Filter Edit Menu
To access the Filter Edit Menu press the filter button
shortly (if Auto Edit is set to on) or for some time (if Auto
Edit is set to off). Use the Selection dial to scroll through
the corresponding menu pages. The name of the page is
shown in the top of the display. The Filter Edit menu is
located before the Filter Envelope Edit menu and behind
the Oscillator Edit menu.
Filter 1 and 2
The following parameters refer to the selected filter. This
is shown in the upper display area.
Keytrack -200%...+196%
Determines how much the cutoff frequency depends on
the MIDI note number. The reference note for Keytrack is
E3, note number 64. For positive settings, the cutoff
frequency rises on notes above the reference note, for
negative settings the cutoff frequency falls by the same
amount, and vice versa. A setting of +100% corresponds
to a 1:1 scale, so e.g. when an octave is played on a
keyboard the cutoff frequency changes by the same
amount. If you want to play the filter in a tempered scale,
e.g. for a solo sound with self-oscillation, set the value to
+100%. On most bass sounds lower settings in the range
+50…+75% are optimal to keep the sound smooth at
higher notes.
Env Velocity -64...+63
Determines the amount of influence the filter envelope
has on the cutoff frequency, based on key velocity. This
parameter works similarly to the Env parameter with the
difference that its intensity is velocity based. Use this
feature to give a more expressive character to the sound.
When you hit the keys smoothly, only minimal
modulation is applied. When you hit them harder, the
modulation amount also gets stronger.

The overall modulation applied to the filter’s cutoff
frequency is calculated as the sum of both the Env
Amount
and Env Velocity parameters. Therefore
you should always bear this total in mind, especially
when the filter does not behave as you expect. You
can also create interesting effects by setting one
parameter to a positive and the other to a negative
amount.
