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.
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 CURVE (VELOCITY CURVE)
Select the curve of change with which the force of your
playing on the external MIDI keyboard will affect the
amount of change produced by the filter envelope.
Range: 1–7
F-ENV: VELO SENS (VELOCITY SENSE)
Specifies how the force of your playing on the external MIDI
keyboard will affect the filter envelope.
With positive (+) settings, the tone will change more as you
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 TIME1, 4 (VELOCITY SENSE TIME1,
4)
The strength with which a keyboard key on an external MIDI
keyboard pressed is used to control TIME 1, while the speed
at which the key is released is used to control TIME 4.
- VELO TIME 1
Range: -100– +100
With positive (+) settings, TIME1 will become faster as
you play the keyboard more strongly. With negative (-)
settings, TIME1 will become slower as you play the
keyboard more strongly.
- VELO TIME 4 (Amplifier Envelope Velocity TIME 4
Sensitivity)
Range: -100– +100
With positive (+) settings, releasing the keyboard more
quickly will cause TIME4 to be faster. With negative (-)
settings, releasing the keyboard more quickly will cause
TIME4 to be slower.

F-ENV: TIME KEY FOLLOW
This setting causes the filter envelope times (TIME 2/3/4) to
be affected by the location of the keyboard pad that you
press.
Relative to the envelope at the C4 note, higher settings of this
parameter will cause the times to change more greatly.
With positive (+) settings, times will become shorter as you
play higher notes. With negative (-) settings, times will
become longer as you play higher notes.
Range: -100– +100
In the following "F-ENV TIME 1-4" and "F-ENV LEVEL
1-4" screens, the TIME 1-4 and LEVEL 1-4 are indicated for
one tone, rather than for Tones 1, 2, 3, and 4. For example, if
before going to this screen the cursor is placed at TONE 2,
then the TIME 1-4 for TONE 2 is indicated.
F-ENV: TIME1–4
Specifies the time until the next cutoff frequency is reached.
You can make settings for the four parameters TIME 1–4.
Higher settings will lengthen the time until the next cutoff
frequency is reached.
Range: 0–127

F-ENV: LEVEL1–4
Specifies the cutoff frequency at each level. You can make
settings for the four parameters, Level 1–4.
Raising this setting will also raise the cutoff frequency.
Range: 0–127
For details on how TIME 1–4 and LEVEL1–4 of the envelope
correspond with the assignable knob parameters A, D, S, R,
