Merci André,
writePSfile works! (writePDFfile dont), but
after compiling one can use ps2pdf to get a PDF file.
(making sound synthesis & music composition with Python, I can now write the
music,
edit a visual score (on several pages) and insert pitches and chords above to
aid the perception).
Thanks for PyX !
