Parameters Assigned to the Knobs  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 increases 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 increases the Release Time, thus making a longer sustain. NOTE • These effects are applied only to KEYBOARD. The target cannot be switched to BACKING. The chart below lists some interesting ways to use the various effects that can be assigned to the knobs. Some Ideas for Using the Knobs Number/Effect Try This z RIYAZ BALANCE Knob A adjusts the volume balance between the sounds of Tabla 1 (having the lower sound) and Tabla 2 (having the higher sound of Tabla or Mridangam). Knob B adjusts the volume balance between the sounds of the Tabla (assigned to the [TABLA 1] and [TABLA 2] buttons) and Tanpura (assigned to the [TANPURA 1]-[TANPURA 4] buttons). Play with these Knobs as the patterns loop, sing along if you wish, and create your own performance. x RIYAZ TEMPO/RIYAZ KEY Knob A adjusts the tempo of Riyaz playback. Setting to the minimum left-most position results in half the default tempo, while setting to the maximum right-most position results in double the default tempo. The center position corresponds to the default tempo. Note that the tempo cannot exceed the range (11-280), and that the tempo of the Tanpura patterns will not change even if you rotate Knob A. Knob B raises or lowers the pitch of the Riyaz sound in semitones. Regarding the Tabla, only the higher sound (assigned to the [2] button) will be transposed. Rotating the knob leftward lowers the pitch while rotating the knob rightward raises the pitch. NOTE • The pitch of Tabla 2 may not be changed depending on the Riyaz pattern. Use these knobs to set the desired tempo and key, sing along if you wish, and create your own performance! Select "183 Gemini" (a synth-lead type Voice) or "210 Noise". Select c with [KNOB c CUTOFF/RESONANCE ASSIGN] button, and then switch the target to KEYBOARD. Turning Knobs A or B while playing gives you the dynamic filter-sweep effects of an analog synthesizer. v REVERB/CHORUS Select the Voice "048 CP80." Select v with [KNOB ASSIGN] button, and then switch the target to KEYBOARD. Turn Knobs A and B all the way down to hear the direct, unprocessed sound of the Voice. As you turn Knob B toward the right, a Chorus effect with modulation is gradually applied to the sound. Turning Knob A to the right adds a Reverb effect that makes you sound like you are playing in a concert hall. b DSP Select the Voice, "059 Cool!Org." Select b with [KNOB ASSIGN] button, and then switch the target to KEYBOARD. Press the [DSP] button to turn the DSP on, then set the DSP type (Function 042) to "01 RotarySp." Use Knob A to change the rotating speed of the rotary speaker while playing the keyboard. When you move it slowly, you can create gradual speed changes like on a real rotary speaker. Use Knob B to control the distortion. n ATTACK/RELEASE Select the Voice "213 RSAnPad." Turning Knob A all the way down makes the attack faster, and lets you hear the crisp, clear sound of the original Voice. Turning Knob B all the way down shortens the amount of time for the sound to decay to silence after a key is released. These knobs let you finely adjust the Voice to create the appropriate sound for the particular song you're playing. 58 PSR-I500 Owner's Manual Reference
