Code to play salsa percussion rhythms in a web browser.
This is primarily of historical interest as the sound is produced through a Java Applet. Java is no longer supported by default in web browsers as it introduces security holes but back in 2008 when this was written they were still sometimes used.
The applet works by using the Java MIDI API (
The applet has no user interface of its own: its purpose is just to access the MIDI . To use it, compile the Java into a class and embed it in the web page using the "applet" tag (or the newer "object" tag):
<applet style="position:absolute; left:-1000" code="CreateAndPlay.class" height="1" width="1" name="rhythm">
The example above positions the applet off the screen so that it is not visible to the user.
document.rhythm.setMute(string: id, boolean: mute) // 'id' is the instrument name; 'mute' is a boolean document.rhythm.playSeq() // plays the drum sequence as a loop document.rhythm.playSeq(string: name) // plays the drum sequence as a loop using just the named instrument document.rhythm.stopSeq() // pauses the sequence document.rhythm.resetSeq() // stops and resets the sequence so that the next time it is played it starts from the beginning document.rhythm.setTempo(integer: bpm) // set the tempo of the sequence in beats per minute document.rhythm.getTempo(): integer // returns the current tempo in beats per minute
