What it is
The Eighty is a polyphonic subtractive synthesizer modeled on the Yamaha CS-80, one of the most expressive analog polysynths ever built. XILS-lab's design captures the CS-80's three-synthesis-line architecture, with linked high-pass and low-pass filters, zero-delay analog resonance, and a 2D mixer for real-time timbral blending. It's the same synth engine the CS-80 made famous on recordings from Vangelis, Keith Emerson, and others - rebuilt for modern production.
Who it's for
Producers making ambient, cinematic, synthwave, or progressive electronic music will get the most out of The Eighty. It suits anyone building dense layered pads, evolving textures, or expressive leads that need genuine analog warmth and dynamic range.
Key features
- Three synthesis lines with analog-modeled oscillators and filters reproduce the layered, orchestral character the CS-80 is known for
- Zero-delay 12 dB resonant high-pass and low-pass filters preserve warmth without digital harshness
- The 2D Mixer with animation allows real-time blending and morphing between synthesis lines for evolving, dynamic sounds
- An extended arpeggiator with per-step modulation control adds rhythmic movement and evolving patterns across the full sound
