Description

Transport your music production to new sonic realms with the KORG MonoPoly plugin, a digital reimagining of the iconic 1981 analog synthesizer. Celebrated for its innovative design, the original MonoPoly pushed boundaries by offering both monophonic and polyphonic capabilities—delivering a rich, multi-voice sound experience. Now, this legendary synth is reborn in a software format, perfectly blending vintage charm with modern digital precision.

Harness the power of four VCOs (Voltage Controlled Oscillators), each capable of sync and cross-modulation, to sculpt sounds that range from lush, evolving textures to gritty, punchy leads. The MonoPoly’s versatile architecture, including advanced chord memory and a dynamic arpeggiator, empowers you to experiment with a vast array of tonal possibilities. Enhanced by KORG’s proprietary Component Modeling Technology (CMT), this plugin faithfully replicates the original’s electronic circuitry, capturing the intricate nuances that made the MonoPoly a staple in the synth community.

Designed for today’s high-resolution displays, the MonoPoly plugin features a scalable interface that seamlessly integrates into Retina and 4K environments. Dive into a comprehensive sound library with 300 meticulously crafted presets, or explore your creativity by leveraging the 8-way virtual patching and 21 high-quality multi-effects to push your sound design to the limit.

Critic Reviews

Korg Mono/poly

soundonsound.com

The KORG MonoPoly synthesizer offers a unique blend of features that appeal to both vintage enthusiasts and modern musicians. Its four oscillators provide rich, complex sounds, particularly in monophonic mode. However, the polyphony is somewhat limited due to shared filters and envelopes, leading to a thinner sound when playing chords. While the arpeggiator is basic, it delivers enjoyable results, and the synth's connectivity options are commendable for its era. On the downside, potential reliability issues, particularly with keyboard contacts, may deter some buyers. Overall, the MonoPoly remains a fascinating and capable instrument, but it may not fully satisfy those seeking robust polyphonic capabilities.

Korg Mono/Poly (EMM Apr 82)

muzines.co.uk

Korg's Mono/Poly synthesizer offers a compelling mix of monophonic and polyphonic capabilities, showcasing a robust build quality and a rich array of features, such as four voltage-controlled oscillators and an impressive modulation section. However, its somewhat plasticky keyboard construction and limited polyphonic functionality may deter some users seeking a more premium feel or full polyphonic experience. While the pitch-bend wheel's weak return could pose tuning issues, the overall sound versatility and ease of operation make it a worthy contender for both studio and live settings. In the end, the Mono/Poly strikes a solid balance between price and performance, earning a commendable score of eight or even nine out of ten.
