This looks like a straightforward linear transformation issue to me
(like Fahrenheit to Celsius). Add 50 to all input values, giving you
values in the range 0 to 100. Then scale them into your 0 to 12 range
by multiplying them by 12/100:
>>> for n in range(-50, 50, 3):
... print n, n + 50, (n +

Anyway, I need to convert various values ranging from around -50 to 50 to an 0
to 12 range (this is part of a MIDI music program). I have a number of places
where I do:

There are multiple interpretations of the operation, and not all
languages behave the same w

Could be normalising, could be scaling.

x = x % 12
should be the same as the above. But are you sure that's really what
you want?
