Hi I’m having trouble recording when using Serato & Numark mixtrack pro. I can record windows media player ok but when I try using mixpro it doesn’t seem to pick up the signal. I have tried all the settings on the the front & have a phono lead going from the mixer output to the computer headphone socket but nothing. Could someone help please?
Thanks 
Just to add I’m using Windows 8 & audacity 2.0
You need to set the recording input in Audacity (in the device toolbar) to record the appropriate sound input. When using the mixtrack pro, where does the sound come from? Is the sound produced by the mixtrack pro, or is the sound produced by your computer?
Thanks for the reply Steve.
I’ve tried both options on the record input.
First option… Speakers realtek high definition…
Second option…Speakers mix track pro…
I press start monitoring or record nothing happens.
I’m using serato on my laptop with the mix track pro through usb. I have stereo jack output coming out of the mix track into my aux on the amp.
I have no problem recording windows media player on audacity.
Any ideas?
Thank you.
I know about Audacity, but I know nothing about Serato or Mixtrack Pro.
When you record Windows Media Player, you are recording sounds that are playing on your computer. Windows Media Player plays files or CD’s that are in your computer and the sound comes from the computer sound card, and you can record that.
What does Serato do? What is Mixtrack Pro and what does it do?
(imagine that you are explaining to someone that knows nothing about it and you’ll be pitching it right 
)
Hi Steve.
This should be fun. I know very little about computers & electronics in general but I’ll give it a try.
Serato is a audio dj software which allows you to manipulate & playback digital audio files (MP3, WAV ect).
Numark mix track is a hardware mixing console that links into your computer which allows you to control the serato software & connects through a USB.
Is that any help?
Thank you
Dave
So where does the sound come out? From your computer’s sound card or from the Numark?
From the mixer. It has two jack outputs . One goes into my aux on my amp.
Next question
Is it “supposed to be” possible to record from the Numark mix track on the computer that it is connected to? (for example, does the Numark manual say that it can be done?)
Technically yes but only if you have software that’s able to do it. The serato dj software I’m using is called serato intro & doesn’t have a recording faculty. The next model up records as do most other dj software programs. That’s how I found out about audacity. People with serato intro mainly use audacity for recording but I’m having issues recording serato…Does that make sense?
Yes. It sounds like they have made it difficult so that you have to buy their software.
Ensure that the Mixtrack Pro is connected and switched on before you open Audacity. Then look in Audacity “Help menu > Audio device info”. Wait a few moments for the info to appear, then copy/paste the info into your reply.
Thanks for your patience Steve.

The only “real” inputs available are from your normal (Realtek) sound card.
“Microsoft Sound Mapper” is a kind of “proxy” for whatever audio device is set as the default in the Windows Sound Control Panel.

This input is probably your best chance of recording from the Numark, and that is what you currently have selected:
Selected capture > device: 11 - Speakers (3- MixTrack Pro) (loopback)
Selected playback device: 12 - Speakers (Realtek High Definition Audio)
Audacity sees the Numark as an audio device with four outputs and no inputs (because that is what the Windows Sound system says it is).
Does the Numark behave like a sound card?
If you import an audio file into Audacity and set the “host” to MME or DierectSound and set the output (playback) device to “Speakers (3- MixTrack Pro)”, are you able to play Audacity through the Numark? Have a play around with the options and see what works and what doesn’t for playback. Playback may be dependant on whether Serato is or is not running, so try it both ways. Also try changing the “Project Rate” (bottom left corner of the main Audacity window) and see if that makes any difference to playback through the Numark.
If we can work out exactly how Serato plays through the Numark, then that may show us how to record for it.
Are there sound settings / preferences in Serato? If so, how are they set?
OK. I’ve tried that & it could not get it to work.
I’m rather clueless when it comes to computers & the like but I’ll try & do my best to answer your questions… 
Regarding the sound card, I think it has. Numark is a mini dj mixing console with a headphone socket which enables you to listen to each deck separately. In the back there is two stereo outputs which you connect to the the amp for sound. I remember the shop assistant saying there was one built in. The mix track connects to the computer via usb. With serato running you have full control of mixing.
Could not find any options for preferences in serato either.
Just a thought:
Have a look in the Windows Sound Control Panel and see if the Numark is listed and enabled as a playback device. If it is, try setting it as the default playback device. I think that Windows Media Player always uses the default playback device, so if you can set the Numark as the default, play something long in Windows Media Player and then have a fiddle with the Numark and see if you can get Windows Media Player to come out of it.
Almost forgot - make a note (on paper) of all settings that you change - so that you can get back to how it is now.
I really appreciate your input Steve…
I had a good try with those setting but to no avail I’m afraid. At least I’m learning something new though… 
Just noticed this though. It might be of some help…When I select mixpro for input & then press pause & record, a message pops up…
Error while opening sound device. Please check the input device settings & the project sample rate…
I did check the latter…
I’ve been looking at the Numark Mixtrack Pro manual. It seems that they are using some specialised ASIO audio/midi drivers that interface the hardware to specific software programs including Serato, Traktor Pro, VirtualDJ Pro, UltraMixer, djay, PCDJ, FutureDecks Pro, Torq and MixVibes. There is no mention anywhere that I can find of support for standard Windows drivers, which is what Audacity would need to record directly from the Mixtrack Pro.
So then I looked on the Mixtrack Pro forum, and found this guide: https://www.dropbox.com/s/9clog1yspj1gzaz/Recording_Your_Mixes_in_Serato_DJ_Intro.pdf
That appears to be the best guide that you’re going to get.
You’re diamond Steve…I’ll have a look at it later & let you know how I get on.
Many thanks…
