I owned the traktor kontrol S4 MK2 ,now I updated to the traktor S3, and have being using the traktor software since the beginning and I am still a big fan. waited a long time for Traktor Pro, the software still solid and stable but with needs of new features.
1. Stand alone hardware with a hardrive and battery power.
2. Touch screen
3. Song suggestions
4. Stem separation
5. Video mixing
