The Knobs - Assignable Parameters - Yamaha PSR-E473 Reference Manual

The Knobs — Assignable Parameters
This section describes the parameters which can be assigned to the Knobs.
z v
, CUTOFF / RESONANCE
These effects let you change the tone by controlling
which frequencies are filtered, and also by producing
a resonance peak at the cutoff frequency. Here, we'll
try creating some popular synthesizer filter effects.
NOTE
• When z is selected, these effects are applied to the Main and
Dual Voices.
When v is selected, these effects are applied to the Styles
and Grooves.
• Keep in mind that these effects can sometimes cause distor-
tion, especially in the bass frequencies.
 Knob A: CUTOFF
Changes the brightness of the sound by adjust-
ing the cutoff frequency. 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.
 Knob B: RESONANCE
Changes the emphasis of the cutoff frequency by
adjusting the amount of filter resonance. Turning
the knob to the right increases the Resonance to
emphasize the frequencies at the cutoff fre-
quency, resulting in an exaggerated peak.

Frequency
Frequencies in this
range are cut off.
Resonance
Frequency
x b
, 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 effects that make the sounds warmer
and more full. Turning the knob to the right
increases the Chorus depth.
NOTE
• When x is selected, these effects are applied to the
Main/Dual Voices. When b is selected, these effects are
applied to the Styles and Grooves.
c m
DSP1, DSP2
 Knob A/B: DSP PARAMETER A/B
With the built-in digital effects, you can apply
DSP effects to the sounds of this instrument. The
DSP1 effect is applied to the Main Voice, and the
DSP2 effect is applied to a part selected in
"DSP2 Part" (Function 043). Each effect has two
parameters which are assigned to Knobs A and
c
B. When is selected, you can control the
DSP1 parameters with the knobs. When
selected, you can control the DSP2 parameters.
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 distor-
tion.
