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 pronounced electronic effects.

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 selected 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 frequency. Plus "+" values produce higher cutoff frequencies while minus "-" 70 VOICE EDIT MODE / 3:Filter
