Application instructions:
To play the piano, simply click the keys with the mouse. Besides just playing, you can record the keys you play and have the piano play it back. Just click the 'Record' button before playing, and the piano will store up to 60 keys. The stored keys will be listed on the screen below the piano. To stop the recording, click the 'Stop' button. To play the recorded keys back, click the 'Play' button, and to stop the playback, click the 'Stop' button. If you wish to clear the recorded keys simply click the 'Clear' button. Furthermore the piano contains four small demo recordings, which can be accessed by clicking first one of the four demo buttons, and afterwards clicking the 'Play' button. You can change the language of the interface by clicking the flags.

Problems running the application:
First of all, to run the application you will need to have Java installed. If you don't have that already, then you can install it from here:

If you still cannot run the application and are getting a message about your security settings, then it's because the newest versions of Java are overdoing security to such an extent that Java applets now as default cannot run unless they are signed by an official certificate authority. That's a bit too much for a simple application like this, but at least there is a way to get it to run without being signed. Simply add my website to your list of trusted websites (if you do trust it). Then instead of the application being completely blocked from running, you will now get a security prompt where you can choose to run it or not. Here's a link to the official instructions on how to add a trusted website:
