Overview
The Korg Mono/Poly, released in 1981, offered four voltage-controlled oscillators that could be configured for four-voice polyphonic or massive monophonic operation. This unique architecture provided flexibility unavailable from competitors, allowing both chordal playing and powerful unison leads.
The instrument featured a 44-key keyboard, arpeggiator, and comprehensive modulation capabilities including cross-modulation between oscillators. The filter and envelope sections provided classic analog character. The Mono/Poly's distinctive sound—particularly its unison mode—made it popular for leads and basses.
Korg manufactured the Mono/Poly until 1984, producing a cult classic that remains sought after. The instrument's unique architecture and aggressive sound have made it increasingly collectible among vintage analog enthusiasts.
