Here's a super clean example of one of Dave's best designs. This particular synth has been very well maintained along with the upgraded encoder kit (not PE) from DSI. True to it's original intended design, all encoders work flawlessly. Includes original power supply.
A Wickedly Powerful Synergy of Analog and Digital
The Evolver series marked Dave’s Smith’s triumphant return to hardware synths and still sets the standard for sheer sonic ferocity. The Poly Evolver Keyboard features a plethora of Dave’s best ideas packed into a monstrously powerful instrument with 4-voice polyphony and a sound like no other.
An analog/digital hybrid, the four-voice Poly Evolver Keyboard features four oscillators per voice—two analog and two digital (the digital oscillators feature the waves from the legendary Prophet VS). Classic Curtis analog low-pass filters and real analog VCAs add ample warmth and girth to the analog section while the digital high-pass filter, tuned feedback, and digital distortion provide sizzle and grit.
But what really sets the Poly Evolver Keyboard apart is the way in which the analog and digital sides of its personality mesh—the digital processing doesn’t simply add effects at the end of the signal chain, but is tightly integrated with the analog electronics in a true stereo signal path with tuned feedback, distortion, bit crushing, and synced delays. It can also process external audio and has separate stereo outputs for each voice. Massive doesn’t even begin to describe its sound.
Imagine being able to move effortlessly from thick analog smoothness to crisp digital edge—or anywhere in between—and you begin to get the picture. The LFOs, step sequencer, and three separate delays can all be synced for complex, evolving, rhythmic, time-based effects in true stereo.
