Description
Adjusts the modulation rate, or speed, of the LFO.
Delay Time (LFO Delay Time) specifies the time elapsed before the LFO effect is applied (the ef-
fect continues) after the key is pressed (or released).
Specifies the time over which the LFO amplitude will reach the maximum.
Selects the waveform of the LFO.
SINE: Sine wave
TRI: Triangle wave
SAW: Sawtooth wave
SQR: Square wave
RND: Random wave
TAP: Trapezoidal wave
S&H: Sample & Hold wave (one time per cycle, LFO value is changed)
CHAOS: Chaos wave
This specifies whether the LFO cycle will be synchronized to begin when the key is pressed (ON)
or not (OFF).
Amount of LFO applied to filter cutoff frequency
Amount of LFO applied to resonance
Description
Specifies the depth of the envelope. Higher settings will cause the envelope to produce greater
change. Negative (-) settings will invert the shape of the envelope.
Specifies the attack time of the envelope (the time from when you press a key until the envelope level
reaches the maximum value).
Specifies the decay time of the envelope (the time from when the envelope level reaches the maxi-
mum value until it falls to a constant value).
Specifies the sustain level of the envelope (the level at which the envelope remains constant).
Specifies the release time of the envelope (the time from when you release a key until the envelope
level reaches 0).
Set this when you want the amount of the envelope to change depending on the force with which you
press the keys. Set this to a positive (+) value to have the changes in envelope amount increase the
more forcefully the keys are played; to make the envelope play more softly as you play harder, set
this to a negative (-) value.
