Dave Smith Instruments Poly Evolver

KeyboardHybridPolyphonic

Back in 2005, this synth took the bold step of packing four full Evolver monosynths into one keyboard chassis, blending digital wavetables inspired by the Prophet VS with genuine analog bite in a way few others dared.

Its hybrid heart features four voices, each with two digitally controlled analog oscillators hard-panned stereo left and right, plus two digital wavetable oscillators drawing from 128 VS-style waves for everything from precise riffs to evolving sci-fi pads. Those signals hit Curtis-style 4-pole lowpass or highpass filters that self-oscillate at high resonance, shaped by three envelopes—including a versatile third one with delay and destination routing—and four LFOs feeding a deep mod matrix. The 61-key velocity- and aftertouch-sensitive keyboard pairs with a 4x16 step sequencer for wild polyrhythms, plus onboard delay, distortion, and feedback effects; individual stereo outs per voice make it a dream for multitimbral setups or processing external stereo audio. Controls cluster efficiently up front: dedicated knobs for envelopes, filters, and sequencer steps, though editing combos means diving into the included software librarian.

Over the years, players have praised its vibrant, unique timbre—warm yet intricate, perfect for basses that thump and pads that twist—often calling it a secret weapon that stands apart from pure analog or digital camps. Some note the four-voice limit pushes poly-chaining with other Evolvers for bigger sounds, and the front-panel UI can feel compact for sequencer tweaks, but that hasn't dimmed its cult status among sound designers chasing the unconventional.
