The included VST Instruments
Spectrum displays
Allows you to draw a filter contour with your mouse for
spectrum filters A & B.
• To set up the contour, click in one of the displays and
drag the mouse to draw the desired curve. Note that this
will produce the inverse contour in the other display, for
maximum sonic versatility.
To set up the contour independently for the two filters, hold down [Shift]
and click and drag the mouse in either display.
• Use the Preset pop-up menu to select a preset contour
if you like.
• If you want to random calculate a spectrum filter curve,
you can choose the Randomize function from the Preset
pop-up.
Each time you choose this function, a new randomized spectrum will ap-
pear.
Waveform pop-up
The pop-up at the bottom of the waveform section (the
central box at the top of the panel) allows you to select a
basic waveform to be sent through filter contour A. The op-
tions are especially suited for use with the spectrum filter.
Cut
This offsets the frequency of the filter contour, working
somewhat like a cutoff control on a standard synth filter.
To use the filter contour in its full frequency range, set Cut
to its maximum value.
Morph
Adjusts the mix between the two signal paths: waveform A
spectrum contour A and waveform B spectrum contour B.
Coarse
This offsets the pitch for the impulse sound. In a typical
“string setup”, when the impulse sound is very short, this
will not change the pitch of the final sound, but the tonal
color.
Raster
This removes harmonics from the impulse sound. As the
harmonic content of the impulse sound is reflected in the
comb filter sound, this will change the final timbre.
Comb filter sound parameters
Damping
This is a 6dB/oct lowpass filter that affects the sound be-
ing fed back into the comb filters. This means the sound
will become gradually softer when decaying, i.e. high har-
monics to decay faster than the lower harmonics (as when
plucking a string on a guitar, for example).
• The lower the Damping, the more pronounced this ef-
fect.
If you open the filter completely (turn Damping up to max) the harmonic
content will be static – i.e. the sound will not get softer when decaying.
Level
This determines the level of the impulse sound being fed
into the comb filters. By default, this parameter is modu-
lated by envelope 2. That is, you use envelope 2 as a level
envelope for the impulse sound.
• For a string-type sound, you want an envelope with a
quick attack, a very short decay and no sustain (an “im-
pulse” in other words), but you can also use other enve-
lopes for other types of sounds.
Try raising the attack for example, or raising the sustain to allow the im-
pulse sound to be heard together with the comb filter sound.
