Basically I think my problems came from using array (and not table) to store a sample. Pd gave DIO errors when switching to the window containing the patch. Is this normal, and is there a way to avoid it, for instance running the gui in a separate thread? After switching to table (with very little testing, though) everything seems to work just fine :-) So the rest of this mail is releated to a patch using the problematic array!!! > i don't use pd-extended, but i think it's almost the same. the only > option missing is: -nosleep (useful for dual-core). I'm on a single core, so I guess -nosleep doesn't matter, right? > so be sure in qjackctl - setup: > Realtime > Periods/Buffer: 2 > Sample Rate: 44100 (or more) > Frames/Period: 256 (i am running at 64 without glitches) Something like that, although periods/buffer is 3 here (seems to work better in general with my sound card). > then for pd: > pd -rt -jack -r 44100 -nosleep -audiobuf 256 -channels 16 -alsamidi > -mididev 1 etc... Confused! 1) "pd -?" says -audiobuf is in ms, so 256 wouldn't make sense, or...? 2) I thought that jack clients automatically got the same buffer size as jack, which means that is doesn't make sense (or any difference) to specify that for the client. Same with -rt, I thought that clients "enherited" the realtime priority from jack... > and finally, be sure to edit /etc/security/limits.conf: > @audio - rtprio 99 > @audio - memlock unlimited > @audio - nice -20 > > and of course, add yourself to audio group (reboot to be sure). let us > know.

I now tried with openbox (lighter than icewm) and the problem is the same. -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
