Filter Envelope Depth (-99 to +99) Page 7

The Filter Envelope is one of the most important sets of parameters in making a Program. Many Programs will use the Filter Envelope to determine the tonal character of the sound over time (attack, decay, sustain, and release). At +00, the filter envelope has no effect. Positive values raise the filter from the baseline cutoff frequency according to the envelope shape, and negative values similarly lower the cutoff frequency. The higher the number (negative or positive), the greater the effect. Filter Envelope parameters (such as attack and decay time) are programmed within the Filter Envelope Function (see page 133).

Note: This parameter interacts with several others. If you hear no change when you raise the Filter Envelope Depth, try lowering the Filter Frequency on the FILTER function's page 1 (push [PAGE] once to find it).
