NATIVE INSTRUMENTS TRAKTOR KONTROL S4 - Almost unused, in near-new condition. Includes a clear case to cover it. I received this from a composer friend, but recently had a DJ friend check its functionality. It mixes with excellent sound quality and is practically new/unused. However, I don't anticipate using it, so I'm selling it in its pristine condition. The USB cable and charger are sold separately, but according to my DJ friend, you can use your own if you have them. I will provide the download number for the control software after purchase, so you can download it to your computer and start using it immediately. There's also a free demo online, which allows you to mix up to four sounds, making it very user-friendly and producing a smooth sound. I believe this is a great item for DJs and musicians. #NATIVEINSTRUMENTSTRAKTORKONTROLS4 #TRAKTORKONTROLS4 #DJ #DJ Equipment
