This parameter can be modulated using the Mod Matrix (Fil / Env Depth).
The Vel (Velocity Tracking) can be used to modulate the filter frequency
with the Velocity (how hard a note is being played). Like with Track and Env
the dial can be used to gradually adjust the effect from fully reversed to
fully.
Much like in the Oscillator section the Filter section next offers the cross-
modulation settings, allowing audio rate modulation of
– Frequency (FM) and
– Resonance (RM)
The selector is above the amount dial.
The Dial itself sets the amount of Cross-Modulation which is also available
for modulation using the Mod Matrix (Fil / XMod Amt).
The source selector below each dial contains any of the four Oscillators
and any of the four filters. The output of the respective chosen source is
used as input for the cross-modulation.
Note: If an Oscillator which runs in Spread mode is chosen, still only one of
its voices is used for cross-modulation.
On of the right of the cross-modulation dials is the Volume dial allowing
adjustment of the filter output.
Each filter also has its own Pan (Panning or Panorama) dial. This is used to
position the filter's output signal within the stereo field.
Finally the balance of the filter output between two effects units can be
adjusted. The Balance gradually changes the amount of the signal going to
each of the selected effects units. You can for any filter choose any of the 6
effects units or the main output.
