Firstly, is it possible to synch sounds? i.e. have a base track (melody) playing, then on mouseUp (or something) bring in a beat or another sound element, synched to the underlying base track?
If someone has done summin similar, can you post a link or PM me, I am very interested to discover if this is possible and how to achieve it.
This is just an idea:
How about running the two sounds from the beginning and have the volume set on the base track at 100 and the beat on 0; kind of like using _visible for a movieClip. Then on your event, change the volume level of the beat up to 100. Basically they would both be running all the time (and in sync) and you would just turn the vol up and down. Just a guess.
