What Polysix does

The original Polysix was built as a six-voice polyphonic synthesizer, one voice more than the five-voice instruments common at the time, and it was named directly after that voice count. This plugin is the digitized version of that instrument, and it appears in the KORG Collection line based on the software Polysix emulation from 2004.

Settings such as 1VCO and the deep, fat polyphonic sound are part of that reproduction. The plugin is offered as VST3, VST2, AU and AAX for Windows and macOS, with native support for Apple Silicon listed.

Queries for the plugin name pair it with keygen and serial key, the repack is packed as .rar and .iso, and the VST3 and AU builds show up as VST crack and AU crack.

Key features

• Faithful Polysix circuitry. The plugin models the Polysix circuitry so the original sound and performance are reproduced, including the complex range of sounds the original instrument could produce.
• Two added multi-effects. Two new multi-effects were added compared with the earlier Polysix V2 in the KORG Collection.
• 300 new presets. The release includes 300 new presets alongside the original factory sounds.

Use cases

• Recreating Polysix sounds. Producers who want the sound of the 1981 six-voice instrument can use the CMT-based reproduction and the included presets as a starting point.
• Layering with effects. The chorus, phaser and ensemble effects, along with the two added multi-effects, can be used to spread a patch across the stereo image.

Compatibility

Polysix is offered as VST3, VST2, AU and AAX for Windows 10 and macOS 11 in 64-bit builds, with native Apple Silicon support listed.

Who it is for

The plugin suits producers and sound designers who want the sound and performance of the original six-voice Polysix, and who work in hosts that load VST3, VST2, AU or AAX builds.
