PSR-I425 Owner’s Manual

Play with the right hand while operating Knob A with the
left hand.

If you select a different keyboard voice the knobs will be reset and the
ideal settings for the selected voice will be automatically recalled. In the
same way, if the “

v STYLE FILTER” effect is selected, the knobs will

be reset if a different style is selected. If you create an original setting
you like, it might be a good idea to save it in the instrument’s Registra-
tion Memory (page 80) so you can recall the same settings again at any
time. You can also record performances using original sounds you’ve
created (page 52).

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

Changing the knob settings does not immediately change the sound. Newly
assigned effects will only change the sound when the knobs are first
operated after the new effect has been selected.

Number/Effect

Try This

FILTER

Select a synth-type lead or pad voice (page 107). Turn Knob B all the way up and operate Knob A
while playing for some spacey, floating 1980’s effects.

EFFECT

Select a voice that sounds as though it already has reverb and chorus effects applied, and turn
Knob A and Knob B all the way down to hear the “direct” sound of the voice. You can then turn the
Knob A and Knob B settings up to add extra impact and richness to the voice.

Select a piano voice, and turn Knob B all the way up and Knob A to about the 3 o’clock position.
This should give you a majestic, organ-like sound. The attack time is quite long so play the keys
and hold them to let the sound come in fully. Ideal for slow pieces.

STYLE FILTER

Select style 31, Euro Trance. Turn accompaniment on and start style playback (page 34). Set
Knob B to about 3 o’clock, and Knob A to about 8 o’clock. The overall sound of the style should be
a bit muffled, with the drums emphasized for solid rhythmic impact.

STYLE TEMPO

Play a style and/or arpeggio (page 14) and use Knob A to adjust the tempo.
