I've owned the Rev2 and I loved it but the Take-5 is an entirely different league. The overall sound is vastly better, the sound design capabilities are stronger & more flexible. You're really only losing 3 lfos and a looping aux envelope. it's not that big of a deal when you consider the mod matrix can patch many sources to multiple destinations and you can modulate mod slots. You get analog overdrive, much better effects (very usable, sound great. far beyond the unusable rev2 fx), extremely powerful fm, sine waves, much better filter, voice spread mod source for panning and other sources, better sounding vcos over the good sounding but very bright/harsh (imo) dcos of the rev2. The wave morphing, the oscillator sync, the fm are all much more versatile and musical on this synth.
I did like the Rev2 a lot, but i felt like i was constantly fighting to pull back the overbearing treble presence. It can do brass well, and it's beautiful, but the Take-5 can do brass better and so much more. You can get insane fm textures with pulse wave modulating a sine wave, which has a percussive clean tone as you strike it then decays into a gritty undulating powerful rich syrupy timbre.add overdrive to that and it growls. you can get clean koto sounds that you'd expect from fm, but also any type of evolving pad, great mono sounds, bass, patches designed for chords are exceptionally easy to produce.
I dont think you'll miss the 3 voices unless you really use 8 voices at once very often. I cant imagine you do with that timbre. and you may miss the looping envelope that retriggers on each press, like i did initially, but that wears off very quickly. It's a no brainer for me. Not only in terms of Rev2 vs Take-5, but I honestly feel like the answer to all of those threads from the last maybe 3 or so years about "Which Modern Polysynth Under $2000 Should I Get" is now, hands down, without question, the Take 5. The Digitone, The Peak, The Summit, The Hydrasynth , The Medusa, The Rev2, The Analog Four, the Argon 8, The Prologue, even synths above the $2000 range aren't even close in terms of the sum of the Take-5's sound sculpting ability + fx + mod parameters + interface + modern unique character + overall sound quality + quality of components + the interplay between all of these factors
I have no bias, i've just owned a lot of modern synths and i have never felt this connection with a synth, ever. It is mind blowing that it's only $1299
