Numark 4 Trak 4-Channel Traktor Controller

I've owned this controller since August 2013? Yea, about that time-ish, and so far, I've had a few minor issues that came up expected as this controller ages.One of my upfaders is finnicky and will occasionally "dance" down or mute, even when the controller is all the way up. I tried using contact cleaner to fix it to no improvement. May need to replace the upfader myself (about $20), though a bit of a ghetto fix I've rigged is to glue a card aligned against the fader's post as keeping constant pressure to the left on the fader's post seems to solve the issue (for now).One of my channel's hi knobs initializes to 100% to the right when it should initialize to the middle. I need to turn it all the way to the right, then the left, then back to the middle before I mix.The 1/4th jack on the front is unreliable. Not an issue since I usually plug into the 1/8th anyway.Overall, yes I've had some issues but given I've owned this controller for 2.5 years and the minorness of these issues, its still pretty good. Controller's a bit out of date now, you may want an auxillary controller (like a MIDIFighter) to control some extra stuff and maybe do cue drumming or whatever, but if you can find this controller for about $400ish or under, its still a great mid-tier controller, above entry level but maybe not quite where the DDJ-SX or Kontrol S8 or a CDJ setup are in the world. Would still recommend in 2016 if you're willing to pair it up with extra controllers if you want more buttons for cue points or stuff.EDIT: Review previously complained about Numark's lack of Windows 8 support. I'll leave my original review below for historical reasons, but as of now (Feb 2016), this controller has had Windows 8, 8.1, and 10 support.There's not much I can add in terms of praise for this controller since a lot of the previous reviews have covered the great points! This is a fantastic controller, and the price I got this at several months ago, $420, was absolutely a steal!There is one glaring issue however. The controller is not compatible with windows 8 as Numark has not yet made drivers for it, and previous drivers seem to have a fatal flaw. On both my laptop and my gaming rig, my 4Trak will become unresponsive to input after 5 to 30 minutes of use. The outputs including the lights and the music, however, will continue playing, so if you are unfortunately caught with an unresponsive controller mid-set, you can still somewhat save the show by controlling Traktor with your keyboard and mouse and do some basic mixing. I was on customer service with Numark (very friendly service by the way!) and they concluded it was due to incompatibilities with Windows 8. This was in September 2013 when I called. Its now February 2014 and Numark still has yet to release new drivers.In summary, hardware is fantastic. This will work perfectly as long as you're not using Windows 8 or 8.1.

I have owned this controller for a year. Originally was excited to have it...but after first gig the mic section stopped working. Don't know why but it just stopped. Had to use external mixer to run mics. Then about 6 weeks ago....started getting this strange metallic like ringing during a set. Believe it is a issue with the 4trak sound card. Connected a external sound card and ..........PERFECT PLAY BACK!!! The sound comes a goes with internal sound card...It isn't always present. Since I am a VERY busy wedding Dj haven't had the opportunity to send it in for repair. Currently debating on purchasing the Pioneer DDJ-SX2 since they have a Traktor mapping for it. For the money I have to give this controller one star because it just isn't reliable. Has a solid build (visually) but has failed in to many areas. Having owned other Numark products in the past...some good ...some HORRIBLE...this falls some where in the middle...but leaning toward horrible.

I have done a great deal of researching and deciding upon which controller I wanted. The 4TRAK seemed perfect and I thought I got it at a deal for $599 and this thing has a great build but is just terrible. I've come to realize that Numark has TERRIBLE customer service and they are taking their sweet time fixing the problems with this controller.I could only use the 4TRAK with Traktor if I didn't touch the jog wheels, if I touched them too much it would freeze up.EDIT 4/2/13: I waited on hold for 45 minutes before getting through to Numark and all they did was email me a setup guide which is already on their website... I scheduled them to call me back to the next day to use TeamViewer to see what was going on with my computer. They told me that the "load" bar was getting too full when using the 4TRAK. I have a pretty fast computer (although it is a 4 year old vista laptop) so I'm unsure why this thing is such a resource hog. I installed Traktor on a friend's Windows 7 laptop that's 3 years old and it worked great...If you have a fast Windows 7 computer (64 bit) this controller will work great but man there are a lot of bugs and it hogs a lot of resources... I was expecting more from this toy, but I'll have to suffice using it on computers other than mine unfortunately.Update:I seem to be getting a lot of hate and I'm going to update my review. Now that I have a better computer this controller works fine. It doesn't freeze on me but sometimes jumps for a second. I would definitely think twice before taking this to a live event. I usually need to "start setup wizard" to get the fx lights to work every time I plug it in. I really was expecting more from this controller but now that I've gotten a better computer I haven't had nearly the magnitude of problems I was.
