z Filter Filter effects shape sound by allowing only a specified range of frequencies to pass and/or by producing a resonance peak at the filter's "cutoff" frequency. Filter effects can be used to create a range of synthesizer-like sounds. * Filter effects can sometimes cause distortion in the bass frequencies. Some hints for using the filter effects are provided on page 22. Filter Cutoff Filter Resonance Create Original Sounds Knob A adjusts the filter's cutoff frequency, and therefore the brightness of the sound. Level Cutoff Frequency Frequencies in this range are passed. Frequency Frequencies in this range are cut off. Knob B adjusts the amount of resonance applied at the filter's cutoff frequency. Increasing the resonance emphasizes the frequencies at the cutoff frequency, and thus "strengthens" the perceived effect of the filter. Level Resonance Frequency x Effect Reverb reproduces the acoustic ambience of a concert hall or club, while chorus produces a layered "multi-instrument" effect. Reverb Chorus Send Level Send Level Knob A adjusts the depth of the reverb effect, and Knob B adjusts the depth of the chorus effect. PSR-E413 Owner's Manual 19
