Schwa oligarc, $60/$40

Schwa Oligarc, $60/$40

Coming from the makers of the intentionally cryptic Olga synthesiser, you'd expect Oligarc to be entirely over-the-top - and it is. Oligarc combines a filter and drive section with a chorus and a phaser and wraps 'em all around a kooky modulation section that converts the incoming audio signal into control signals that can drive the other effects.

Blue cat audio chorus

Blue Cat Audio Chorus, Free

Looking very much as if it were inspired by Eventide Clockworks' 1970s effects, this terrific freebie comes in a wide variety of plug-in formats and provides a terrific-sounding chorus with a reserved but flexible smattering of controls. A random mode generates presets if you're not inclined to set them up yourself, and both mono and stereo versions are included.
