A good patch for the solo at the end of ELP'S "From the Beginning?"

Anyone? I'm being asked to play this but I don't have the synth/patch to accommodate. I'd consider buying almost any synth not named Omnisphere, but hoping someone knows of a patch on a "lesser" synth, paid or free.

It's a mini moog square wave, practically any subtractive synth could do a reasonable impression of it.

Actually it was a Moog modular that Emerson was using.
But any minimoog clone should have no problem either getting close.
