Almost 300 gigs of samples…. And I have to say: the fraction of samples I find useful and of high quality seems rather high after perusing the first 3 or 4 packs - in contrast to stuff like Arturia's Analog Lab V, where I find the useful fraction rather low and the sound quality below average (though that's 6k presets for sw synths, not samples, taking up like 1 GB disk space). There is also no need to install them on an SSD.
Those packs/plugins may look like soft synths, but seem mostly rather frontends to the samples. The samples could be re-purposed and processed further in Falcon - which unfortunately is neither included nor exactly on the cheap side.
The clue: it's ilok based (no physical dongle), allowing 3 activations at the same time, and that also implies that you can sell it once you get tired of it. If paying the reduced introductory price, that will probably mean one ends up paying almost net zero if one sells it before the next major release…
The only downside I currently see: there is no common browsing frontend that combines all instruments in a decent way (like Halion, Omnisphere, Analog Lab …).
Pertaining to piano playing: I think there are a few neat instruments in there to provide one or the other accompaniment for piano improvisation/playing.
p.s. I'm not related to UVI, Arturia or any other music/sound related company 🤣
