I'm relatively new to Pure Data and I've been trying to use it for a performance piece, basically the patch offers the option of selecting a loop to play and there is a variable speed control. My issue is that I need the audio to stay synchronised with the video as the speed is varied.

I've tried to attach the patch with the relevant files, but for some reason the zip file won't upload, so it is available at: http://www.sendspace.com/file/zj7u6l

If anyone can help I'd be immensely grateful!

I'm trying to work on a project in which any movement leaves a trail/motion blur behind it (similar to this light painting effect

I was originally looking at pix_biquad, but I've been told that likely won't be up to the task.

Any ideas?!
