Parameters Assigned to the Knobs This section describes each of the parameters which can be assigned to the Knobs (page 21). z FILTER Filter effects shape the 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 synthesizerlike sounds. NOTE • These effects are applied only to the Main/Dual Voices played on the keyboard. • Filter effects can sometimes cause distortion in the bass fre- quencies.  Knob A: CUTOFF Adjusts the filter's cutoff frequency, and therefore the brightness of the sound. Turning the Knob to the left makes the sound more muffled or darker, while turning the Knob A to the right makes the sound brighter. Level Cutoff Frequency Frequencies in this range are passed. Frequency Frequencies in this range are cut off.  Knob B: RESONANCE Adjusts the amount of Resonance applied at the filter's cutoff frequency. Turning the Knob to the right will increases the Resonance to emphasize the frequencies at the cutoff frequency, and thus "strengthens" the perceived effect of the filter. Level Resonance c EG (Envelope Generator) Envelope Generator effects determine how the level of the sound varies over time. You can make the attack faster for a more percussive sound or slower for a violin-like sound, for example. Or you can lengthen or shorten the sustain to best match the music you're playing. Level Sustain Level ATTACK DECAY RELEASE Time Key Played Key Released  Knob A: ATTACK Adjusts the Attack Time (the amount of time it takes the sound to reach maximum level when a key is played). Turning the Knob to the right will increase the Attack Time, thus slowing down the attack rate.  Knob B: RELEASE Adjusts the Release Time (the amount of time it takes for the sound to decay to silence after a key is released). Turning the Knob to the right will increase the Release Time, thus make a longer sustain. NOTE • These effects are applied only to the Main/Dual Voices played on the keyboard. v STYLE FILTER Same as " z FILTER." These effects are applied only to Style or Pattern playback. Frequency x EFFECT  Knob A: REVERB Reproduces the acoustic ambience of a concert hall or club. Turning the Knob to the right will increase the Reverb depth.  Knob B: CHORUS Produces a layered "multi-instrument" effect. Turning the Knob to the right will increase the Chorus depth. NOTE • These effects are applied only to the Main/Dual Voices played on the keyboard. b SOUND IMAGE  Knob A: PAN Moves the stereo pan position of the entire sound rightward or leftward according to the Knob position.  Knob B: ULTRA-WIDE STEREO Lets you play the keyboard with a spacious, dynamic sound effect that gives you the sensation of hearing the sound outside of the speakers. By changing the wide effect type in the Function settings (page 49), you can enjoy different sound variations. PSR-E433 Owner's Manual 37 Reference
