NOTE: When increasing the resonance, depending on the sound, some very loud peaks
may be created as certain strong harmonics get boosted. This can result in distortion. To
reduce any distortion you may have, reduce the loudness control in the OUT pages.
The next three parameters down the right hand side are the modulation inputs to the
filter. The defaults for these are
respectively. These may be mixed and the range for each modulation input is the usual
+/-50. You will note that for there to be any effect, the
set to something lower than 99.

effects such as flute tremolando or drastic resonant synth effects whilst
used for shaping the tonal dynamics of the sound and restoring lost harmonic movement
due to looping. The multi-stages of ENV2 allow some interesting possibilities as we shall
see in a moment. The other options which you may select for modulating the filters are:

set to a high positive value, you may use velocity to control tone
This works much like pressure and moving the modwheel will cause the
filter cutoff to open and close. Use this for phrasing brass parts, perhaps,
or for special synth filter effects in a bass line or lead line.
This works like pressure and modwheel and allows you to open and close
the filter by moving the pitch bend wheel or lever. This can be effective
when bending up into a note as the filter will open and sound brighter.
This may be used for expressive swells, particularly on brass sounds.
This can select from footpedal, volume and breath for control of the filter
cutoff.
Although selectable as a mod source, it is not that worthwhile because this
is hardwired via the key follow parameter.
This allows you to emulate the natural tremolo of flutes, woodwind, brass
and other such instruments when set to small modulation amounts. When
set to large modulation amounts, classic synth filter sweeps can be
achieved. That LFO 1 can also be modulated leads to some very
interesting synth sounds and special effects.
On occasions, it is good to be able to have the filter's tonal dynamics
match those of the amplitudes. One easy way to achieve this is, instead of
copying the amplitude envelope to the filters envelope, simply assign the
amplitude envelope ENV1 to the filter.
This and the other "!" controllers allow you to control the opening and
closing of filter cutoff at the point of note on. They don't have any effect if
these controllers change through the course of the note but only when the
note is pressed.
