With version 4, KONTAKT enhances its position as the professional's sampler of choice. Building on the outstanding features of the previous versions, including the unrivaled audio engine and state-of-the-art semi-modular architecture, KONTAKT 4 delivers new sonic horizons for your music.

An expanded sound collection connects you to an immense number of instruments, and the new Authentic Expression Technology (AET) is at the cutting-edge of dynamic and true instrument simulation. KONTAKT 4 offers endless possibilities to really get inside your samples. You can easily edit, loop, slice and time-stretch your sounds and pitch shift them in real time or tempo-sync them with the powerful Wave Editor. Draw your own custom envelopes directly into the sample waveform to easily and precisely modulate any parameter, or use step sequencers and flex envelopes to tweak your samples. Refine your sound even further with any of the 19 versatile studio-quality effects such as the convolution effect for super-realistic reverbs, or use the powerful surround sound features for cinematic.
