The chips are FM synthesizers and are capable of producing a wide range of sounds.
p Access to the device is through the MIDI driver.
p The .Nm driver usually attaches to a sound card, but it can also sit directly on the ISA bus.
p If .Dq flags 1 is specified, the .Nm driver handles left and right channels of OPL3 swapped. Use this flag if your device has such problem. .Sh SEE ALSO .Xr cmpci 4 , .Xr eso 4 , .Xr ess 4 , .Xr fms 4 , .Xr isa 4 , .Xr midi 4 , .Xr sb 4 , .Xr sv 4 , .Xr wss 4 , .Xr yds 4 , .Xr ym 4 .Sh HISTORY The .Nm device driver appeared in .Nx 1.4 . .Sh BUGS The OPL3 chip is operated in OPL2 mode despite being more capable.
