Well let’s start by saying it’s NOT gonna be a tetra or a mopho x4, so you won’t get easy pleasing “typical” polysounds out of it, but then that’s not what it’s for. I used it a lot as a polysynth personally, I like a lot about it, the possibility to make it a dual two oscillator synth, or a 4 voices polyphonic synth with two modes (one “classic” where it goes in sequence to the next oscillator everytime a new note is triggered, and one where the oscillator pick is more random and chaotic, which I personally found myself using more!), there’s no sub oscillator per voice but it’s kinda crazy how fat it sounds without it so I would cross that as a non-issue, then there’s possibility to synchronize / desynchronize LFOs to eachother or make every oscillator an additionnal LFO (and if you choose to synchronise them, the possibility to make them interdependant by chosing that the next one is gonna be delayed from its previous oscillator by a subdivision of your choosing) this alone can help creating crazy texture with very slow or very quick oscillations in rythm. If you’re interested, you’ve noticed you’ve got independant output for each oscillator, which I use ALL the time to put different settings on each oscillators in ableton / protools, and then there’s the crazy beautiful FM knob, where you can use the previous oscillator to cross modulate with the next FM style and go completely bonkers with the sound palette. There’s still a lot I didn’t mention that makes this synth special to me, so, in substance, yes, it’s only 4 voices, and if you’re interested in a classic kind of keyboard playing, I don’t think it’s the ideal choice and 16 voices DSI synths will be the go to place, but if you want to tweak parameters in real time (ONE KNOB PER FUNCTION! It’s all layed out for you on the front panel and It’s the best, most fun providing, possible thing) out of a sequencer or create beautiful pads / drones / ambiant chords or whatever really (I actually use it for everything), I think it’s just a beautiful piece of instrument that takes inspiration from a lot of places and is absolutely thrilling. I’ve tried a lot of synths before but this one was love at first sound 
Damn I did just sound like a Vermona rep for a whole paragraph, I promise this was only sponsored by my love for this little thing!
