Sweep - Direction of the lter’s sweep. In the up position, the lter sweeps normally. In the down position, the sweep is reversed. You may need to change the settings of the gain and decay knobs; settings that work in the up position won’t always work well in the down position.
Peak - The “wetness” of the lter sound. Higher settings produce a more aggressive sweep with a sharper resonant peak.
Tone - The maximum cuto frequen- cy of the lter. It works like the tone knob of a guitar or bass. Higher set- tings will accentuate the treble fre- quencies; lower settings increase the lter’s warmth.
