Re: tranpose relative to the last pitch

[Tom van der Hoeven]

Thank you David,

I see you point. With \modalTranspose you can automatically change the 
notes that are within the range of the scale.
But I change the notes based on visual inspection. In fact I colour all 
notes f and lower in red, so that it catch the eye immediately.

If I change a few successive notes I rather place no extra octave 
changing marks on the first pitch. ( the first f after \terts{ )
It is clear that the pitches after \terts{..} might need extra octave 
changing marks because they relate to the pith just before \terts{..} .
So within \terts I want to know the absolute value of the g before 
\terts{...}
