cross Fader A = Only Audio from Cross Fader A, same with CF B, Ch1 Ch2 Ch3 and Ch4 are specific to that channels input and the source of the input.

Nope you don't need to change anything as long as you're just recording a mix. If you want to record a mix, just set the Channel 1/2 in "Mixer Output" to "REC OUT" and it will record what ever comes out of the Master channel. :)

@Foster > Well, guess what?  That was it, all I had to do was to set USB1/2 to REC OUT.  Now, I can record my mixes.

I went back to Club Setup and changed the Digital Master Out Level to -15db (or -10dB) and Digital Master Out Sampling Rate to 48KHz.  In Audacity I set the Sample Rate to 48KHz and the Sample Format to 24-bit.  I am happy with the recorded 5 minute sample I did with those settings.

Thank you very much guys for all your help.  I am a satisfied Pioneer forums user.

@Eduardo > Thanks for the update and glad you got it working properly. :)

Enjoy!
