description
The growing demand for all-in-one solutions in the mid-1990s prompted Yamaha to expand its QY series with the QY70. This included a 32-part tone generation with 519 normal sounds (XG format) and 20 percussion sets of 128 sounds. 128 presets were already pre-programmed and 64 were available to the user for free programming. Two multifunctional piano octaves (25 mini buttons, not velocity-sensitive) serve as the main control unit, as they were already built into devices such as the Roland TB-303.
The device was also provided with a MIDI interface for commands in and out of the workstation (no MIDI thru) and the AWM2 method was used as the sound generation method. Three effect units could be used with the 16 existing tracks and processed with the sounds from the 4 MB memory.
Despite not being very successful, the instrument found a successor in 2001 with the QY100. A larger MIDI sequencer called the QY700 was also available.
The device could be operated with both a power supply unit and a battery.
