I've owned ART Pyrite-K for just over a month now & have given it a pretty thorough workout & I must say that I am very happy with this kontakt instrument. It's full to the brim with hundreds of very usable presets which sound absolutely stunning. I won't go on about the myriad of ways you can further sculpt your sounds (just have a look at the 'main features' mentioned in the instrument description). You can lose yourself for hours just listening to & tweeking the fantastic presets. And on top of all that, you can get even more inventive with the 3 randomise buttons (1 to randomise the waveforms & another 2 buttons in the sequencer section to randomise the volume & tune). There is also an in depth, easy to understand manual provided. If you like creating rich, beautifully melodic soundscapes (like I do) then this is a must buy. Highly recommended.
