Have you had clicks before? In my experience running Linux, I have had much fewer dio errors (basically none) running pd -rt on a *non* realtime kernel. I use the basic Ubuntu kernel with realtime privileges enabled, no running pd as root. I also do not use jack but alsa directly, which seems more stable. -------- Dan Wilcox danomatika.com robotcowboy.com
