OM-Chant tutorials: SDIF issue


I am new with OM, I try to use the patches of OM-chant-tutorials-patches and I have a message error when I try to evaluate the sound object or any object linked to a sdif. For example, the error message of the patch number 4 : “Error while evaluating the box SYNTHETISE : Undefined operator sdif-open-file in form (sdif-open-file (om namestring path-sdif) :ewritefile).” How can I fix that problem ?

Thank you very much in advance,


Hello Raphaël-Tristan ,
This looks like a version-compatibility issue.
Make sure you have the latest versions of OM and OM-Chant to be sure everything fits together.
Let me know,

Ok thank you very much
