Hello Everybody!

Inspired by Andre michelle, I`m building a tone matrix in AS3.  
I managed to create the matrix and generate the different sounds. They don´t sound that good, but I´m getting there 🙂  
One big problem I have is when more than one dot is set to play, it sounds just horrible. I googled a lot and found the additive synthesis method but don´t have a clue how to apply it to as3.  
anybody out there knows how to play multiple sounds together? any hint?

my demo is [URL=“[http://www.inklink.co.at/tonematrix/](http://www.inklink.co.at/tonematrix/)”]here

any help is more than appreciated!  
thanks!
