In the Master section, the following parameters are avail-
able:
Mystic
The synthesis method used by Mystic is based on three
parallel comb filters with feedback. A comb filter is a filter
with a number of “notches” in its frequency response, with
the notch frequencies harmonically related to the frequency
of the fundamental (lowest) notch.
A typical example of comb filtering occurs if you are using
a flanger effect or a delay effect with very short delay time.
As you probably know, raising the feedback (the amount
of signal sent back into the delay or flanger) causes a res
-
onating tone – this tone is basically what the Mystic pro-
duces. This astonishingly simple synthesis method is
capable of generating a wide range of sounds, from gentle
plucked-string tones to weird, non-harmonic timbres.
The basic principle is the following:
• You start with an “impulse sound”, typically with a very
short decay.
The spectrum of the impulse sound largely affects the tonal quality of the
final sound. To set up an impulse sound on the Mystic you use a slightly
simplified version of the synthesis found on the Spector synth.
• The impulse sound is fed into the three comb filters, in
parallel. Each of these has a feedback loop.
This means the output of each comb filter is fed back into the filter. This
results in a resonating feedback tone.
• 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).
Parameter Description
Glide Mode The available modes are: “held”, “on” and “off”. With
“held” selected, a glide effect only occurs for notes
played legato.
Rate Controls the glide rate – the time it takes for a note to
reach its destination pitch.
PB Range Controls the range of a pitch bend MIDI controller. Range
can be set between 1 and 24 semitones for a total of two
octaves.
Env Trigger When set to “Multi”, each keystroke re-triggers the enve-
lopes. When set to “single”, legato notes do not retrigger
the envelopes, effectively holding the envelopes on the
sustain level until all keys are released before a new note
is triggered.
Note Priority Defines which note is played when multiple keys are held.
Options are: First, Lowest, Highest, and Last.
Oct Controls the master pitch of Monologue in octave steps.
Range is ±4 octaves.
Master Out Controls the master output level that is sent to the VST
mixer. Use it to adjust the balance between different pre
-
sets. Use the VST mixer channel volume to control or au-
tomate the Monologue master volume.
Keyboard Pressing the “keyboard” button reveals a six octave virtual
keyboard. Pressing the “keyboard” button again hides the
keyboard and displays the master section again.
