Saurus is a Multi-Layer Resonant Filter for Kontakt offering a complex, analogue resonant-filter sound.
It consists of four separate layers, the two main providing a nice stereo sound with just enough detuning to make it fat, a separate sine-layer to make sure that the bass-oomph is always there, and a unique "buzz" layer, which is occasionally triggered to provide just a bit of rattle and buzz, so each note is a bit different.
There's a Kontakt script which implements a legato mode, much like most analog synths, where legato notes play without retriggering the sample or the filter envelope. A button controls whether it's polyphonic or in legato mode, both modes can be heard on the demo.
The mod-wheel is routed to the filter cutoff, and the Kontakt interface has knobs to allow other fiddlings, because this is a fiddling sort of sound.
Compatible with Kontakt 2.2.4 or higher.
