	Yamaha - Wikipédia
		Yamaha achète Korg en 1989 et Steinberg en 2004.
		Yamaha sera, au début, un spécialiste du moteur 2 temps, comme deux autres japonais (Suzuki et Kawasaki), contrairement à Honda.
		Les années 1970 voient aussi l'arrivée de Yamaha dans le tout terrain (modèles trail) : DT 360 en 1973, DT 125, qui évoluera en DTMX (suspension cantilever), qui sera un énorme succès commercial.

		The YM2149 is a 3-voice PSG (programmable sound generator), used in the Atari ST, TT, and Falcon computers for the generation of sound.
		Designed and placed in Atari computers primarily with the intention of enabling the generation of tones, "bleeps", and synthesized music, the chip was soon used by resourceful programmers to play digital samples for music and sound effects in ST applications, games, and demos.
		Manufactured by Yamaha in the 1980's and 1990's, the YM2149 is an 8-bit chip capable of producing distinct 4096 tones.

		The Yamaha YM3526 OPL (FM-Operator Type L) was the bottom of the range in Yamaha's original FM synthesis chip line-up.
		The Yamaha YM2164 OPP was used in the Yamaha SFG-05 FM Sound Synthesizer Unit II and the Korg 707 keyboard synthesizer.

		This program emulates the Zilog Z80 microprocessor and the General Instruments AY-3-8910/8912 (or Yamaha YM2149) Programmable Sound Generator, in order to render an audio sample file in the Wav format.
		Currently there is no support of the ZX beeper, so some tune may be silent or not working at all.

		!A9 The Yamaha YM2149 is pin and register compatible with the AY38910, with the exception of pin 26 being unconnected TEST2 on the AY38910 and the SEL input on the YM2149.
		Max clock input is 2 MHz for the AY38910 and the YM2149 with SEL high (internally pulled up).
		If pin 26 is pulled low on the YM2149, the clock is halved so the max clock input is 4 MHz.

		From: kiki@uhunix1.uhcc.Hawaii.Edu (J. Wine) Subject: Yamaha FM-SSG music chip Date: 20 May 91 10:09:37 GMT [usurped from Yamaha manual #LSI 222030] To digitally produce the sounds created by a piano, violin, or flute, the number of operations which must be performed requires uninterrupted micro- processor operation.
		Although these devices can only generate square waves, they are in widespread use due to simplicity of control; systems which use them can be enhanced by replacing them with the OPN chips.
		The OPN LSI is manufactured using Yamaha's Si-gate NMOS process, It includes two sound sources: the FM system and the SSG sound sources.

		The medium gave composers great flexibility in creating their own "instrument" sounds, but because early computer sound chips had only simple tone generators and noise generators, it also imposed limitations on the complexity of the sound; chiptunes sometimes seem "harsh" or "squeaky" to the unaccustomed listener.
		Historically, the "chips" used were sound chips like the analog-digital hybrid Atari POKEY on the Atari 400/800, the MOS Technology SID on the Commodore 64, the Yamaha YM2149 on the Atari ST and ZX Spectrum, and the Yamaha YM3812 on IBM PC compatibles.
		Also, even with purely sample-based formats, such as the MOD format, chip sounds created by looping very small samples still could take up much less space.

	General Instrument AY-3-8910 - Wikipedia, the free encyclopedia
		The 8910 and its variants became popular chips in many arcade games, and was used on, among others, the Intellivision and Vectrex video game consoles and the MSX, Atari ST, Amstrad CPC, Oric 1 and Sinclair ZX Spectrum 128/+2/+3 home computers as well as the Mockingboard sound card for the Apple II family.
		It was also produced under license by Yamaha as the YM2149.
		Yamaha used the YM-2149 core to produce a whole family of music chips which were used in mobile phones, video games etc. For example, the YM-2203 (also known as OPN) is a YM-2149 plus FM.

		Your Atari ST computer contains a sound-generator chip that directly drives the speaker in its monitor, or any other acoustic device to which it is properly connected, and it's capable of making a wide range of musical notes and sound effects.
		Atari chose the Yamaha YM2149 software-controlled sound generator for their ST computers.
		Designed originally by General Instruments, this chip has been around for a number of years and, with all the current developments in sound generation, it seems obsolete by comparison.

		It also included a new 2-channel digital sound-chip that, like the Amiga, could play 8-bit stereo samples in hardware at up to 50 kHz (the Yamaha YM2149 could only be coaxed into playing samples by means of software trickery, and then only low-quality 4-bit mono at low sample rates).
		Despite all of this, it still ran at 8 MHz, and the enhanced hardware was clearly designed to catch up with, rather than improve upon the standard of the Amiga.
		An innovative music composition program that combined the sample playing abilities of a tracker with conventional music notation (which was usually only found in MIDI software) was called Quartet (after its 4-note polyphonic tracker, which displayed one monophonic stave at a time on colour screens).

		Chip music is music written using only the most elementary synthesis features of a computer or sound chip.
		Historically, this would mean the features of an audio co-processor like the analog-digital hybrid SID on the C64 or the Yamaha YM2149 on the Atari ST and ZX Spectrum.
		As newer computers stopped using dedicated synthesis chips and began to primarily use sample-based synthesis, more realistic timbres could be recreated, but often at the expense of file size (as with MODs) and without the personality imbued by the limitations of the older sound chips.
