SOUND
The explanations here apply to step #3 on page 90.
■
FILTER
FILTER settings determine the overall timbre of the sound by boosting or cutting a
certain frequency range.
■
EG
The EG (Envelope Generator) settings determine how the level of the sound changes in time. This lets you reproduce
many sound characteristics of natural acoustic instruments — such as the quick attack and decay of percussion
sounds, or the long release of a sustained piano tone.
• ATTACK ...... Determines how quickly the sound reaches its maximum
level after the key is played. The higher the value, the
slower the attack.
• DECAY ........ Determines how quickly the sound reaches its sustain
level (a slightly lower level than maximum). The higher
the value, the slower the decay.
• RELEASE ..... Determines how quickly the sound decays to silence after
the key is released. The higher the value, the slower the release.

Determines the filter, EG, and
vibrato settings (see below).
In addition to making the
sound either brighter or
more mellow, Filter can be
used to produce electronic,
synthesizer-like effects.

Cutoff range
These frequencies are
“passed” by the filter.
• BRIGHTNESS
Determines the cutoff frequency or
effective frequency (resonance) range of
the filter (see diagram). Higher values
result in a brighter sound.
Resonance
• Harmonic Content
Determines the emphasis given to the
cutoff frequency, set in BRIGHTNESS
above (see diagram). Higher values result
in a more pronounced effect.
