YAMAHA YMF262

The 'Yamaha YMF262' also known as the 'OPL3' (OPL is an acronym for ''FM Operator Type-L''), is an improved version of the sound chip Yamaha YM3812 (OPL2). It adds the following features:

★ Twice as many channels (18 instead of 9)

★ Simple stereo (hard left, center or hard right)

★ 4 new waveforms (alternating-sine, "camel"-sine, square and logarithmic saw)

★ 4 oscillator mode (combines 2 channels together, for maximum 6 channels)

★ Less time spent busy-waiting for a response from the chip, improved latency and system performance (the OPL2 required pretty long delays)
This chip is used for the Sound Blaster Pro 2.0 and for the MSX sound card MoonSound (in conjunction with the Yamaha YMF278).
