MetaSynth incorporates additive, wavetable, granular, and FM synthesis.
Additive synthesis uses sine waves to create complex sounds.
Wavetable synthesis produces a sound by sequencing it through a table of modulations, or different waveforms, through the duration of a single note. These sounds usually have a rhythmic quality. FM synthesis requires at least two signals, with one signal modulating the other. In addition to the arsenal of syntheses, MetaSynth contains a thousand-voice sampler. After rendering, the output is loaded into MetaSynth's Sample Editor.
