PS :

(1). Cn ﹕Code of Channel, n = 1A , 1B , 2A , 2B , 3A , 3B , 4A , 4B.

(2). Sn ﹕Code of Sound,sort by sequence,n = 0 ~ 9999.

(3). Mn ﹕Code of Melody Song, sort by sequence n = 0 ~ 9999.

(4). Data : Code of Sound Sample Rate, the value is during 0 ~ 31, reference B.Sound Processor to get

more description.

(5). Reference C. Melody Processor to get more description of Tempo Code.

(6). Volume is during 0 ~ 63,0 is mute,63 is MAX volume.
