Sounds could now have three components: An attack, a body made from a subtractive synth sound (saw or pulse wave through a filter) and an "embellishment" of one of many looped samples. (The looped samples also contained a collection of totally synthetic waves derived from additive synthesis, as well as sequences of inharmonic wave cycles.
The MIDI synth portion (both XG and VL) of the YMF chips was actually just hardware assist to a mostly software synth that resided in the device driver (the XG wavetable samples, for instance, were in system RAM with the driver [and could be replaced or added to easily], not in ROM on the sound card). As such, the MIDI synth, especially with VL ...
A synthesizer (also synthesiser [1] or synth) is an electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis , additive synthesis and frequency modulation synthesis .
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.
Its popularity was due largely to its relative simplicity. [6] Subtractive synthesis was so prevalent in analog synthesizers that it is sometimes called "analog synthesis". [ 7 ] It was the method of sound production in instruments like the Trautonium (1930), Novachord (1939), Buchla 100 (1960s), EMS VCS 3 (1969), Minimoog (1970), ARP 2600 ...

The related OPN2 was used in Sega's Mega Drive (Genesis), Fujitsu's FM Towns Marty, and some of Sega's arcade boards (e.g. Sega System C-2 and Sega System 32) as one of its sound generator chips. FM synthesis was also used on a wide range of mobile phones in the 2000s to play ringtones and other sounds, using the Yamaha SMAF format.
Vector synthesis provides movement in a sound by providing dynamic cross-fading between (usually) four sound sources. The four sound sources are conceptually arranged as the extreme points of X and Y axes, and typically labelled A, B, C and D. A given mix of the four sound sources can be represented by a single point in this 'vector plane'.
