26 About the Filter Envelope Sequential
9. The Filter Envelope’s
release
parameter acts in conjunction with the
Amplifier Envelope (Envelope 2 by default), so to hear its effect, first
set the Amp Envelope’s
release
value to a 1 o’clock position.
10. Now repeatedly strike a note on the keyboard as you turn the Filter
Envelope’s
release
knob clockwise and counterclockwise. Notice how
the note fades out faster or slower as you change the
release
value.
11. Continue experimenting with various Filter Envelope settings while
you adjust Envelope 1’s
amount
knob. Notice how greater
amount
settings amplify the effect of the envelope on the filter.
As noted above, the Filter Envelope and Amplifier Envelope often work
in conjunction, with the Filter Envelope controlling how the filter opens
and closes and the Amplifier Envelope controlling how the Amplifier
controls the overall volume shape of the sounds you create. To learn
more about the Amplifier Envelope, see “About the Amp Envelope” on
page 27.
Envelope Parameters
Attack: Sets the attack time of the envelope. The higher the setting, the
slower the attack time and the longer it takes for the filter to open from
the level set with the filter
cutoff
knob to the level set by the filter enve-
lope amount. Percussive sounds typically have sharp (short) attacks.
Decay: Sets the decay time of the envelope. After a sound reaches the
filter frequency set at its attack stage,
decay
controls how quickly the
filter then transitions to the cutoff frequency set with the
sustain
knob.
The higher the setting, the longer the decay. Percussive sounds, such as
synth bass, typically have shorter decays (and a generous amount of low-
pass filter resonance).
Sustain: Sets the filter cutoff frequency for the sustained portion of the
sound. The sound will stay at this filter frequency for as long as a note is
held on the keyboard.
Release: Sets the release time of the envelope. This controls how
quickly the filter closes after a note is released.
Velocity On/Off: On, Off —Allows key velocity to influence filter cutoff
frequency. If on, the harder you play, the more the filter will open and the
brighter the sound will be. If off, key velocity will not affect the filter.
This control allows for more touch-sensitive sounds.
