This is the Native Instruments TRAKTOR KONTROL S3. I purchased it from OTAI RECORD about three years ago. I used it a few times at home (non-smoking environment, no pets), and haven't had a chance to use it since, so I'm putting it up for sale. I've checked it myself, and there are no major scratches or stains. Regarding the software (TRAKTOR PRO 3), it has already been activated, so please be aware that you will only receive the unit and the accessories shown in the photos. I still have the original box, so I will wrap the box in bubble wrap and ship it when you purchase it. Thank you. USB power has been confirmed using a MacBook Pro. I have also connected it to TRAKTOR PRO and confirmed that it works. Image 8 is a photo of the USB power confirmation, and image 9 is a screenshot of the screen when confirmed with TRAKTOR PRO. *The software is not included this time. Please note. *This is a used item, so please refrain from purchasing if you are sensitive to such things. We also do not accept claims or returns after the sale.
