Filter Envelope Controls
Attack: 0...10—Sets the attack time of the envelope. The higher the
setting, the slower the attack time and the longer it takes for the lter to
open from the level set with the lter cutoff knob to the level set by the
lter envelope amount. Percussive sounds typically have sharp (short)
attacks.
Decay: 0...10—Sets the decay time of the envelope. After a sound
reaches the lter frequency set at its attack stage, decay controls how
quickly the lter 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 lter resonance).
Sustain: 0...10—Sets the lter cutoff frequency for the sustained portion
of the sound. The sound will stay at this lter frequency for as long as a
note is held on the keyboard.
Release: 0...10—Sets the release time of the envelope. This controls
how quickly the lter closes after a note is released.
Velocity Switch: Filt, Amp—Allows key velocity to inuence lter
cutoff frequency and amplier level (volume). When on, the harder you
play, the more the lter will open and the brighter the sound will be. If
off, key velocity will not affect the lter. This control allows for more
touch-sensitive sounds.
