Hi Anders -
I don’t think TS2 supports this and won’t in the future. From what I understand there is a separate project at IRCAM (“Partiels”) which will take forward the analysis and export of this kind of information(?).
While we wait for that I and many others have been using SPEAR SPEAR Homepage
This does some of the basic partials analysis and export as SDIF or as simpler text files of partials. OpenMusic’s OMTristan library does have some SPEAR import modules too which can be used in some cases as an alternative to the SDIF import modules.
Hope that helps(?)
