YAMAHA QY70 Handy Sequencer with Built-in Tone Generator

YAMAHA Sequencer QY70 Yamaha
An XG mobile workstation boasting advanced sequencing capabilities and outstanding high-quality sound.
Features 4,167 built-in phrases and 768 patterns across various genres. This sound-module-equipped sequencer allows for easy music creation using accompaniment styles. Achieves a memory capacity of approximately 32,000 notes and a note resolution of 1/480. Its performance rivals professional sequencing software, enabling precise reproduction of subtle nuances. It has a total of 24 tracks: 16 sequencer tracks and 8 pattern tracks. Supports real-time and step input. Editing functions are also comprehensive, allowing for event editing per note. It's the smallest yet most powerful mobile workstation.

This is a considerably old product, so it shows signs of use commensurate with its age. However, it was not heavily used and was only used indoors. It was mostly stored away as I couldn't fully utilize its capabilities.

Comes as a set with the main unit and genuine AC adapter. No other accessories like the box are included.

Confirmed operations include: power on, cursor key operation, playback of sample songs using the PLAY button, sound production when all keyboard keys are pressed, and menu operations.

When powered off, a faint haze-like spot, about 5mm in size, is visible in the center of the LCD. This is barely noticeable when powered on and the screen is displayed. (Please check the last image.)
