Ah ... the plot thickens.

There's a solo track that claims at the start to be an electric guitar (which also shows on the notation view), but the moment BIAB starts the count-in, it changes to oboe and _that_ track is the source of the vibraphone sound even though it shows oboe through the first chorus.

On the second chorus, it still shows oboe, but it plays electric guitar, through to the penultimate chorus, after which it stops playing for the final chorus when the melody returns.

OK, right ... step-editting the soloist trach shows patch change events: First Electric guitar, then immediately Vibes (which does _not_ show on the notation view), so that's where the vibraphone sound comes from. There's a later patch change also to electric guitar. I've now deleted the Vibes and the second Electric Guitar.

Now when I play, despite the patch change to Electric guitar, the soloist track changes to oboe, but does now at least play an oboe. The soloist is silent on the first chorus, but now plays second chorus to the end (though I've now reduced the number of choruses from 6 to 3). No electric guitar. Next I changed the soloist track via the mixer to "no MIDI patch", played a few bars, stopped, selected via the mixer MIDI Electric Guitar and now it's playing electric guitar as I would expect.

I still have no idea where the oboe came from.


Another minor oddity I note is that, after stopping play with the Pause button, I have to click twice on the Play button to get BIAB to play.
