|To work around this issue :|
Go in your Media folder(s), and delete all the Quickmount files and all the PK2 files (waveforms files).
Restart Pyramix and relink the medias, in Project drop down menu >Reconform > Relink to new media, with the following options :
Using current Media File Name (or Media Name) / Matching File Name (or Media Name) / Match exactly / Case Insensitive and Ignore TimeCodes options both ticked.
To re-generate the waveform, select all files, right click on it and select Display > Generate Image/Waveform.
You only have to do this relink process when opening your DSDIFF project one time, once saved in V 10.1, the files will relink properly next time you open your project.
