How to cache samples ?

[MarlBurroW]

Hi !
I'm building a multiplayer game with your instrument (real time game with socket.IO). In my game, each player has it own instance of your piano to avoid note conflict.
So each time a user join a game, all clients loads all samples for this new player and it cause performance issues for other players (mainly delay on socket and UI).
How can I cache all samples to avoid unnecessarry redundant requests ?
Thanks
