On the above four terminologies for the classes of sound synthesis methods — i.e., (1) Wavetable synthesis, (2) Wavetable-modification algorithm, (3) Multiple wavetable synthesis, and (4) Sample-based synthesis — if these had been appropriately used to distinguish each other, any confusions could be avoided, but it seems failed historically.
Frequency modulation synthesis (or FM synthesis) is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. The (instantaneous) frequency of an oscillator is altered in accordance with the amplitude of a modulating signal. [1] FM synthesis can create both harmonic and inharmonic sounds.
FM synthesis is characterized as "harsh", "glassy" and "chilly". [3] Phase distortion synthesis, implemented in Casio CZ synthesizers, is similar to FM synthesis. [61] In wavetable synthesis, synthesizers modulate smoothly between digital representations of different waveforms, changing the shape and timbre. [62]
The Yamaha YMF278B, also known as the OPL4 (OPL is an acronym for FM Operator Type-L), is a sound chip that incorporates both FM synthesis and sample-based synthesis (often incorrectly called "wavetable synthesis") by Yamaha.

A number of sound synthesis methods for electronically producing sound were devised during the late 20th century. These include programmable sound generators (PSG), wavetable synthesis, and frequency modulation synthesis (FM synthesis).
The OPL series are low-cost sound chips providing FM synthesis for use in computing, music and video game applications. The OPL series of chips enabled the creation of affordable sound cards in IBM PC compatibles like the AdLib and Sound Blaster , becoming a de-facto standard until they were supplanted by " wavetable synthesis " cards in the ...
Sample-based synthesis is a form of audio synthesis that can be contrasted to either subtractive synthesis or additive synthesis.The principal difference with sample-based synthesis is that the seed waveforms are sampled sounds or instruments instead of fundamental waveforms such as sine and saw waves used in other types of synthesis.
