Yeah it makes good sense.. very simple once you sorta see it properly.
Just one favour which may help people to find sumin specific.. maybe seperate the formulaes in modal groups! for example:
Major modes
-------
harmonic modes
----------
Melodic modes
---------
Etc if you know which formula's are the modes of a key.. cos i want to learn the melodic modes but cant quite see where the melodic modes ends in the list.. lol sorry

:P but im sure u understand what i mean right ?
