The package includes the interface, a USB cable, a printed manual, a €25 e-voucher for use on the NI store and three discs-Cubase 5 LE, an Audio 6 installation disc and Komplete Elements (with 3.69gb of content and 1,000+ presets). As well as the S4, NI have now updated their soundcards, with the Komplete Audio 6 USB audio/MIDI interface replacing the Kontrol 1. The combination of software and hardware expertise results in some great bundles (the S4 packs a full version of Traktor 2 Pro) in these packages NI are able to give users greater integration, and better value for money.
Considering Native Instruments are primarily producers of software, they've built their fair share of hardware devices, like the X1 and S4 controllers for Traktor, and various soundcards, including the Audio Kontrol 1.
