MIDI/Ambient sound trouble.

Ok guys, im having a problem with playing ambient sounds.

Ambient sounds are midi's using a by blizzard made .dls file. I imported my midi and a modified version of GM.dls (the main midi instrument library) to save filesize of the .dls.

It all works, and I can play my midi... SOMETIMES! Without changing anything to the map it sometimes plays the midi, and sometimes doesnt.

at map init I stop the music and clear the music list. And 5 seconds in the game I use the commands:

Custom script: call SetAmbientDaySound("AshenvaleDay")
Custom script: call SetSoundVolume(bj_dayAmbientSound, 127)

The time of the day it between the checked values that SetAmbientDaySound uses so that cant be the problem.

Any ideas what could be causing a sometimes playing of ambient sound, and sometimes not?

P.S. I just noticed, the ambient sound plays if I hear wind rushing in the first 5 seconds. I guess that is the usual outland ambient sound for daytime, but sometimes that doesnt play either, and at that time my midi doesnt play either.

Hmm, correct me if I'm wrong, but why not use a mp3 instead of a midi? Im aware that mp3's use more filesize, however, I dont recall being able to use Midi's on B.net. Unless of course, you plan to use this for LAN and not B.net.

as you said. Filesize, right now im using <1mb for 8 minutes of music.

And yes it does work on battlenet. Just that it sometimes doesnt play an ambient sound.
