Not sure about the bug, but if you have the svn of sc3-plugins, I have
a new pair of UGens for doing tapped delays. There is DelTapWr and DelTapRd. They are pretty cool and more efficient then the various PlayBuf based taps in the distro. You can get them here (and it may make what you are trying to do easier). http://sourceforge.net/projects/sc3-plugins/ They are part of the JoshUGens. Hope that helps.

It usually doesn't, and without seeing your code, it would be hard to know what the circumstances are.
