Audio examples

EPIK4 is a synth refill based on the sounds of KAWAI K4 synthesizer from 1989. It gives you the fuzzy but still warm sounds of the 90s – with a modern twist.

The K4 we used was only a raw material: the recorded samples were the starting points. We have exploited the specific features of REASON and created a vivid, live sounding library.

Most of the patches are velocity sensitive and have been designed to live performers, so a good remote compatible midi keyboard (with modwheel, control knobs and aftertouch) is highly recommended.

Extensive editing techniques

We used multiple velocity layers, multi-layering, alternate triggering and sample start offset to achieve fat and responsive synth sounds. In general, the modwheel controls the filter modulations and aftertouch adds vibrato effect.


  • EPIK4 requires Reason 6.5 or more recent version.
  • The NN-XT bank will work both in Reason Essential and in the previous versions of Reason, but most of the Combinator patches won't be loaded.
