F1/2 Vel Freq (Filter 1/2 Velocity Frequency)
Sets the velocity sensitivity for the cutoff frequency
parameter. When F1/2 Vel Freq is set to a positive
value, the harder a note is played on the keyboard,
the higher the cutoff frequency becomes, and a
greater change occurs in the timbre of the sound.
Negative values will have the opposite effect.
Settings: –7~+7
F1/2 Vel Gain (Filter 1/2 Velocity Gain)
Sets the velocity sensitivity for the gain level. When
F1/2 Vel Gain is set to a positive value, the harder a
note is played on the keyboard, the more the amount
of gain is applied. Negative values will have the
opposite effect.
Settings: –7~+7
F1/2 Freq EG Depth (Filter 1/2 Frequency EG
Depth)
Sets the depth of the change in the cutoff frequency
over time. The higher the value, the wider the
change in depth becomes. Negative values will result
in an inverted envelope.
Settings: –64~0~+63
F1/2 Freq Random (Filter 1/2 Frequency
Random)
Freq Random causes the cutoff frequency to move
randomly. The higher the value, the greater the
change in the movement. A setting of “0” produces
no effect.
Settings: 0~15
F1/2 Freq KeyFlw (Filter 1/2 Frequency
KeyFollow)
Sets the KeyFollow for the cutoff frequency. The
F1/2 Freq KeyFollow adjusts the cutoff frequency by
the notes played on the keyboard. When the F1/2
Freq KeyFollow is set to a positive value, the larger
the note played on the keyboard, the higher the
cutoff frequency becomes. When a negative value is
set, the lower the note played, the higher the cutoff
frequency becomes.
Settings: –64~+63
[F7]: SCALE
Sets the scaling for the filter. The filter scaling function
adjusts the filter cutoff frequency based on notes played
on the keyboard. There are four Break Points, each
with their own offset level settings. A different value
can be set for the two DCF filters of each element.
Press [F2] and [F3] to select the DCF1 and the DCF2
screens, respectively.
BP 1~4 point
BP 1~4 Level
Settings:
BP 1/2/3/4 Point: C–2~G8
BP 1/2/3/4 Level: –128~+127
Setting the Filter Scaling
Set the note names (pitch) and the offset levels for
each break point (BP1-4) as seen in the following
example.
In this example, with a cutoff frequency of 64, the
note name E1 at the BP 1 Point is set to the offset
value –4. B2 at the BP 2 Point is +10. G4 at the BP
3 Point is +17. And A5 at the BP 4 Point is +4.
Each cutoff frequency will be offset to 60, 74, 81
and 68, respectively. The cutoff frequencies other
than the ones at each Break Point will be on the
straight line connected between the two adjacent
Break Points.
Sets the Break Point note names from the lowest
BP1 to the highest BP4. Be aware that, for example,
the BP1 note name cannot be set higher than the
adjacent BP2.
The Break Point level is an offset value and will
increase or decrease from the currently selected
cutoff frequency. Even if an offset value is set above
or below the limits of the cutoff frequency, it will
not go beyond the upper and lower cutoff frequency
limits.
A note set below the BP1 Break Point becomes the
BP1 level. Likewise, a note set above the BP4 Break
Point becomes the BP4 level.
