As I use both Mac and PC, on my WIN XP machine I export a real track wav.file and the midi file.
The tune has been treated before and the Real Track export as AIFF file.
When I open the midi file on my MAC, I imported the AIFF files without any problem in Logic 8 and Digital Performer 6.

Today I open the new midi file and import the WAV files, both generated by BIAB 2010 XP version on a true PC (no parallels)

Logic 8 accepts the WAV file, BUT Digital Performer does not accept the importation ....

I don't know if this a Digital Performer problem or ... something else . Maybe I need to configure something somewhere . Thanks
