I've been "ro" for a week or two, just joined this list and just
started digging in to PD itself. I'm an old Csound guy, but the
real-time possibilites presented by PD with JACK got me interested.
I do, however, have a problem as well:
When I graphically select and drag/move multiple objects (say a simple
sub-patch copied from another patch), PD slows to a crawl, reports DIO
errors, and then immediately crashes. A full crash is less likely in
OSS and ALSA modes, but PD dies quite easily in this way when running
in -jack mode.
Is this a Tcl/Tk thing, an audio issue, my problem? It happens whether
"compute audio" is toggled on or off.
I am on a p4 2.4 with 1gb ram running PlanetCCRMA on Redhat 9 with pd
version 0.36-0. The card is an M-audio Delta 1010.
Here are the options I'm using:
bash$ sudo jackd -R -d alsa -d hw:0 -r 44100 -p 1024 &
...I have also tried other jackd buffer settings (-p). Then:
bash$ sudo pd -rt -jack -guishadow -cordcolor
It does the same when run as an ordinary user and/or with lesser
Thanks in advance for any insights.
