Music commands
0xFF XX	select voice XX from default bank in memory
0xFE end of track (if the 'L' infinite loop has been activated then it goes back there)
0xFD XX	select user voice XX
0xFC XX	set Timer B to XX
0xFB 00	signifies the beginning of a [] type loop
0xFA XX	signifies the end of a [] type loop, XX specifies how many times to loop, 
	0 is infinite, 1 is no loop
0xF9 XX	holds the currently playing note for XX amount of time
0xF8 XX	sets stereo panning.  XX is 1,2, or 3 multiplied by 64.
	the mml command 'p3' compiles to F8 C0, for example
0xF7 XX	sets volume of channel.  it works by adding XX to the base volume
	which is based on Total Level values.  at the bottom is a chart showing
	which operator's Total Level values to alter based on the currently selected algorithm

0xF6 XX	pitchbend up by XX amount of half-steps.  begins with next note played
0xF2 XX	pitchbend down by XX amount of half-steps 
0xF4 00	beginning of infinite loop (the 'L' command in mml)

0xF1 00 exit [] loop when on last time through (the ':' command. Z80 version only. Also only compiles with mmc2.exe)

0x01-61 XX play note 0x01-61 for XX amount of time
0x80 XX	rest for XX amount of time
