M. Wavetable

The Wavetable Synthesis was the first digital sound synthesis method developed at the end of the 1970s. The shape of a single cycle waves is described in a look up table as list of sample values. A look up table oscillator interpolates this table to produce waves of the desired frequencies by looping this table as long as the sound will last.

To enrich the dynamic of a sound you can mix two wavetables by digital interpolation.


It is also possible to morph (=continuous changing mixture) thru a series of wavetables. This wavetables can be regular snapshots in the time scale or snapshots of prominent points like the start (t=0), attack (t= max of the tone), decay (t= samplelength/4), sustain (t=samplelength/2) and end (t= 0.95 * samplelength).

The wavetables can be taken out of natural waves (record and automatically select appropriate waves) or from a collection of wavetables. For convenience they are collected in categories like vintage, fourier, natural, oligo or special. You can specify a series of wavetables by selecting the target wavetable (first click) and adding the source wave (second click) from the collection list.

You can also import a wave (*.wav or *.mp3) and automatically transform it to a series of wavetables by one click.

And you can create a series of wavetables by “Transform” any of the actual synthesizer sounds by one click.

This dynamic wavetable sounds can (like usual) be modified by the ADSR-modulator and all sound-effects.
