#20 Make it possible to select certain musicial scale

[grammo]

Would be nice if you could load a certain musical scale, which enables only the keys of the scale. Maybe it could support a certain scale format which you see in synths I guess, which you can load.

Not sure how to do that without changing the display (and recording) completely. If I understand right that would be a display containing only the notes part of a harmonic chord for instance. And I think the only way of interacting with this would be to remove the lines that are disabled.
I'll give it a thought.
