Among their more terrestrial pursuits are musical instruments, which range from keyboards to drum machines to MIDI controller guitars. Always at the forefront of emerging technologies, their synthesizer division has on numerous occasions beaten the world's top synthesizer developers to the punch in bringing groundbreaking technologies to market. In addition to their professional synthesizer market, Casio has a portable keyboard division that consistently produces high-value auto-accompaniment keyboards for the consumer market. They are a quality manufacturer that always stresses features relative to price and unerringly remains at the forefront of emerging keyboard technologies.
