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 resonating tone – this

tone is basically what the Mystic produces. 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.
