The included VST instruments
Raster
This removes harmonics from the impulse sound. As the
harmonic content of the impulse sound is reflected in the
comb filter sound, this changes the final timbre.
Comb filter sound parameters
Damping
This is a 6 dB/oct low pass filter that affects the sound be-
ing fed back into the comb filters. This means the sound be-
comes gradually softer when decaying, i.e. high harmonics
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 effect.
If you open the filter completely (turn Damping up to max) the harmonic
content is static – i.e. the sound does 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.
Crackle
This allows you to send noise directly into the comb filters.
Small amounts of noise produce a “crackling”, erratic ef-
fect; higher amounts give a more pronounced noise sound.
Feedback
This determines the amount of signal sent back into the
comb filters (the feedback level).
• Setting Feedback to zero (twelve o’clock) effectively turns off
the comb filter sound, as no feedback tone is produced.
• Setting Feedback to a positive value creates a feedback tone,
with higher settings generating longer decays.
• Setting Feedback to a negative value creates a feedback tone
with a more hollow sound, pitched one octave lower. Lower
settings generate longer decays.
Detune
This offsets the notch frequencies of the three parallel
comb filters, effectively changing the pitches of their feed-
back tones. At low settings, this creates a chorus-like de-
tune effect. Higher settings detunes the three tones in
wider intervals.
Pitch and Fine
Overall pitch adjustment of the final sound. This changes
the pitch of both the impulse sound and the final comb fil-
ter sound.
Key Tracking
This button determines whether the impulse sound should
track the keyboard or not. This affects the sound of the
comb filters in a way similar to a key track switch on a reg-
ular subtractive synth filter.
Portamento
This parameter makes the pitch glide between the notes
you play. The parameter setting determines the time it
takes for the pitch to glide from one note to the next. Turn
the knob clockwise for longer glide time.
The “Mode” switch allows you to apply glide only when
you play a legato note (when switch is set to Legato). Le-
gato is when you play a note without releasing the previ-
ously played note. Note that Legato mode only works with
monophonic parts.
