- *	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.
