5. The tone generator block

About the tone generator block

• The tone generator block is what actually produces sound
in response to the MIDI messages received from the
sequencer block, the controller block, and from the MIDI
IN connectors.
• The tone generator block always functions as a 32 part multi-
timbral tone generator.
• The tone generator block of the QY700 is GM and XG com-
patible. It is able to playback any song data bearing the GM
logo or XG logo, including extension voices and effect set-
tings.

Voices

• “Voices” are the individual sound programs that you can
edit, which are used by the tone generator to produce sound.
• There are two types of voices: normal voices which change
their pitch as you play different notes on the keyboard, and
drum voices which produce a different rhythm instrument
sound for each note of the keyboard.
• Normal voices consist of 1 or 2 “elements.” By using two
elements you can produce a richer sound, or create a voice
that produces different sounds depending on the pitch or
velocity.
• Drum voices are special voices in which different sounds
are assigned to each note. You can make detailed modifica-
tions to the sound of each note.
• Elements are the building blocks that each voice is made
of, and are made from sampled waveforms. You can make
detailed modifications to the pitch, tone and volume.

Voice Category, Program Number, and Bank

Number

• The QY700 contains 480 normal voices and 11 drum voices.
This is more voices than can be selected by a program
number of 1 – 128. Thus, voices are selected on the QY700
using a combination of the Voice Category, Program
Number, and Bank Number.

Voice Category

• The Voice Category is a broad classification of the type of
voice. The QY700 uses four voice categories: normal voices
, SFX voices , SFX kits and drum voices .
In addition to these four voice categories, you can select
drum setup 1 and drum setup 2 in Voice mode, and
drum setup 3 in Pattern mode. These three categories
are used to select drum setups, and are used in a different
way than the first four categories.
• Normal voice is the voice category that specifies nor-
mal voices.
• SFX voice is a voice category that specifies sound ef-
fects. The sound effects in this category have the same ele-
ment structure as normal voices, and their pitch will change
as different notes of the keyboard are played.
• SFX kit is a voice category that specifies sound effect.
The sound effects in this category have the same element
structure as drum voices, and will produce different types
of sound effect as different notes of the keyboard are played.
