hello,
first i want to thank you for the suggestions!
i got the problem near to solved by increasing the
buffersize as guenter suggested.
pd 0.34.2, s_linux.c, near line 666:
...
if (linux_fragsize)
/* post("warning: overiding blocksize to 64!");
linux_fragsize = 64; */
post("hack: warning: overiding blocksize to 1024!");
linux_fragsize = 1024;
}
...
i still get loops sometimes - they sound lovlier now :-) but i can
rearrange the pd patch o avoid them.
on the long run i consider to apply the low-latency kernel patches.
(demudi will come with them, i guess?)
thank you all again
