Sync digital switch with Timer/timed sequence
Nov 24th, 2008, 2:01am  
Hi,

New to Processing...

I would like to use Processing to create a dance pad game... and would love some advice (free code?) on how to synch up a digital input against a timed piece of music.  

So when the digital switch is input at the right time in the music, I can program processing to draw stuff and provide visual feedback.

This is probably a simple couple of lines, but again I'm a newbie...

Any ideas?  THANKS!!!

if you know how many milliseconds == a beat in your music, you should be able to use millis() --

(if millis() - lastBeat >= beatTime){
   lastBeat = millis();
   dostuff();
}

but if you're talking about a beat detection library, I don't know whether that reports in milliseconds.
