I think rev 2 made it a bit more exciting for me. The cv to midi capabilities make it kind of handy if you have a use for that. The limited octave range is usually something people complain about, but it served a single purpose for me which is just low bass tones.
The portability is really nice as well, it’s far too easy to pack it up and go anywhere. I sequence everything from a single source which was an Octatrack, but now it’s Ableton so getting another piece of gear with a sequencer that I won’t use doesn’t have much appeal to me regardless of the tone (it’s just some personal pet peeve that sits in the back of my mind…likely related to OCD). I think what attracts me to other than it’s tone is that it doesn’t have a sequencer built into it. I had it in the past, and it punched through all kinds of systems when we played live, and has all that moog goodness. The minitaur is one of the few monosynths I miss and that I constantly battle with purchasing again.
