PLEASE PLEASE PLEASE! Phillipe, this is fast becoming an truly essential requirement.
Many guys I know (including myself) using Cubendo that work with large 5.1 (Polywav) RF64 files, would find the error checking facility (and all the other great functions that ONLY Wavelab has) as totally invaluable.
Please consider at least support in handling RF64 multichannel wavs the same way as stereo, even if for time being, we only have stereo output for monitoring!
