Piano Prime por mark

Piano Prime is a fun, and very simple to use Piano app for your Firefox browser.

This addon is a lite and very easy to use app for playing or learning Piano. You can play your favorite song with the built-in keyboard, or mouse. There is also an option to record desired song(s) and replay it at any time. In total, there are 52 keyboard keys but only 20 of them are visible when you install the App for the first time. This number can be changed from the options page. A setting is available to hide the built-in keyboard (top section). Moreover, sustain-control option makes piano bits to last a bit longer (for a more professional playing). Overall, this App is a user-friendly and very lite plugin available for your Firefox browser.

Some important features:
1. The App and all the settings are auto saved to the memory.
2. You can play piano with the keyboard, mouse, or the built-in keyboard at the top.
3. Number of visible keys are adjustable to your desired choice (default is 27).
