The Included VST Instruments
Mystic
• When the signal is fed back into the comb filter, it goes via a separate, variable
low-pass filter.
This filter corresponds to the damping of high frequencies in a physical instrument
– when set to a low cutoff frequency it causes high harmonics to decay faster than
the lower harmonics (as when plucking a string on a guitar, for example).
• The level of the feedback signal is governed by a feedback control.
This determines the decay of the feedback tone. Setting this to a negative value
simulates the traveling wave in a tube with one open end and one closed end. The
result is a more hollow, square wave-like sound, pitched one octave lower.
• A detune control offsets the fundamental frequencies of the three comb filters, for
chorus-like sounds or drastic special effects.
Finally you have access to the common synth parameters – two LFOs, four envelopes
and an effect section.
• By default, envelope 2 controls the level of the impulse sound – this is where you
set up the short impulse decay when emulating string sounds, etc.
Ö The signal flow of the Mystic synth is illustrated in the section “Diagrams” on page
212.
Sound Parameters
The Impulse Control Section
This is where you set up the impulse sound – the sound fed into the comb filters,
serving as a starting point for the sound. The Impulse Control has two basic
waveforms that are filtered through separate spectrum filters with adjustable base
frequency; the output is an adjustable mix between the two waveform/spectrum filter
signals.
Spectrum Displays
The displays allow you to draw a filter contour with your mouse for spectrum filters
A
and B.
• To set up the contour, click in one of the displays and drag the mouse to draw a
curve. Note that this produces 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.
