3: FEG LEVEL & RATE
[VOICE] [EDIT] [MENU] 3:Filter [ENTER/YES] [ENTER/YES]
[MENU] 3:FEG Level&Rate [ENTER/YES]
The filter envelope generator is entirely separate from the amplitude EG, and is
used specifically to create time-based timbre variations. It can be used to simulate the
natural timbre variations produced by acoustic instruments, or to create more pro-
nounced electronic effects.
LVL/RATE (Level/Rate switch)
Range: LVL, RATE
Controls: [F1]
This “switch” determines whether the level parameters (L0 … L4, RL1, and
RL2) or the rate parameters (RS, R1 … R4, RR1, and RR2), described below,
are selected for editing.
L0 … L4, RL1, RL2 (Levels 0 … 4, Release levels 1 & 2)
Range: -63 ... +63
Controls: [CS2] [CS8], [-1] [+1], Dial
These parameters are available when the Level/Rate switch parameter is set
to “LVL”.
The level parameters work in conjunction with the rate parameters described
below to determine the “shape” of the cutoff envelope generator for the se-
lected filter. This function is only available if the “CTRL” parameter (page 68)
is set to “EG.”
The cutoff envelope generator level parameters correspond to cutoff fre-
quency. Plus “+” values produce higher cutoff frequencies while minus “-”
