I can't tell if this is a serious reply or not.

A quick look at Thomman would show you that they are all analogue polysynths not paraphonic mono-synths.

I think the only model from my list in short supply is the Prologue but you could swap it for a Dreadbox Nymphes if you like.

The Minilogue xd is "hybrid" only in the sense that it has an additional 3rd digital oscillator per voice but that can be turned off. It's still a true 4 voice, 2 oscillator analogue polysynth. If that's not good enough then swap it for a Behringer UB-Xa.

There's no shortage of models to choose from.

There's so much amazing music made with analogue polysynths. I don't know why anyone would ignore the work of Vangelis for instance. If you think he uses his CS-80 polysynth as a bad piano I don't know what to tell you.
