Shatterhand, actually, Turrican does mute music channels. At least Turrican 2, as far as I remember.
Try detonating a bomb and listen with attention.

I've never noticed this. But if it's just with the bomb, maybe it mutes the music just for an extra ooomph?

I am also pretty sure other games do that. Stardust come to mind now. NEarly sure Elfmania does it too.

yes sfx mute 1 music channel, but the other 3 channels remain working with music
if you pay attention on turrican 1 and 2 you will note it, specially if you keep pressing the fire button

I don't think so.
I cant play the game now but I Am sure it mutes stuff. Just cleverly.

For turrican 2 is special player:
4 virtual chanel mixed in 1 real channel
3 classic chanels
= 7 channels used for music and SFX

some mod replayers are lazy and waste cycles when writing to dma before issuing more sound commands (else the sound is choppy or corrupt). A lot of soundtracker routines to that infamous active cpu loop, which wastes power (not a problem in menus or loading screens, but can be an issue during the game, including sprite glitches or refresh issues)

Clever replayers like phx ptreplay use cia timer interrupt 6 to know when to apply the new sound command, and in the meantime, the game logic/graphics/whatever can run.

if the games uses standard modules, maybe it's possible to replace mod replayer by phx mod replay and plug the sfx on it... and get faster games

That would be a nice whdload project (also not trivial)

that or CD32load CD slaves for CD music + sfx ... only on the best amiga console
