Beep is a very powerful browser-based keyboard JS plugin. The keyboard plugin can display the notes of the sound at the same time, and comes with a presentation function that can play the complete music of the specified song. The keyboard plug-in supports playing with keyboards and using the mouse to slide over the keys.
Beep is the keyboard JavaScript framework that creates synthetic music effects based on the Webaudio API. It is used to simulate the real piano playing environment. Use one line of code synth = new BEEP. Instrument () can create a set of trigger interfaces that trigger notes, each with its own tonal voices. Using the Synth.scoreplay () method, you can make the keyboard plugin automatically play the default tune.
