Problem with ptplayer

[MacSpain]

Hi guys!

I've been working on a game for a couple of months, and recently I started adding some music via MOD files. I tried to play it using ptplayer, downloaded from here: http://aminet.net/package/mus/play/ptplayer.lha. I compiled it into an object file, linked it into my game, and called all the necessary functions. The result was not what I expected, The music sounds 'kinda' similar to the MOD file I load, but it's all high-pitched, and full of distortions. Does anyone know how to solve the issue? For additional info, my game works on an ACE engine: https://github.com/AmigaPorts/ACE. I contacted the maker of the engine, and he told me the steps to take to ensure that the system doesn't interfere with ptplayer.

ptplayer interfaced very well with my system friendly game. It hooks on level 6 interrupt, but otherwise doesn't disturb the game in my case, and the sound is good. Can you test with other mod files? some mod files play well on VLC but don't on regular amiga players.

note that sfx MUST use ptplayer too in order not to interfere. No external audio command should be performed.

Tried some other MODs as you suggested, and it turns out that it sounds the same for any MOD, which means that there must be something wrong with the way I set it up. The way I do it is like this:

1. Read the MOD file, and store it in the memory
*in an infinite loop*
2. disable system through ACE (has to be this way otherwise it crashes)
3. mt_install_cia (happens only once)
4. mt_init on the file in memory
5. mt_music
6. mt_end
7. enable system again (again, has to be this way)

I get that it would probably wrong to do it this way, but why does it sound the same no matter what file I try to play?
