1. As starter, explore the Synthesizer functionality and get familiar with. You may start by clicking any key on the Synthesizer and it will produce sound!



2. You can play using keyboard too by click Show key checkbox to display keyboard bind and play based on it. Much easier to play this way isn't.



3. You also can try other key that not displayed in Synthesizer by input Custom key and press Play button. Noted that its only applicable from letter range of A until G together with 1 to 9. While Duration indicates the duration of note played, the more note adjusted the less duration key played.



Enjoy and have fun!
