The Casio Casiotone CT-S1 is a slim 61-key portable keyboard focused on curated AiX piano, EP, and organ tones (61 tones, 64-note polyphony) with a simple control layout and bass-reflex speakers. Stand and bench are sold separately unless your SKU includes them. Sound and Touch AiX sound focuses on curated piano, electric piano, and organ tones instead of a huge GM list, so the CT-S1 stays simple to play. Full-size touch-responsive keys and bass-reflex speakers keep the feel and tone usable for living-room practice and small gigs.
