💖 DESCRIPTION 💖

The opl driver provides support for the Yamaha OPL2 (YM3812) and OPL3 (YMF262) chips. These chips are FM synthesizers, and they can produce a wide range of sounds — iconic little noise machines fr fr. 🎛️✨

Access to the device is through the MIDI driver. 🎹

Usually the opl driver attaches to a sound card, but it can also sit directly on the ISA bus. Highkey versatile. 💅

If flags 1 is specified, the opl driver handles the left and right channels of OPL3 swapped. Use this flag if your device has such problem. 🫶
