Hi all,

Thanks for your responses. Atte, I wasn't aware that there was a python version of the application, or that it would be relatively easy to set up - I did get that working, so thanks for the tipoff.

Robin - thanks also. With your suggestion I did get paulstretch to compile correctly. I had tried running ./compile_linux_fftw_jack.sh earlier, but hadn't twigged that deleting PAaudiooutput.cpp would fix the problem.

Thanks again! Now I'm off to do some extreme timestretching.

Compile it with JACK and without portaudio support:
./compile_linux_fftw_jack.sh

Note: the build-script compiles *.cpp - yet no function from
PAaudiooutput.cpp is used in the JACK version. Either fix the
build-script or simply   mv PAaudiooutput.cpp PAaudiooutput.outoftheway

AFAIK Paul Nasca does still develop and maintain it.
