The included VST Instruments
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.
Crackle
This allows you to send noise directly into the comb filters.
Small amounts of noise will produce a “crackling”, erratic
effect; higher amounts will 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) will effectively turn
off the comb filter sound, as no feedback tone is produced.
• Setting Feedback to a positive value will create a feedback
tone, with higher settings generating longer decays.
• Setting Feedback to a negative value will create 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 will affect 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.
