What is it that you don't understand?

> Yes, but literally none of them are doing analogue polyphony.

That's simply not true.

Korg Minilogue, Mililogue XD, Prologue, Behringer Pro-800, Sequential Take 5, Prophet Rev2, Prophet-10, Arturia PolyBrute 12, Oberheim OB-X8, Moog One and many more.

Polyphonic analogue synths are popular and very useful actually.
