Feature:
Did I mention all the bells and whistles and pre programed mixer effects found on systems used by the best out there? Want to add reverb, delay, flange (basic stuff) or be able to tweak the x and y axis of sound while being able to store pre slect start/cue points and loops? If you answered yes or "dun no" to any of the above, then Tracktor deserves a look. There are better programs out there but (1) big bucks (2) you would probably be using them for a living since the learning curve is steep.

Quality:
I've used PCDJ before and Tracktor is in a league of it's own. Others can not compare. And the price... you cannot beat it!

Value:
Big bang for the buck. Less then 100 bucks and you are rocking (depending on your computer system, sound card, etc..).

Desirability:
Hell yes I want it. I will get a back up computer system for my rig and Tracktor will be on it!

Sound:
Allows customizing to work with many computer systems (external/internal; clock sequencing, etc.) without having to have a computer degree or much of a computer background. If you can install the program, odds are you will get it to work with your system. Plus, a lot of online help through Native Instruments. Many features that will satisfy the novice to creative DJ that likes to experiment or needs effects and an array of built in mixer settings found on the most elite mixers out there. Whether you are a closet DJ, week-end warrior or somebody hitting the road and clubs…this program could be the tool for you to take it to the next level.

Ease of Use:
Rip in MP3 or I tunes... tell the system where you store you music and it imports all your songs for you. Will not recognize WMA files (go figure). Playing around with the program helps alot... don't be afraid you will not break it. I did run into a few time and output issues at first, the support team helped me pull my head out. I haven't bought the "training DVD" and have been doing great. I did catch a few online samples from Native and did like how they made that tool so anybody can quickly use the system without wasting a weekend in the manual.

Support:
Okay, I've only contacted them once. I was having a mental lapse and they were very understanding and helped me out without slapping me in the face with a standard insult such as "next time check out our FAQ section in our web page" (which I've got from other places).

Overall:
Looking for hole in the mighty armor ... I hope Native makes future upgrades so Tracktor can work in newer high speed systems (not just a 32-bit compatible environment to operate under 64-bit versions of Windows XP/Vista).

Feature:
i used serato before and it is way behind traktor.this software rules.u get to use effects we used to find only on high end mixers.for $99 u get a value i've calculated at $1800 without all the extra hardware.

Quality:
nothing beats traktor.the germans have done it yet agin.first on my Bmw now my Beats.

Value:
well worth it.paid 299 back then but then i charge $600 per gig so i'm good,i have a regular it job but dj on the weekend and man this extra cash works well for me.if i do friday and saturday.that's 1200 easy.

Desirability:
it's hot and looks professional

Sound:
the sound is amazing.it can't get better than this.i'm using a macbook and the audio 8 dj due to it's ultra low latency drivers and hardware.people have told me time and again my music sounds amazing and i know why.those of you using windows,forget it,windows is not reliable with this software,i did it be4 and i tell you macs rule.i can use the highest settings possible with a gap of only 2 seconds of latency.i tried 1 sec too and it worked well for me on a regular macbook not even a pro.

Ease of Use:
i'm giving it a 7 because man you need to study traktor for months to get even halfway as good as guys like dj feli fel that use it.because it replaces alot of hardware,alot of time has to be put into traktor tutorials as well as practice.if u r creative this is the software for you.

Support:
excellent support all around.

Overall:
as long as it exists

Sound:
the sound quality is exellent, making it possible for users to select their buffer settings. It goes very well with the music I play. this product is perfct for me and I wont stop using it.

Feature:
can you really ask for more? the only more fully featured DJ tool is ableton live, but that requires serious prep.

Quality:
everything is awesome except those hiccups in audio. unfortunately that is a big deal when you are performing!

Value:
you get a LOT of stuff for what you pay. FX, key switching, locking, looping, built in recording, waveform overview, and all for less than the price of a single CD deck!

Desirability:
sexy, but needs to get the hiccups fixed.

Sound:
occasionally drops the audio stream just for a split second on a G4 1.5 powerbook, even when no FX or key lock is running. it's hiccuped during a live show before, and happened twice in 5 hours of play. but the key lock sounds great and the FX are awesome.

Ease of Use:
interface takes awhile to figure out. key/midi assignment scheme could be way easier. but once you get past orientation and setup it's all smooth sailing.

Support:
NI is okay for this product. had a problem with my playlists, and the tech responded the next day and i fixed my problem, but i had to reinstall it.

Feature:
I'm sure there must be some features for the future of this software so I give it a 9. I'm using it with a new Vestax VCI-100 and so far it seems perfect. The Vestax offers knobs and sliders for many of Traktors features and this makes the software much more useable. I do not think I'd want to DJ with Traktor using only a keyboard and a mouse... that would be rough, but I've heard of people that do it.

Quality:
I have not experienced any crashes in Traktor yet after about a month of using it. This is surely the mark of excellent quality.

Value:
Granted, this software essentially replaces several thousand dollars of equipment, I still think it's retail price is a bit ridiculous. I think you could easily make your money back by DJ'ing a few times. I think it's easy to perceive the Traktor software as being a toy when it really does have a fair amount of engineering behind it.

Desirability:
My main appeal for getting this software is to eliminate all the records I have around the house. I love playing vinyl, and I love the feel of it, but I do believe that that experience can and will eventually be replicated in such a way that records are truly never needed again. I just don't like the space that my records take up, I don't like moving them from house to house, and I don't like the fact that they degrade over time.

Sound:
These people talking about audio hickups are clearly not using a good audio interface or they are using a PC with terrible hardware. I have a PreSonus FireStudio 26x26 and I run Traktor 3 at 96kHz sampling rate on my mac pro and it sounds and works flawlessly.

Ease of Use:
The sheer amount of information on the screen at any one point in time can be considerable, but the interface is so configurable that it's hard to knock it for that. I give ease of use an 8 because of the learning curve. If you know your way around several makes and models of mixers already, then you should have no problem getting a grasp on everything very quickly.

Support:
Excellent support.

Overall:
I have been very very satisfied with Traktor overall. It allows me to DJ the way I already know how to with minimal fuss. Now that I've added the Vestax interface I have a similar physical experience interacting with Traktor and I no longer need all the records.

Sound:
Good Sound but the hiccups kill it for me. Any product, no matter how good the interface and userability, will be of no use if the output is even the slightest bit off. Sorry, but computer DJing is not all there yet, and most likely will never be as good as with using CDs.
