9Depth knob: controlling the modulation depth applied by the envelope to the VCF cutoff frequency,
the larger the knob value the greater the depth.
Decay knob: controlling the amount of time of the envelope to decay from the current signal level to
the minimum level, the larger the knob value the longer the time.
Accent knob: adjusting the amount of Accent effect, the larger the value of the knob the more
obvious the Accent effect. (Only have an effect when notes programmed with an accent.)
Saturation switch: controlling the distortion effect.
Drive knob: controlling the level of distortion gain, the larger the value of the knob the greater the
gain.
Tone knob: controlling the brightness of the distortion tone, the larger the value of the knob the
brighter the tone.
Delay switch: controlling the delay effect.
Level knob: controlling the volume of the delay effect sound, the higher the value of the knob the
higher the volume of the effect sound.
Time knob: controlling the delay time of the delay effect, the larger the knob value the longer the
delay time.
Feedback knob: controlling the number of feedback of delay effect, the feedback number is 1 when
the knob value is minimum, the greater the knob value the greater the number of feedbacks.
Master knob: controlling the total output volume of the unit, the higher the value of the knob the
louder the volume.
