...well, I guess you've already seen the other posts, and I just wanted to come down on the side of "realtime isn't very helpful on OSX"...which brings up a question or two that I had posted, oh, last week, but which were quietly unanswered:

• does pd.watchdog only get invoked if using the "-rt" flag? I don't

seem to notice it otherwise...and lately it doesn't print anything but a carriage return: is this correct?

...also, I would strongly recommend removing the schedule priority setting stuff, especially if using GEM, because it allows pd to take over the machine, thus necessitating a reboot! This may be sparked by the extremely inefficient implementation of TCL/TK on OSX, as it seems to happen when changing parameters "on the fly" via number boxes or the like...again to repeat a previous post:

"searching through the code, I found that the param.sched_priority "fix" has worked it's way into s_inter.c:833:848...if I remember correctly, this was a "fix" for audio glitches? The problem with using it and GEM is that it makes pd a higher priority than the window manager, and so it's very easy to get locked out, forcing a manual reboot! If audio people really need this (I thought the audio glitch was fixed elsewhere, too?), could we make a compile flag to disable this? Also would be a good idea to notify people who are using this current version and GEM to be ready for a lock out and sadness..."

good luck, jamie
