The § and ¶ buttons ("Bpag" and "Fpag") can be used to go directly
•
backward or forward to the next Element Controller page without having to
return to the directory.
The • button ("Para") can be used to go directly to the Dynamic Filter
•
parameter page (≥
FIER directory. You can then return to the controller Dynamic Filter page by
pressing • ("Ctrl") again.
Controller
≤
off, Modulation Wheel ... Touch EG (124 settings).
The VL1 dynamic filter has selectable high-pass, bandpass, band elimnination, and
low-pass modes. The "Controller" parameter specifies the controller to be used for
filter cutoff frequency control. When set to "off" no filter frequency variation can be
applied via a controller.
• The actual dynamic filter frequency value applied to the VL1 tone generator is
a mix of the value from the controller, the value from the Dynamic Filter
parameter page, and that from the amplitude & filter envelope (≥
143).
Depth
≤
-127 ... 127.
Sets the amount of variation produced by the controller assigned to dynamic filter.
The higher the value the greater the variation. Positive values cause an increase in filter
cutoff frequency in response to higher controller values (e.g. increased breath pressure or
higher modulation wheel position), while minus values cause a decrease in filter cutoff
frequency in response to higher controller values. The "Depth" setting is reflected in the
graph to the right of the parameters — the horizontal axis represents the controller value
and the vertical axis represents filter cutoff frequency.
Curve
≤
-16 ... 16.
Determines the relationship between the controller value and dynamic filter cutoff
frequency. When set to "0" the relationship is linear. That is, a change in the controller
value produces a corresponding change in frequency. As the curve value increases the
lower end of the controller range has relatively little effect on the sound while higher
controller values produce more dramatic changes. Negative curve values have the oppo-
