Yamaha YMF262

From Wikipedia, the free encyclopedia

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.
