Second-hand products

If you have purchased the product second-hand, please ask the seller to request a license transfer as explained in this article.

If you cannot contact the seller, you can still use your new hardware. Registration of the hardware is not necessary to use it. 

You can simply acquire the software separately to use with your hardware:

• Maschine 3
• Traktor Pro 4
• Komplete Start (for Kontrol keyboards)
• Native Instruments | Drivers & Other Files
