^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) * For example setting the rightmost bit (0x01) changes the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) * first voice on the right side to the 4 OP mode. The fourth

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) * If a voice is set to the 2 OP mode, it works like 2 OP modes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) * of the original YM3812 (AdLib). In addition the voice can
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) * be connected the left, right or both stereo channels. It can
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) * even be left unconnected. This works with 4 OP voices also.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) * The stereo connection bits are located in the FEEDBACK_CONNECTION
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) * register of the voice (0xC0-0xC8). In 4 OP voices these bits are
