Pianosound in matlab

Single or multiple pianokeys sound at the same time.

Normally if you use a simple sinuswave for listening to the tunes the low keys cant be heard and the loudness of the sound varies. This is a simple solution where you instead hear the piano sound with more equal loudness when you choose to sound many keystrokes simultaneously.
