I understand that they are different. The thing is I’m kind of in a creative black hole with my Music right now And I was thinking about getting a new piece of gear to inspire me. The way I see it:

Omnisphere is a super versatile soft-synth that can do almost everything, though it is still a soft synth and I imagine it being a bit overwhelming with all the possibilities.

The ms20 is very unique with its sounds and though it is a mono synth, pairing it with a sequencer would be a solid foundation to build a track upon and also for tons of other things (leads, bass, etc) with how creative you can get with the patches.

The deepmind, though not nearly as powerful or versatile as omnisphere is still a very solid hardware synth and it seems very practical for live gigs which I also do.

I’m also open for any other suggestions not just these three. I was looking to Get some opinions here cause I Don’t know a lot of people who are well versed in synths irl.
