CS-80 — Yamaha

Descripción

The Yamaha CS-80 is an analog polyphonic keyboard in the category of claviers synthétiseurs analogiques. It is described as a heavy, high-quality weighted keyboard with aftertouch and velocity sensitivity, and it offers portamento and glissando as performance features. Key characteristics highlighted in user reports include eight-voice polyphony and bi-timbral operation, with a dual serial filter section (high-pass and low-pass) and a dedicated envelope with five parameters. The sound is noted for its expressiveness and distinctive character, aided by modulation options such as a sub-oscillator that can be controlled via aftertouch or directly, and a chorus or ring-modulator effect. Typical use cases presented emphasize real-time, expressive playability and dynamic control, useful for complex, brass-like or vivid synthetic timbres. However, the machine is described as demanding to operate, with a substantial physical footprint and a reputation for maintenance challenges due to its analog, non-digital internals. Presets and editable factory tones are mentioned, alongside the model’s status as a rare, highly sought instrument.
