A finished version of the keymixer concept that works properly.
Also has more soundclips and multiple keyboards
Drag and drop sounds onto one of the three virtual keyboards - use up and down arrows to swap between them.
The sound will be attached to the corresponding key and keyboard that is active at that time.
The sound will go invisible when another keyboard is made active a sound will only play when the sound is visible and the key is pressed
(this may sound complicated but should make sense in the game)
Further instructions are in game.
