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 , and

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 parameter should be

set to something lower than 99.

With set to a high positive value, you may use velocity to control tone

colour much like you would find on an acoustic instrument with louder notes yielding

brighter sounds and, of course, vice versa. may be used for filter sweep

effects such as flute tremolando or drastic resonant synth effects whilst is

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:

Modwheel 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.

Bend 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.

Pressure This may be used for expressive swells, particularly on brass sounds.

External This can select from footpedal, volume and breath for control of the filter

cutoff.

Key Although selectable as a mod source, it is not that worthwhile because this

is hardwired via the key follow parameter.

Lfo1 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.

Env1 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.

! Modwheel 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.
