Yamaha CS 15

The Yamaha CS-15 is a analog synthesizer produced by Yamaha from 1978 to 1982. It features two voltage-controlled oscillators and a multi mode filter.

Though the CS-15 is not as well as known as contemporary Yamaha synths such as the CS-80, it was used by several bands in the early 1980s. The Human League made prominent use of the instrument on their album Dare. Marillion used a CS-15 on their first full-length album, Script for a Jester's Tear.
