Noel,

Thank you. Problem solved! As I represent the worst combination of relative newbie and 'Old Codger' (63 years), it is so helpful to be able - when I come to a grinding halt - to call upon people who know the answers and are prepared to take the time and trouble to detail them.

One small point, which would be the cherry on the cake: having made a hybrid style - and this works perfectly - is it possible to change the style of the track again without re-editing the hybrid style? I can change the patch used, by right-clicking the track and selecting 'Select Midi patch', but any attempt to use 'Select Custom Midi style' for this track makes no difference. Not a 'show-stopper' as I can change hybrid style to do this, but would be more convenient if it could be done differently.
