Thank you so much guys for your invaluable help and also for your patience. I feel I'm being rather slow on this learning curve of BIAB.

Using the F5 I muted each of the instruments one by one (interestingly the melody was played by a piano although piano was not listed) and I found that by muting the "No Patch" then the chords will play but not the melody. Great breakthrough and so helpful for this beginner.

I'm trying to make a backing track for Danny Boy to accompany me on the chromatic harmonica that I am learning to play and with your help this should now be achievable.

Thanks again
