Adding Harmonics
Sinewave - Cheby mixed into 16 harmonics- random mixed, Creating formants.
Sonic Core Modular IV synth and Flexor modules:




RM testing

This old filter-RM trick seems to work:


FM testing

Complex FM patch:


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':

Roland_Kuit_PhaseDistortion

VOSIM

Rich timbres by creating pulse trains. 2 Modular IV and 2 NMG2 voices:

Sonic Core Modular modules

More elaborated fun:

Sonic Core Modular and Adern Flexor modules

Wave Animation
Digital oscillators are know for their static sound. In order to get the sound less static you can use the Wave Animation module:

Wave animator Roland Kuit


You will hear the dry sound slowly turned to wet and back again:


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

Roland_Kuit_WaveTerrain   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:



Roland_Kuit_WaveTerrain2

A demo of these complex waveforms, random tweaked:


Wave Animation and Terrain Synthesis

Roland_Kuit_WaveAnnimation



A combination between VOSIM and terrain architecture:

Modular voice experiment:

Feedback experiment in terrain synthesis

A little rhythm thing:

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:


Roland_Kuit_FB



Other tricks

The Envelope Generator as oscillator:

Roland_Kuit_EnvOsc

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

Roland_Kuit_PseudoPatterns


More fun with logic

Shaping waves by logic word scrambling:

Roland_Kuit_Logic_Scrambling

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:

Roland_Kuit_HarmonicPhaseOsc
 
Applying a LFO will shift phase automatic:

Roland_Kuit_PhaseOsc

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:

Roland_Kuit_PhaseOsc2

Creating your own harmonic phaser

Roland_Kuit_Phaser 3

Use and misuse of modules

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

Roland_Kuit_Animated_CV    Roland_Kuit_Terrain_CV
Animated control values                     Terrain control values

T
he weird sync

This patch has the feel of strange kind of Phase lock loop Synthesis:

Roland_Kuit_PLL

Soft sync

Soft sync can be done by comparison:

Roland_Kuit_Soft_Sync

Creating your own Noise:

Rich textures can be made by this:
