Overview
The Yamaha QY10, released in 1990, was the world's first handheld music sequencer. This battery-powered device offered 8-track sequencing, 28 voices of FM synthesis, and a built-in speaker in a portable package that fit in a pocket.
The QY10 allowed musicians to compose complete arrangements anywhere. The compact QWERTY keyboard and LCD display facilitated note entry and editing. The internal FM sounds were limited but sufficient for sketching ideas.
The QY10 pioneered portable music production, predating smartphones and tablets by decades. It remains a collectible curiosity for its innovative form factor.
