Hey how do i get this to work in battles on yanflys melody script?

Your questions are very very vague. Also, it's the wrong section so moving to Script Support.

So please elaborate. Audio Engine XT is a complex system. What does not work?

I am sorry.

the audio engine work fine for map audio and title audio...
but i cant seem to get it to play my tracks in battle, i figure this is cause im using yanflys melody script

I checked it out and yeah, the two aren't compatible. Melody is a beast to work with so depending of what exactly you want to achieve (you don't necessarily need ALL the Audio XT features), there might be an easier way than a compatibility patch.

thanks for checking your a legend. What im looking for is a way to use mp3's as audio for the game, i have a band recording the tracks for my project and i would like to put there songs in the game

You can use mp3s without any script.

"OH MY" never noticed. Thanks for the info. can you use mp3's with yanflys then?

Yes.

but not the battle background music?

What do you mean "the background music"?

I believe he's asking about how to use MP3s as battle music for Yanfly's system.
or
"So I can't use MP3s as battle music with Yanfly's system?

I don't know, his question isn't very clear.

how to use MP3s as battle music for Yanfly's system. is what i mean, sorry

What have Yanfly's battle system to do with the ability to play mp3? It should work the same.

Even if i change the battle music. It plays the default yanfly battle music. so it must be in the script right?

You wouldn't happen to be using YEM Party Influenced Music would you?
