The Volca Beats is an impressive little analog/hybrid drum machine with powerful sounds, but also some notable limitations even beyond some of the functionality constraints common to the whole series

Great little analog groove box

But with synthesizers - and especially affordable ANALOG synthesizers - true polyphony is actually somewhat rare.

Korg's recent adventure into classic analog electronics produces some interesting instruments and the Volca series first three releases, Beats, Bass, and Keys, are no exception.

That led me to look more at the overall landscape for affordable analog synthesizers (which, until quite recently, was a sentence that wouldn't have made any sense).

Hook up a $50 MIDI keyboard & you have a pretty decent analog synth.
