Synchronise the Time for Two or More Audio Clips

Hey guys,

The game that we're working on has to do with sound and music mostly. Now what we're having trouble with is trying to synchronise the Music Track. Basically, we have three instruments, and these will be picked up by the character. Once picked up, the music of that instrument starts playing. However, these need to be FULLY synchronised, which at the moment can't seem to find a correct answer.

So basically I need an answer in JAVASCRIPT to this scenario, if possible:

1. Character picks up instrument

2. Music of that instrument starts playing

3. After 30 seconds, character picks up second instrument

4. Second instrument track needs to start playing at its 30 seconds interval as well, not at 0 so it will be fully synced with the previous instrument. Music of First instrument still playing.

5. After 1 minute, character picks up third instrument

6. Third instrument tracks needs to start playing at its 1 minute interval as well, not at 0 so it will be fully synced with the previous instruments. Music of First & Second instruments still playing.

PLEASE NOTE THE FOLLOWING

1. Each instrument track is set as an AUDIOCLIP variable and cannot be different. Audio Source is definitely out of the question as it won't work of what we intend to do (already tried it)

2. The times aren't fixed, as one user might be faster/slower than another.

Thanks!
