support for isomorphic piano keyboard

Your app seems very interesting for a lazy aspiring musician like me and I am wondering if it can work with a single-row isomorphic keyboard such as the Dodeka which has uniformly spaced keys of equal width for all 12 notes of the chromatic scale rather than having 7 uniformly spaced white keys of equal width and 5 black keys (of zero effective width) like the conventional piano keyboard has. From what I have read, you only provide scaling and horizontal positioning of the image of the keyboard and must therefore use built-in knowledge of the layout of a standard piano keyboard i.e. you must assume there are 7 white keys in each octave whereas I am interested in the case where there are 12 white keys in each octave.
