Filter Envelope Controls

—Sets the attack time of the envelope. The higher the
Attack: 0...10
setting, the slower the attack time and the longer it takes for the filter to
open from the level set with the filter knob to the level set by the
cutoff
filter envelope amount. Percussive sounds typically have sharp (short)
attacks.
—Sets the decay time of the envelope. After a sound
Decay: 0...10
reaches the filter frequency set at its attack stage, controls how
decay
quickly the filter then transitions to the cutoff frequency set with the
knob. The higher the setting, the longer the decay. Percussive
sustain
sounds, such as synth bass, typically have shorter decays (and a generous
amount of filter resonance).
—Sets the filter cutoff frequency for the sustained portion
Sustain: 0...10
of the sound. The sound will stay at this filter frequency for as long as a
note is held on the keyboard.
—Sets the release time of the envelope. This controls
Release: 0...10
how quickly the filter closes after a note is released.
—Allows key velocity to influence filter
Velocity Switch: Filt, Amp
cutoff frequency and amplifier level (volume). When 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.
