JFugue 6. Rhythm

The percussion sounds of midi instruments are on channel 10, or voice 9 in JFugue (V9).

In JFugue, we can use layers to deal with percussive sound. In example1(), we see how layers may be used. One bar of music is defined, 'O' is for BASS_DRUM and 'X' stands for HAND_CLAP, both of 8th note duration. The '.' indicates Rest of 8th note-duration. In example2() through example5(), we see alternative ways of creating same sound. We also have 5 buttons that will run one of the five example methods.
