Thanks to you for your replies !

Considering the fact to have mono files instead of poly files, it’s quite possible with the 788T. But the handling of these files for the syncing in FCP is more tedious than with “single” and simple poly files. And what upsets me is that a poly files with three or more channels is correctly interpreted but not a poly file with two channels…
It’s as if two channels automatically means stereo for FCP !
