KeyMusic

KeyMusic is a lightweight application that assigns a different sound to each key on your keyboard. This way, you can play random melodies while you type.

The application includes more than 20 different sounds, ranging from a piano and various string instruments to firearms and even clapping sounds.

Apart from these basic features, the application also lets you change the tone and volume of the sounds. That way, you can customize the sounds a little bit, even if this isn't the main focus of the application.

KeyMusic is a fun application to play around with – or least it is in the beginning, before you get tired of it.
