The Sputter

Every fart has a beginning, a middle, and an end. The end is where things fall apart.

In our model, the gas lives in a tank, which drains as the fart goes on.

Near the end, the flow starts switching on and off, in bursts a few hundredths of a second long. We call this the sputter.

The sputter dial decides how early the breakup starts. Turned nearly all the way up, it takes over most of the fart. This is Machine Gun.

Now, the same long fart, twice. First, with no sputter.

Then with the sputter dial at 60 percent.

With no sputter, the tone holds for 93 percent of the fart. With sputter, 68.

And as the pressure nears the line, the pitch gets shakier, and the whole thing tapers away.

Pressure, timing, tremble and release, all at once. That's why, in our model, the end is the hardest part.
