Ok. So this "crash thing" can be somewhat resolved. BTW. I don't know if it helps, but in 0_37 devel pvoc.pd works fine with threaded soundiler.
the way the threaded soundfiler synchronizes with the main thread in devel_0_37 is not really clean...
As for the screwed sound in fft.examples patches it seems that it's not fft (at least not mayer fft) fault actually. I suspect that line~ might be causing problems, but I have to investigate it further.
i did some changes to line~, too ... but doing a short test, it seems to work fine on my machine ...
get back to you later ... tim
