Each sound event is followed by a random delay which was generated by a Myhill distribution. Use the slider to slowly increase the Ratio value, and notice that the rhythm gets more and more drunkenly irregular.

The Myhill distribution can be thought of as a more flexible exponential
distribution; one whose variance can be controlled. This control is reflected
in a ratio whose value causes the Myhill distribution to more or less approximate

the exponential distribution. When the ratio is high (above 128), the
two distributions are indistinguishable. When ratio is low, the Myhill
transform generates increasingly regular, periodic patterns, as opposed
to the clustering and leaps of the exponential transform.

The Myhill distribution is found in com.softsynth.jmsl.util.EventDistributions

Essential code:

`class DensityJob extends MusicJob {`
` private double eventDensity;`
` private double ratio;`
` `
` public double repeat(double
playTime) {`
`
double dur = EventDistributions.genEntryDelayMyhill(eventDensity, ratio);`
`
double pitch = 60 + JMSLRandom.choose(12);`
`
double vel = JMSLRandom.choose(10, 20);`
`
double[] dar = { dur, pitch, vel, dur * 1.25 };`
`
return getInstrument().play(playTime, 1.0, dar);`
` }`

` public void setRatio(double

`
ratio = r;`
` }`
