The Yamaha CS1x is a sample-based synthesizer released by the Yamaha Corporation in 1996.

Aimed primarily at dance musicians[2], the CS1x features analogue synthesizer-emulating rotary controllers and monotimbral analogue synthesizer voices.[1]


The CS1x uses the Yamaha Sample and Synthesis technology, as well as General MIDI and XG voices from the MU-50 module.[1]

Effects and functions

The CS1x employs various arpeggiator presets and effects such as reverb, chorus (including flanging and celeste) and "variation" (a combination of reverbs, delays, modulation effects and equalisation).[1]

Notable users

The synthesizer has been used by Underworld, Jamiroquai, Skylab2000, Somatic Responses, Technological Sun, and David Bowie.[2]
