Sketch lagging

Hey guys, me again.
I've got a pretty cool sketch worked out where I have numerous different "frequency circles" appearing and they disappear and re-appear over time using alpha only to eventually turn into really random flecks of colour across the screen.
I'm having some real difficulties though because the sketch is lagging so damn much that eventually all my nicely timed if functions end up being really out of time by a few seconds meaning that things don't change on the beat/at the right point.
Any help you guys could give would be great!
p.s. this time I actually made sure I was using the right milliseconds.
Here's the code;
