sorry, if this is obvious, but are you running jack and pd in realtime mode? jackd -R / pd -rt (probably the latter isn't necessary when running over jack) if i am not totally mistaken, the pd graphics shouldn't have an effect on the audio part, since they are running in two differennt threads, pd and pd-gui. so, a higher priority of the pd thread over the pd-gui thread should already help (which is the case, if you run pd/jack with realtime priority). unfortunately, there are cases, where there are interferences between both threads; for instance when moving around an array with 1'000'000 elements. i get clicks when i open a subpatch containing a big array, but not when opening a subpatch containing only message boxes and objects. @experts: if there are gui related drop-outs such as when displaying an array, is that because this amount of data causes a jam on the socket? is the socket the bottleneck here? roman ___________________________________________________________ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
