Hello all,
I'm new to PD and this graphical programming thing but managed to get things installed on my Red Hat 7.0.1J (Kernel 2.2.16-22) Linux machine. First something to that point: I too, as the documentation mentions, had problems with "libtcl.so" and "libtk.so" The proffered solution (ln -s libtk8.3.so libtk.so etc.) did not work however because pd (pd-033PATCH1) was looking specifically for libt*8.0. Installing the rpm instead of compiling the .tar.gz distribution solved the problem though.
Anyway, that wasn't my main point. I'm having (only!) two problems at the moment. The first is with latency. I see in the docs talk about 8ms, 5ms, 3ms latency and how you can improve these lamentable figures (?!). At the moment I'm looking at about 1000ms latency when playing sound files :-( I'm using the OSS drivers and don't really have much choice about that because I made the mistake of buying a turtle beach multisound pinnacle card a few years ago. This card has never been well supported and it was only with extremely high curse factor that I got the bugger playing at all under Linux, but I can assure you now that there doesn't appear to be any latency when, for example, I press the play button on 'snd' from CCRMA. When I trigger a sound in PD with the mouse or keyboard however, I get about a 1 second time lag before the sound starts. And this no matter what combination of -audiobuf -fragsize -blocksize I care to use. Any ideas anyone?
The second problem is with sfplay~ and its open message. When I 'open' a longish file (that every other sound player seems to like well enough) without setting the optional header size etc. and then try to play it with 'sfplay~ 2 1000', I get no output. When, however I give arguments like "open 0 40 2 2 l" it plays ok, but of course skipping some samples and creating a click. Do I really have to work out how big my header is etc. to get this object to work? Any hints out there?
Apologies in advance for the verbosity and perhaps arcane English of this mail. All the best,
Michael
