I use and love it because of this! I don’t have a large collection of synths, and don’t use a DAW or multitrack. So having four tracks of mono (or 2 or 3 if I use sóme occasional duophonic tracks) is perfect for me. Beats buying a different synth for each other part you write
To the OP: I can’t speak about high-high end Analog synths. But as far as I can judge I think that i agree with what most that is said: great to have a dedicated sequencer in every box (at least I love that), A4 not perse meant for polyphony first and foremost, but a great machine especcially if price comes into play. I love mine to death, first synth that made synthesis click with me.
Good luck with the quest!
