Ohh ... now that's odd!

I realiosed that the first solo appeared not clarinet as I'd expected, but a saxophone, so I clicked on the soloists track on the mixer, opened the RealTracks picker, then the Medley dialog. Only one instrument! Just the clarinet and in the first chorus when the track plays nothing. And yet, the middle choruses are playing solos as I'd expected ... from where?

I can solo the soloist track on the mixer and the soloists definitely play there.

There are no tags on the notation window for patch/RealTrack changes.

But they're probably soloists that I'd set up fromn the previous song (well, it's the same song, but configured again starting from the original SGU rather than the MGU that I'd saved).

I imagine that if I set up a new RealTracks medley, it will replace whatever is there at present, though for the moment I salln't do that as what I have at present may have useful clues if this is wayward behaviour, which at present is certainly how it seems.
