01(01): CutoffFreq

•Cutoff Frequency

•Settings: -64 … +63

03(03): FilEG Dept

•Filter EG Depth

•Settings: -64 … +63

The “FilEG Dept” parameter determines to what degree the amplitude /filter envelope generator (see “08(06): Attack Time”, “09(07): Decay Time”, and “10(08): ReleaseTime”, below) affects the filter’s cutoff frequency. Higher values allow the envelope generator to vary the filter cutoff frequency over a wider range.

04:CutoffScBP (VOICE mode only)

• Cutoff Scaling Breakpoint

• Settings: C-2 … G8

Sets the cutoff frequency of the VL70-m filter.

02(02): Resonance

•Resonance

•Settings: -64 … +63

This parameter produces a resonant peak at the filter’s cutoff frequency, thereby emphasizing frequency components at that frequency. When “Resoance” is set to its minimum value, the filter response rolls off sharply at the cutoff point. As the resonance value is increased, however, a peak of correspondingly increasing amplitude is produced at the cutoff frequency.

Filter cutoff frequency “scaling” ( or “key scal- ing”) produces natural timbre variations across the VL70-m note range by allowing an increasing or decreasing filter “depth” curve to be applied above or below a specified “breakpoint” note. The “CutoffScBP” parameter specifies the breakpoint note.

05:CutoffScDpt (VOICE mode only)

• Cutoff Scaling Depth

• Settings: -64 … +63

This parameter specifies the amount of filter cutoff frequency key scaling to be applied above or below
