Dirtywave M8 Operation Manual
VOSIM
This model uses a combination of 3 oscillators arranged in a clever ring-modulation/
hardsync patch to emulate formant synthesis - a technique named VOSIM and de-
scribed by Kaegi and Tempelaars. COLOR and TIMBRE control the relative frequencies
of the two formants.
VOWEL, VOWEL FOF
Both models synthesize vowel sounds. VOWL is a faithful recreation of early computer
speech synthesis programs. VFOF uses a simplied version of Rodet’s FOF synthesis
technique. Both have the same control layout: TIMBRE controls the vowel, morphing
between a, e, i, o, u. COLOR shifts the formants in frequency. Main oscillator frequency
and COLOR can be used altogether to simulate age and gender transformations.
HARMONICS
This model uses additive synthesis, by summing 12 sine harmonics. COLOR modies
the distribution of the amplitudes of each harmonics, around a central frequency set by
TIMBRE.
FM, FEEDBACK FM, CHAOTIC FEEDBACK FM
Three avors of 2-operator phase-modulation synthesis. TIMBRE controls the modu-
lation amount. COLOR controls the relative frequency interval between modulator and
carrier. FM is a well-behaved implementation. FEEDBACK FM uses feedback from the
carrier to itself to produce harsher tones. CHAOTIC FEEDBACK FM uses two feedback
paths, from carrier to modulator and carrier to itself to achieve droning, unstable tones.
PLUCKED
Raw plucked string synthesis. TIMBRE controls the damping, COLOR the plucking
position.
BOWED
Bowed string modeling. TIMBRE controls the friction level, COLOR the bowing posi-
tion. A trigger or gate signal is required. Note that this model does not include a body
lter - which would be necessary to simulate an actual string instrument.
BLOWN
Reed instrument model. TIMBRE controls the air pressure, COLOR the geometry of
the instrument. Note that this model does not include a lter - which would have been
necessary to simulate an actual instrument.
