Mood music - Possible ?

[Killavirus]

when creating music for UT2004 i have heard it is possible for it to use mood music ??

so if you encounter an enemy or you enter a different part of the map it changes the track whilst keeping the bpm stable and in beat ??

If this is so how would i go about doing this ??? any help would be really welcome, even if its just knowing if its possible LOL.

and if so how ?

Thnx in advance :D

Incidental music?
2k4 doesn't monitor bpm. There's a music event trigger (at least that's what it was called in UT) that changes music. I've seen some mods use it or a version of thier own, sp mods mostly. Would be quite annoying in mp. This trigger just switches between 2 different songs. I believe the transition can be defined from immediate to gradual fades but it has nothing to do w/ tempo.

ok thnx so it would be bad to have any mixed beat loops
