- *
- *
- * The OPL-3 mode is switched on by writing 0x01, to the offset 5
- * of the right side.
- *
- * Another special register at the right side is at offset 4. It contains
- * a bit mask defining which voices are used as 4 OP voices.
- *
- * The percussive mode is implemented in the left side only.
- *
- * With the above exceptions the both sides can be operated independently.
- *
- * A 4 OP voice can be created by setting the corresponding
- * bit at offset 4 of the right side.
- *
- * For example setting the rightmost bit (0x01) changes the
- * first voice on the right side to the 4 OP mode. The fourth
- * voice is made inaccessible.
- *
- * If a voice is set to the 2 OP mode, it works like 2 OP modes
- * of the original YM3812 (AdLib). In addition the voice can
- * be connected the left, right or both stereo channels. It can
- * even be left unconnected. This works with 4 OP voices also.
- *
- * The stereo connection bits are located in the FEEDBACK_CONNECTION
- * register of the voice (0xC0-0xC8). In 4 OP voices these bits are
- * in the second half of the voice.
