Wave Table Oscillator

This oscillator provides two tables of 16 waveforms each.

Morphing takes place in three dimensions by taking the waveform from each table after each index is modulated and combining them with the choice of several mathematical operators, which themselves can be modulated, to create a third composite waveform.

The audio engine works behind the scenes while you make edits to maintain an alias free oscillator.

Depending on the modulations used, the engine will compute the Fast Fourier Transform on either the final composite, or on all the individual table waveforms before they are combined.


Operand

The operand table on the left side consists of 16 waveform positions controlled by modulated index.

Composite Waveform

The composite waveform in the center is formed by morphing between the two tables, or by performing addition, subtraction, phase or pulse width modulation between the operand and operator waveforms in real-time.

Operator

The operator table on the right also contains 16 positions, and likewise can be modulated.

Load Any Waveform

Each position in both wave tables can be loaded with any waveform created by the Wave Draw editor.

Import Your Own Waveforms

You can also import any single cycle WAV file by simply dragging and dropping the file onto the graph for a selected position.

 

Table Fill

The Table Fill feature enables you to create perfectly smooth waveform transitions without editing all the positions. Simply edit the waveforms you want at the desired positions and hit the Fill button.

Fast Editing

The interface helps you work quickly by enabling you to alternating between the wave table interface and wave draw editing by simply clicking on one of the wave graphs in either table.

Skip Cycle Oscillator

Skip Cycle processing is used to create rich bass textures within a single oscillator while maintaining note tonality. 

The Skip Cycle dial allows you to apply morphing, addition or subtraction of the operand to alternating audio cycles in the composite waveform.  

In this diagram the operand consists of a simple saw tooth. The operator is a pulse with frequency set to four which is subtracted from the operand every third cycle.
