It's the kind of instruments that makes you want to experiment with sound. Cube is a clever sampler that can load up to 8 samples (even your own), it also features orbit movment that can be automated and create evolving sound. There's modulation, arpegiator and effects.
Cube is not quite fully developed, but that's not a terrible thing. Considering the possibilities and the fact that this synth is more focused on its unique mission, rather than being multi-purpose like many typical popular synthesizers these days (Like UVI Falcon, Omnisphere, and VPS Avenger), it is unusual that it stands out so much for so successfully achieving this end. Cube by Virsyn was sort of unique itself but broke things into partials and is quite a bit different.
Lunacy's Cube seems more like vector morphing, modulation synthesis. You'll have to check it out to get an accurate description because I haven't had time to dig in really, but I think most people will find it extremely good for cinematic and atmospheric work requirements (good for certain types of EDM and other music as well, sparingly.).
Definitely up there past 4 stars since this baby can so easily put out special and personal sounds, sedate ones, or even spicy ones if you import your own waveforms, which you CAN do.
The developers have suggested that they will add granular synthesis capabilities and some other exciting features, and I believe them, because this synthesiser has a buzz about it already and that will financially support (and encourage) further development. That's another reason for the 5 stars, because I sense from the quality here that this company is following through (they recently added User Waveforms to its capabilities) and can be trusted more so than a number of odd and esoteric offerings by companies whose concepts sounded promising but who left the user base to rot (I'm not naming any names Auddict with Hexeract Synth still at version 1.1 after 4 years.... or Amaranth Cycle Synth, etc.).
