Parameters Assigned to the Knobs This section describes each of the parameters which can be assigned to the Knobs (page 24). z RIYAZ BALANCE Knob A adjusts the volume balance between the sounds Level of Tabla 1 and 2, while Knob B adjusts the volume bal- ance between the sounds of Tabla and Tanpura. Resonance x RIYAZ TEMPO/RIYAZ KEY Knob A adjusts the tempo of Tabla playback while the Tanpura playback tempo is maintained. This follows typical Indian music stylistic conventions. Knob B raises or lowers the pitch of the Riyaz sound in semitones, with the exception of Tabla 1. This accurately simulates the characteristics of the Tabla, in which the lower sound is not affected by the tuning. Note that also the pitch of Tabla 2 may not be changed depending on the Riyaz pattern. NOTE • When Knob B is turned all the way left, only the pitch of the Tabla 2 sound is raised abruptly by an octave. This is due to a limitation in this instrument. c CUTOFF/RESONANCE These effects shape the sound by allowing only a specified range of frequencies to pass and/or by producing a resonance peak at the "cutoff" frequency. These effects can be used to create a range of synthesizer-like sounds. NOTE • When the target is KEYBOARD, these effects are applied to the Main/Dual Voices. When the target is BACKING, these effects are applied to the Styles and Riyaz patterns. • These effects can sometimes cause distortion, especially in the bass frequencies.  Knob A: CUTOFF Adjusts the 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 Frequency v REVERB/CHORUS  Knob A: REVERB Reproduces the acoustic ambience of a concert hall or club. Turning the knob to the right increases the Reverb depth.  Knob B: CHORUS Produces a rich and warm layered effect. Turning the knob to the right increases the Chorus depth. NOTE • When the target is KEYBOARD, these effects are applied to the Main/Dual Voices. When the target is BACKING, these effects are applied to the Styles and Riyaz patterns. b DSP  Knob A/B: DSP PARAMETER A/B With the digital effects built into the instrument, you can add DSP effects to your keyboard performance and the playback sound of Styles, etc. (page 23). Each effect has two parameters which are assigned to Knobs A and B. By turning the knobs in real-time, you can alter the music in various dynamic ways, such as changing the rotating speed (slow/fast) of the rotary speaker or changing the degree of the Distortion. n ATTACK/RELEASE These 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. 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 cutoff frequency. Turning the knob to the right increases the Resonance to emphasize the frequencies at the cutoff frequency, resulting in an exaggerated peak.
