Thank you.

And how about the .mp3/.wav files that must play one time while pressing a key?
And if the sound is still playing, and you re-press the same key, the sound must start over.

Example:
I want to play a sound of 30 seconds on the key F4. When I press F4, the sound starts playing. If the 30 seconds are over, nothing more to do, just no loop.
If I press F4 again while the sound is still playing, the sound must reload and play. I hope somebody can help with this.
