I had purchased the Numark MixTrack from GC back in August, but soon after I had seen that the American Audio VMS4 was coming to Guitar Center and I wanted it. I had done my research and like what I read about the VMS4. After about a month I went back to my local GC and trade up from the MixTrack to the VMS4. What a marvel, a built in sound card, 4 channel mixer with each channel having their own eq�ۡ���s, the ability to either play 2 turntables or other media players. Adjustable cross fader and is Innofader friendly. Metal Jog wheels, multiple hot cue points, dual mic inputs, XLR Balanced speaker outputs and RCA outputs for both booth and master. Fader auto start for auto start compatible CDJ�ۡ���s. The list goes on and on. Now for the bad news, for such a robust system why Virtual DJ LE, I was very dissatisfied with VDJ LE. For what this baby can do and for the price you pay American Audio should have commissioned Atomix to produce a more complete software bundle to take full advantage of the VMS4 from point of sale. You can switch to a full Demo of VDJ Pro for a 20 day use. If you can buy the VDJ Pro I strongly suggest you upgrade. Fortunately I have a copy Virtual DJ Pro to take full advantage of the VMS4 capabilities and I am very satisfied with it. In the near future I am looking to purchase a CDj maybe an American Audio Radius 3000 if the price is right to add to the VMS4 and some powered speakers. Thank you Guitar Center.

I owned one for a bit and it was subpar... anyone who has been Djing for a while will notice its faults right away. First, the internal sound card is terrible. Horrible, very soft, low quality output. This is a huge problem for anyone who wants to use it outside the bedroom! Definitely not for professional use. The cross fader has a 1/4? delay in action for both audio and midi, making it impossible to do fast cuts and crabs accurately (trying to scratch is a joke on this). The jog wheels are fairly flimsy and hard to get a super precise cue point. All of the backlit knobs have that little red light which I thought would be great for a dark club, it wasn't. It actually made it harder. The other thing is that it comes packaged with Virtual DJ LE, not pro. So if you want to be able to use all four channels you need to spend another $200 for Virtual DJ pro. Bottom line: I was very disappointed in this piece and there were just too many little problems that arose that made it an all round bad piece of equipment. Guys, save up a little bit more and get the Native Instruments S4 or the Denon MC600! It's really not that much more and worth it 1000 times over. Hope this helps! ps: If you ever have a problem with the vms4 the support team is terrible and may not even get back to you.

HORRIBLE Item and Support

By Conner Flisnik

from Boston MA

Comments about American Audio VMS4 - Velocity MIDI Station/DJ MIDI Controller:

First off I will say the VMS4 is listed for a great price for the abundant capabilities the unit is intended to provide. Although, I had the unit for about half a year when all started to go bad.... The cue buttons began to fail, The wet/dry effects bar did not work and the headphone cue volume was insufficient. Overall I am completely dissatisfied with the units performance along with the support from American Audio. I was in contact with the for half a year attempting to resolve the issues. Finally, when I sent the item in they decided it was then over 1 year warranty period and explained they could not help me. I will not buy American Audio dj equipment again and promote others to do the same.


Great unit once its tweaked

By Rockitt

from irving, tx

Comments about American Audio VMS4 - Velocity MIDI Station/DJ MIDI Controller:

The thing about the vms4 is that while it -is- a fully functional 4 deck mixer, 2 mic out, 2 xlr, RCA, analog and usb, with just enough mappable functions to do whatever you would like it to; this most definitely does not come plug and play. The first thing you want to do if you get this device is find a good mapping for it. Then tweak it exactly to what you need it to do to your software of choice. This is a great entry level piece and even enough to use at some lower clubs, but as a professional piece i wanted a lot more reliability. If you want to take the time to find a good mapping and really get into it, this can be a great piece. But if you just want to plug and play and learn to dj, this unit has quite the learning curve which may or may not be a good thing. The one great thing about it is its durable metal casing, no slip bottom, and all top lit knobs for dark atmospheres. Easy to see in clubs and definitely will not go anywhere. a little heavily for mobile, but as long as you can lift 20lbs you're good. Sound card could be a lot better. you may be turning your gain up a bit in some venues. Overall, its decent for the money once its set up and you start to feel like you can rely on it.

Comments about American Audio VMS4 - Velocity MIDI Station/DJ MIDI Controller:

dude... for starters Virtual DJ is absolutely the worst software on the market. The VMS4 & VDJ have some major mapping issues... Im having major problems with my cues. I cannot cue one deck to preview the song with out playing both at the same time. VERY frustrating. Ive tried all the firmware updates & mapping downloads...& no luck. The vms4 is a great controller.. all the control you need for beginner/intermediate djs. very solid and responsive. Final thought. Save your money and get the Traktor S4!!

Great for the Money

Comments about American Audio VMS4 - Velocity MIDI Station/DJ MIDI Controller:

I use this for school dances and all my smaller stuff that I do. It is amazing for the price. Super portable. I got the Odyssey case with it completely worth it. Plug and play works great never a problem. I use it with a Macbook pro 6.77 ghz processor. Great for any DJ.

I was looking for some high quality turntables...

By Tanner R.

from Orange County, santa margarita, CA

Comments about American Audio VMS4 - Velocity MIDI Station/DJ MIDI Controller:

And I found even better! Okay, so I was looking into buying a few turntables all the reviews that I read was saying stuff like "very high quality," and "HEAVY duty, it�ۡ���s the real deal!" and let me tell you, IT IS! Upon opening the box, I immediately new this decision to make this purchase was not going to be regretted and here�ۡ���s why: Pros: Plug in and play, out of the box! Has a ton of MIDI in/out capabilities. Truly built heavy weight, without weighing that much. There "special" vinyl decks are actually called "special" for a good reason! Scratching was so easy to pick up a 3 y/o can learn. This has different sound setup capabilities, 2 different mike inputs and tons of effects/ sounds (and you can make custom ones) Headphone jack! much much more!!!! Cons: a little complex for newbie�ۡ���s, but I learned so I guess you can too! Nothing else I can think of, I'd say it�ۡ���s worth the price completely.

Has it's ups and downs.


from Middlebury, CT

Comments about American Audio VMS4 - Velocity MIDI Station/DJ MIDI Controller:

When we first purchased this controller I was pretty pumped about the 4 assignable channels, multiple mic inputs, and the over-all appearance of the controller. When we got it out of the bag it was heavy and felt good for a controller. The casing is completely metal, which brings peace of mind. When we first started using it there were some things I wasn't pleased with regarding the mapping to VDJ (beginners beware... read forums on how to do this) and the over-all sound is definately lacking. There is a lot of ground noise and there is a known problem with the mic inputs. In order to solve the mic problem we just run this controller through an independent Mackie mixer and run our mics through that. Works fine. ADJ actually offers adapters at no charge to resolve the mic problem. We ordered them over a month ago, still haven't arrived. Meh. The sound problem is actually a gain issue. The levels coming off the mixer are just way too low. Obvious answer is turn up the gain, and then you immediately redline... Very frustrating and after checking into it I am not the only person with this problem. Last but not leaast the fader could use some work. It's not really repsonsive enough for advanced scratching, but then again most controllers aren't meant for that anyway. After all this you'd think I'd hate the thing, but I'm actually still a fan. I wouldn't use this for a wedding or anything too formal, but if you're just setting up in a bar it's alright. Once you start cranking the music you can't really hear the ground noise, and it's actually not a bad idea to use an independent mixer anyway. The mixers in this class of controllers aren't typically top of the line, or anywhere near it. The 4 inputs are really a great idea, especially because you can run them as auxillary in any fasion you wish, the platters are very responsive, and the play/cue buttons seem like they'll have a good shelf life. The layout of the mixer is very well done. I almost never accidently hit a platter. It looks pretty solid in the case, it sets up in less than 5 minutes, and you're not sacraficing a ton of features in the name of portability and price.

By Phil

from Orlando Florida

Comments about American Audio VMS4 - Velocity MIDI Station/DJ MIDI Controller:

The AA VMS 4 is certainly worth it's price tag, solid construction, user friendly and looks worth at least twice it's price. Once set up with Traktor Pro this is the only mixer you need. Before this I always had to take another mixer with me for live shows, now I can use the VMS4 for mics and even put turntables and cd's into the unit, eliminating a second mixer. (always take a back up mixer though) The biggest "plus" of the VMS4 like the much more expensive Traktor S4 is the four deck function that can be used with Traktor. Having four decks on a live show especially a wedding or similar, takes away the grief of 'lining up"the programme. To get the most oout of this unit you must use Traktor Pro os something of that calibre, Virtual DJ just doesn't maximize this controllers or your ability.


Versatile, easy to use, and great for the Money

By guy

from Portland, Oregon

Comments about American Audio VMS4 - Velocity MIDI Station/DJ MIDI Controller:

I am a beginner at live mixing, but it is my opinion that this controller is very functional and very useful for the price. I did a lot of research before buying and the VMS4 supposedly exceeds what people might expect from an American Audio product (although I wouldn't really know) Anyways, its is very easy to use and get professional sounding results even without much experience. The one problem I have had was trying to map the jog wheels into Traktor Scratch Pro, otherwise is works great.

Good Investment

By DJ Dirk Diggems

from Tampa

Comments about American Audio VMS4 - Velocity MIDI Station/DJ MIDI Controller:

I just recently Purchased Th VMS4. To my surprise, it is worth every penny that I spent on it. Once mapped with Tracktor pro, it works like a champ. Full midi control over files on my HD.Say good-bye to all those CD's. However if you still have anolog gear The VMS4 Doubles as a Anolog mixer.
