Features

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

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]

Sequencer

The Yamaha CS1x can be expanded with a small sequencer workstation module. The CS1x, CS2x and AN1x synthesizers all have a small lip on the right hand end of the front panel to accommodate a QY or SU sized module.
