I'm pretty new to pure data and I'm trying to write a patch that will loop a recorded sound but it has a little bump or click everytime it restarts. I've been trying to set it up so that I run two loops simultaneously, crossfading between them so that the clicks happen when the one clicking is at zero volume, if that makes sense. But I can't figure out the cross-fading part. I've read that polygate~ does crossfading, but I can't figure out how to use it. Can anyone help me? I've only been at this pure data thing for about a week, so I hope you have some patience.
