Multi-functional 4-channel DJ controller, Serato DJ compatible, with LED backlights. - Model: DDJ-SX - Brand: Pioneer - Connectivity: USB connection - Features: 4-channel mixer - Compatible Software: Serato DJ - LED Lights: Multi-color LED backlights - Effects: FX effect control - Pads: Performance pads Thank you for viewing. While it's Serato compatible, I was also able to use rekordbox. I personally used the paid version of Rekordbox. Other than the Deck 4 button not lighting up, I feel like there were no issues as I was using it until recently. I am selling it because I have upgraded my equipment. There are some scratches and signs of aging from use, but it is relatively clean. I will also include a deck saver. Please understand that this is a used item before purchasing.
