  • working metrenome for preview/renders?

    Posted by Erin Shelby on June 15, 2007 at 12:29 am

    I was going to just go into garage band and make a long wave file, but it dawned on me that some of you expression geniouses may have a way to do this. What I want to do is have a metrinome playing as i watch previews (w/ audio, of course) or renders. I know I could use the ‘tone’ effect or maybe one wav file looped somehow, but wondering how I could time it so I get a nice ‘click’ on a nice 4/4 beat? Possible? Or should I just do it a different way.

    Enable time remapping on your click layer and try this expression:

    freq = 120; // beats per minute

    t = 60/freq;
    time%t

    Your click needs to occur at the start of the layer. Sounds pretty funky if you use something other than a simple click.
