I found the problem. Remember it is possible to disable a MSX-MUSIC.
Disabled is ignore writes (still need to find out if only IO-ports or both
IO and memory are ignored). We didn't know that MSX-MUSIC was enabled or
disabled at power-on. Maybe it was enabled in software by FM-PAC ROM.
Well now we found out, MSX-MUSIC is enabled at power-on and the FM-PAC ROM
does not automatically enable it.
