Thanks hans and Luigi for the hints on audiofiles. Sorry for late reply but I was out of home. In any case, I wasn't able to test because running context (as usual, from inside texshop) I obtain always this: TeXExec 5.4.3 - ConTeXt / PRAGMA ADE 1997-2005 fixing engine variable : pdfetex executable : pdfetex format : cont-en inputfile : test output : pdftex interface : en current mode : none TeX run : 1 This is pdfeTeX, Version 3.141592-1.30.4-2.2 (Web2C 7.5.5) (/usr/local/teTeX/share/texmf.local/web2c/natural.tcx) entering extended mode (./test.tex ConTeXt ver: 2005.10.27 fmt: 2005.11.9 int: english mes: english language : language en is active system : cont-new loaded (/usr/local/teTeX/share/texmf.local/tex/context/base/cont-new.tex FatalError : Your format does not match the base files!
