Thank-you, Noel - that solved it - the rt is there now. Just as a supplementary Q for future reference, 1. How do I identify which realtrack is in which download? Is it as simple as the first two digits of the RT displayed in BIAB ties to the first two digits of the download? 31 in this case.
2. Also although at least two RT were missing, the reported number of RT's has not changed (2711), so I'm now wondering if there are others I now need to download as I did a piece a few months ago which called for a chamber ensemle where I had a similar issue of blank tracks & ended up doing the chamber stuff in midi in a DAW
