Voices & Effects
The QY70’s internal tone generator, compatible with XG and GM
format, provides 519 top-quality voices plus 20 complete drum kits with
different drum and percussion instruments assigned to different notes. You
can assign any of these voices to the sequencer tracks and patterns, or
play them from an external keyboard or other MIDI controller via the MIDI
interface, or directly from a personal computer. The QY70 also features a
high-quality internal DSP (Digital Signal Processor) system which provides a
range of reverb, delay, modulation, distortion and other effects in three
individually programmable groups so you can produce a polished sound
without the need for external equipment.
■ DETAIL
• See the List Book for a complete list of the QY70 voices.
• The QY70 effects are described on page 212.
GM(General MIDI) System Level 1
“GM System Level 1” is a standard specification that defines
the arrangement of voices in a tone generator and its MIDI
functionality, ensuring that data can be played back with
substantially the same sounds on any GM-compatible tone generator,
regardless of its manufacturer or model.
Tone generators and song data that meet the “GM System Level 1” bear
this GM logo.
XG
“XG” is a tone generator format that expands the voice
arrangement of the “GM System Level 1” specification to
meet the ever-increasing demands of today’s computer
peripheral environment, providing richer expressive power while maintaining
upward compatibility of data. “XG” greatly expands “GM System Level 1”
by defining the ways in which voices are expanded or edited and structure
and type of effects.
When commercially available song data bearing the XG logo is played back
on a tone generator which bears the XG logo, you will enjoy a full musical
experience that includes unlimited expansion voices and effect functions.
