The Eighty is a synthesizer inspired by the legendary CS-80, designed to deliver rich warmth and expressive sound. It incorporates three synthesis lines, including two that authentically recreate the linked high-pass and low-pass filters that defined the original instrument's distinctive tone. A third synthesis line can be seamlessly blended via an innovative 2D mixer, providing a broad palette of sonic possibilities for crafting unique sounds.

At its core, The Eighty meticulously models the oscillators and filters to capture the unique character of the CS-80, featuring resonant high-pass and low-pass filters that maintain warmth while avoiding digital artifacts. The carefully tuned resonance ensures smooth filter sweeps without distortion, even when frequencies align closely. Adding to its authenticity, the built-in Chorus effect enhances depth and movement, enriching the overall sound experience.

The Eighty offers extensive modulation options and an intuitive interface, making it ideal for sound designers, producers, and musicians seeking to create lush pads, soaring leads, or textured soundscapes. Its advanced 2D mixer, extended arpeggiator, and four high-quality effects — including delay, phaser, reverb, and EQ — combine for flexible sound shaping. Additional features such as ring modulation, vibrato, tremolo, and polyphonic aftertouch support provide dynamic control, while a robust preset manager streamlines finding the perfect sound for any musical project.
