Cubase Sx 3 and 4 both do OMF files fine. Make sure that all
files are checked in the OMF export page and that you are using OMF 2 and check export all to one file. OMF does not support 32bit floating point files so if he is using that bit depth he should convert to 16 or 24 bit. One other consideration is that digitranslator can not handle stereo audio files so any stereo audio file needs to be split to a dual mono file. OMF
handles stereo files fine just not digitranslator..
