I viewed this in Firefox and the Java console reported errors

=== Minim Error ===
=== Likely buffer underrun in AudioOutput.

which might explain why there is some jerkiness. Also you need a stop() method to release the audio resources used by the Minim library - see the examples that came with the library they all have this method.

By the way in Processing you might try Tools | Auto Format to tidy up your code will make it easier for you to see how your code is organized.

Nice applet just a couple of problems to solve.

i saw the error and a few looks at the forum showed it was pretty common...
i thought i ended a stop function - could be wrong - or perhaps did after i uploaded

re: the sloppy code - yeah - was getting lazy lol
