11: Dynamic Filter

• 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 (≥ Page 115), also available from the ELEMENT MODI-

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-m 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-m 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 (≥ Page

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-
