"There are 6 knobs for envelope attack, release, filter cutoff, resonance and 2 are assignable knobs. Two scene memories will remember the current state of the envelope and filters as set by the control knobs so they can instantly be recalled and you can use the Mod-wheel to morph from one scene into the other.
Scene Memory data is also stored with your synth patches. Built-in digital effects are great.

The Arpeggiator steals the show with 30 patterns suited for all genres as well as basic arpeg. patterns.

Plenty of memory (128 preset, 128 user) and MIDI control make the CS1x perfect for both live and studio use. Control the synth, arpeggiator and editing through MIDI control. The CS1x only has multitimbrality in which, when hooked up to a sequencer, MIDI channels 5-16 offer Yamaha XG synth sounds but MIDI channel 1 holds the CS1x's main sounds and effects."
