ABOUT ANALOGUE SYNTHESIS
Sync Skew also effects the standard Square & Saw waveforms. The effect is to “swash” the waveform at the end of its cycle with
positive modulation & swashing the waveform at the beginning of the cycle. On a square wave, moderate amounts of this effect
produce similar effects to Pulse width modulation except width modulation over 100% can be achieved allowing may cycles to be
“swashed” into one original one. This can also be described as Frequency Modulation within the cycle & so mimics classic “Cross
Modulation” with a Saw wave. This can produce effects similar to Sync but when this parameter is used in conjunction with
Formant Width the results can be very different. Below are examples of Sync Skew on standard Square & Saw waveforms. Note
how the wave is swashed at one end & more than one cycle has been swashed into the original cycle.
Formant width is a parameter that controls the level of the cycles of the “virtual” slave oscillator. This can be used to simulate reso-
nance within the oscillator itself by using the “Harden” parameter to smooth out the sharp edges of this wave form. The effect is to
reduce the level of every successive slave cycle. Additionally this parameter has an effect on the normal Saw & Square waveforms.
The effect is to boost the treble content of these waves.
Both Sync Skew & Formant Width can be used in conjunction to create yet even more waveforms. Below are examples.
Analogue Sound Modelling technology allows even more control over the waveform. Once you have selected you basic oscillator
waveforms you can further modify then using a “Hardening” process. This “Hardening” rounds off all the “Sharp” edges of the
waveform, thereby reducing its harmonic content. Below is an example of the “Harden” parameter on a Square wave.
