Hello,
First, sorry for my very bad english...
I'm a french art student and I try to make programs to visualize music in graphics.
I have a probleme with my last program: it memorize in a variable the FFT during 150 frames and display that to make a kind of field. That works for a while, but when I turn around the scene, after some time, processing write:

this is the code:

sorry, the code is long, but I don't know where is the problem .
