Hello, sorry for my poor English (you know, French people...)
I used different software to get .wav files from flac, mp3 or others.
Often, 12keys doesn't consider them as .wav files.
I looked at these files, they all had extra tags (other than RIFF, WAVEfmt and data) or a "wrong" WAVEfmt size.
I didn't find any software (other than Switch) able to remove these extra tags.
Too bad 12keys doesn't do it itself or is not compatible...
Any freeware idea ? Otherwise I think I'll write my own piece of VBA ^^
