Envelope Filter (EF)The Envelope Filter effect is an amplitude modulated filter. As the input signal level to the envelope filterchanges, the filter frequency changes. This effect is sometimes referred to as an “automatic wah.”ParametersThe Sn (Sensitivity) parameter is used to adjust the sensitivity to changing input signal levels. Rangeis k100. If the sensitivity is set to a positive number, then the filter frequency will increase witha rising input. If sensitivity is negative, then frequency decreases with a rising input level.The Fq (Frequency) parameter adjusts the starting point of the filter frequency. Kange is O-100.From there the filter will sweep up or down (depending on sensitivity) as the playing level changesfrequency ranging from 2K to SK, respectively. When the sensitivity is positive, the frequencyvalues correspond to the frequency range 100 Hz to 2 kHz.When the Bandpass filter type is selected, the KS (Resonance) parameter is used to adjust theamount of the Bandpass filter. Kange is 0 (narrowest) to 100 (widest). When the Lowpass filteris selected, Resonance adjusts the steepness of the filter cutoff.The Ty (Type) parameter is used to select the filter type. Select LP-Slo (lowpass-slow), LP-Fst(lowpass-fast), BP-Slo (bandpass-slow), or BP-F& (bandpass-fast).The Mx (Mix) parameter is used to control the direct/effect mix at the output of the effect.Range is 0400%.Auto Pan (PN]The Auto Pan effect is used to pan the output signal between the left and right outputs. The panning rateand depth are both user selectable. The Auto Pan is a stereo effect.ParametersRt.Up:The Rt (Kate) parameter selects the speed at which the signal pans between the two outputs.Kange is O.O-99.9Hz.The Dp (Depth) parameter determines the amount of signal being panned. Kange is O-100%.Selecting a depth setting of 10% would yield a less clefined pan, and setting the depth to 90%would result in a deep panning from side to side.A-14 Appendix A individual Effects
