FILTER: RESONANCE
Adding a Distinctive Character to the Sound (Resonance)
This setting emphasizes the overtones in the region of the
cutoff frequency, adding character to the sound.

RESONANCE=0 RESONANCE=64
Range: 0–127
As the value is increased, the sound will take on more
character. As the value is decreased, the sound will be more
natural.
In order to prevent the resonance from being increased
excessively, factory settings have been made so that the value
will not rise beyond "110" even if the [RESONANCE] knob is
rotated all the way to the right. This is called the Resonance
Limiter. You are free to adjust this upper limit.
(refer to Defining the variable range for resonance
(RESONANCE LIMITER) (p. 115).)
If you have increased the Resonance Limiter setting, be careful
not to raise the resonance excessively. Excessively high values
may cause sounds to be distorted or the volume level to become
unexpectedly high.
Some settings may damage your hearing, or your speakers.
Please use caution.
FILTER: RES VELO SENS (RESONANCE VELOCITY
SENSE)
Specifies how resonance depth will be affected by your
playing velocity.
With positive (+) settings, playing the keyboard more
strongly will cause the change to be greater. With negative (-)
settings, playing the keyboard more strongly will cause the
change to be less.
Range: -100– +150
F-ENV (FILTER ENVELOPE) parameters
F-ENV: ENV DEPTH (ENVELOPE DEPTH)
This setting adjusts the depth of the filter envelope.
As the value is increased in the positive (+) direction, the
amount of tonal change will increase. With negative (-)
settings, the shape of the envelope will be inverted, and the
tone will change in the opposite direction.
Frequency
When setting Envelope Depth to a positive (+) value, the
effect of the filter envelope will be easier to hear if you set a
lower cutoff frequency.
Range: -63– +63
F-ENV: VELO SENS (VELOCITY SENSE)
Specifies how the force of your playing velocity will affect
the filter envelope.
With positive (+) settings, the tone will change more as you
RESONANCE=127
play more strongly on the keyboard. With negative (-)
settings, the tone will change less as you play more strongly
on the keyboard.
With positive (+) settings of TIME, the sound will be brighter
for strongly-played notes, and darker for softly-played notes.
Range: -100– +150
F-ENV: VELO TIME SENS (VELOCITY TIME
SENSE)
This parameter lets your playing dynamics on the external
MIDI keyboard control the overall time of the entire
envelope.
With positive (+) settings, envelope times will become faster
as you play the keyboard more strongly. With negative (-)
settings, envelope times will become slower as you play the
keyboard more strongly.
Range: -100– +100
F-ENV: TIME1–4 (ENVELOPE TIME1–4)
Specifies the time until the next cutoff frequency is reached.
You can make settings for the four parameters TIME 1–4.
Raising this setting will also raise the cutoff frequency.
Range: 0–127
