Sorry if I misunderstood, but if all you want to do it play music from Timer-C at 50Hz without messing up hdd/fdd it is really simple:
init:
move.l $114.w,save_c
move.l #my_c,$114.w
my_c:
subq.w #1,.hz50
bne.s .not50
move.w #4,.hz50
movem.l d0-a6,-(sp)
jsr playmusic
movem.l (sp)+,d0-a6
.not50:
move.l save_c,-(sp)
rts
.hz50: dc.w 4
exit:
move.l save_c,$114.w
That code will keep the OS at 200Hz and your music at 50.. Again sorry if I misunderstood the intention.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
