I've coded an app which has 8 buttons on the screen. Each Button has an touchstart and tochend event. If I press more then one button at the same time, not any event is realy fired. I think it is because events can't be processed at the same time.

The Problem is that I play a sound when a button is touched and I stop it when the button is released. Some of the sounds play, even if the screen is not touched.

Is there a possibility to check the state of the button to check manually if the button is still touched?
