SA Series Keyboard
The SA series electronic keyboard is a product line of children's toy electronic keyboards under Casio. This type of product uses mid-size keyboards with 25, 37 or 49 keys.
Most SA series products do not have automatic accompaniment, but some models have drum beats and rhythms with melody.
SA series products used OKI series sound source solutions in the early days, and later switched to Holtek solutions.
