The music of my game is stored as a number of large samples. These are 
played using the voice allocation commands, and the priority is set to 
255.

However, if I play a lot of other samples (using play_sample) at the same 
time, the music is sometimes cut off. When I say a lot at the same time, 
I mean many simultaneous samples, maybe twenty or more. Of course, there 
are not this many voices available, but I want the new samples to be cut 
off, not the music.

The music, btw, is in three stages. When one stage is finished, the next 
stage is started using reallocate_voice. Here is the bit of code which 
does it:

if (musictype <= 0)
 reallocate_voice (music_voice, (SAMPLE *)musicfile[ZOO_SHRINK].dat);
else
 reallocate_voice (music_voice, (SAMPLE *)musicfile[DLD_SHRINK].dat);
voice_set_priority (music_voice, 255);
voice_set_playmode (music_voice, PLAYMODE_LOOP);
voice_start (music_voice);

I don't know, maybe I have to set the priority AFTER calling voice_start. 
Or maybe the priority doesn't work....?

Btw, this only seems to happen on the second (interlude) music. The only 
difference I can see is that, unlike the other parts of the music, this 
part does not loop, it just plays once. Also, the final stage of the 
game/music will only start when the interlude music has finished. If the 
interlude music is cut off, the game will not end properly :(
