Thank you for the wonderful Sampler plugin. I can see it as having many uses in Quartz Composer.
However, I can't figure out how to use it to get the sort of "time trailing" effect I've been wanting, at least not without introducing a Queue into the composition. Which naturally brings back the problem I started with. I notice in your demo video with the Australian Dance Theatre there are some shots that seem to employ a time-delay effect. Were these queued from a loop sampled by your plugin? ------------------------------------------------- Bruno Degazio Sheridan College, Oakville, ON dega...@sheridanc.on.ca website: http://www-acad.sheridanc.on.ca/~degazio On 2012-04-18, at 6:33 AM, Tom Butterworth wrote: > I have a Sampler plugin which you might be able to use as a substitute for > the Queue - it takes time into account so will sample and play back at the > same rate. > > http://kriss.cx/tom/2012/04/sampler-2/ > > On 17 April 2012 12:53, Bruno Degazio <lifemu...@sympatico.ca> wrote: > On further testing I've determined that the Iterator is working fine.
