The Filter Envelope Depth is a dedicated modulation control. It sets the amount that the Filter Envelope controls the Cutoff frequency. At minimum setting, the Filter Envelope has no effect on the Cutoff. The higher the setting, the greater effect the Filter Envelope’s contour has on the Filter.

NOTE: If both the Filter Cutoff and Filter Envelope Depth are set to minimum values, little to no sound will be heard. If the Filter Cutoff is at the maximum value, then the ENV knob will have no effect, since the Cutoff is already wide open. A good starting point is to keep the ENV control at the middle point.

Range 0.000 to 1.000


This control inverts the Filter Envelopes contour and so it will have the effect of closing the filter (lowering the cutoff frequency). ENV will change to inverted text when tracking is inverted.
