I dont agree

Theres something about how the keyboard just shows one octave and yet the notes your iding range many octaves that doesnt jive with me. So, c5, say, has the same answer as c2.

The sharps and flats also annoy me because, while technically e flat and d sharp are the same, e flat is generally favored. Yet both are equal here.

The whole addition of making your own modes is so-so too. Seems cumbersome to me not just to be able to train on bass clef or whatever.
