two extra points:
1) for files that are supposed to be a *part* of the session, i.e. you
want to "pretend" that they were captured as part of the recording
process, the path that is used to specify the file is NOT absolute (i.e.
it does not begin with / (or on windows system [A-Z]:). this indicates
that the file should be locatable within ardour's usual searched
directories, such as the one i named. for files that have an existence
outside the session (for whatever reason: they could be part of sample
libraries, or you just want to leave them present in the original
location that <other-DAW> put them in, or something else), the path
specification must be absolute.
2) there is no reason to write small parts of existing AAF files to a
new file. just specify the entire AAF file as a source, and later a
region that corresponds to the required data.
