Yes, I agree.  There's always scope for stuff to be even better, 
and this too could be even better.

It solves my immediate problem, though.  I want something I can 
compare against a facsimile original (and other candidate 
sources), and then play from (on a bass viol in an obscure 
/scordatura/), rather than something to publish for others.  This 
meets both those needs.  Believe me, it's _much_ easier to read 
than the original.

Thanks again.  All the best.
