Phase Distortion

Phase distortion synthesis is a synthesis method introduced in 1984 by Casio in its CZ range of synthesizers, and similar to phase modulation synthesis in the sense that both methods dynamically change the harmonic content of a carrier waveform by application of another waveform (modulator) in the time domain. Casio introduced the term 'phase distortion':

Wave terrain
The Modular IV synthesizer contains 6(!!!) Terrain oscillators to make complex waveforms
.
CZ oscillators for X and Y input:

Modular synthesis   WT 1  WT2

Wave Terrain Synthesis is realized by the combination of two independent structures for generating sound signals. A trajectory signal (or orbit) and a terrain function. The trajectory is used to create a ‘path’ of coordinates that are used to read from a function of n variables f (x1,x2,…xn) , the terrain function. Most implementations use terrain functions of two variables f (x,y) but such systems can be creatively expanded into more dimensions.

Complex forms can be patched:

Feedback experiment between separate devices

Modular IV out - SC Plate X - SC Plate X- and back to Modular IV.
Again, the xMod/Fb module is needed

Other tricks

The Envelope Generator as oscillator:

Modular synthesis

The 'tuning', in this case, can be done by the A, H and D sliders.

Creating patterns
Cascaded Sample & Hold modules with a double feedback loop.
The Pseudo-Random Sequencer, or LFSR

More fun with logic

Shaping waves by logic word scrambling:

Modular synthesis

Here, the J9K DAC and ADC modules are used.

Phase

The phase of of a waveform is a mighty weapon in designing sound.

How to build a Harmonic Phase Oscillator:

Modular synthesis
 
Applying a LFO will shift phase automatic:

Modular synthesis

To make things more interesting, we apply a second LFO. This one is freq. modulated by LFO 1.
The amplitude of LFO 2, and thus its effect is modulated by LFO 1:

Use and misuse of modules

In modular synthesis there is no misuse if it works for you!
