What the program does it grab the music channel data, splits it into 4 parts (using a modified version of the spectrograph bar routine from the BASS module), calculates the volume difference and uses that to decide whether to start creating the arrows. It always grabs the data as often as possible.
At the moment the music is streamed - this is no real problem now, but I may change that.
Its always around 4/5 seconds behind or so (or rather it appears to be) because it scrolls up from the bottom of the screen (and there is no lead-in). Its something to change later on, along with many other things, including hi-score table, fix options text (it should be noted that most of the text is designed to be international), outro, loading system.
