Hi, Thanks for you answers. I downloaded the packages from http://www.cs.bath.ac.uk/jpff/Csound5/debian/. Then I installed libcsound64-5.1_5.07.0.dfsg-2_i386.deb, csound_5.07.0.dfsg-2_i386.deb and csound-gui_5.07.0.dfsg-2_i386.deb. I could render an example to a wav file. I tried also python-csound_5.07.0.dfsg-1_i386.deb but got an error: Dependency is not satisfiable: python (I have 2.4 and 2.5 installed). Regards, Radu
