Hey guys I'm currently working on a sketch that uses FFT's and to make the background flicker different colours and to make a circular frequency "bar" thingy bounce in time with the music. What I'm having trouble with though is using millis().


I have a number of "if" functions so that at a 1:48 minutes into the program the frequency circle appears and then at 1:59 and 2:22 the alpha of the frequency circle increases. These changes are timed to beats and other things happening in the music but they keep happening too early (and not just by a few milliseconds either). Can anyone help?

Thanks.
