DESCRIPTION    [Toc]    [Back]

     The opl driver provides support for the Yamaha OPL2 (YM3812)
and OPL3
     (YMF262)  chips.  The chips are FM synthesizer and are capable of producing
 a wide range of (mostly awful) sounds.

     Access to the device is done through the MIDI driver.

     The opl driver usually attaches to a sound card, but it  can
also sit directly
 on the ISA bus.
