Perform sounds weird because key layout?

Is C-C1 a common way to look at a keyboard slice and I'm just doing it wrong?

Yes

Is there a way for me to make the layout A-G?

Not at this time. But they do provide you the ability to raise and lower the octave. Not ideal, but manageable.

Alternatively, I have heard that midi controllers can be used. Purchasing a 3 octave (37-key) midi controller keyboard would probably greatly improve the experience.
