This can be used to route the audio through both filters in series to produce
extreme filtering effects.
Each filter has its own Pan control. This is used to position the filter's output
signal within the stereo field. Note that Filter 1's pan control has no effect
when Filter 1 is routed to Filter 2.
A Balance control is also available. This is used to set the relative output
levels of Filter 1 and Filter 2. When set all the way to the right Filter 2
outputs with maximum volume while Filter 1 is muted. When set all the way
to the left Filter 1 outputs with maximum volume while Filter 2 is muted.
When set to an intermediate position both filters' output is in proportion to
the dial's position. When connecting both filters in series (that is, when you
route Filter 1 to Filter 2) this control should be set to the middle position.
The Vel (Velocity) control is used to set the degree to which the amplitude
is modulated by the note-on velocity of the MIDI input signal.
