The pitch excursions of the template on word k are scaled by a factor
before the Stem-ML tag is generated. Thus, if
| atype| > 1, the pitch range
of the generated Stem-ML tag will change a lot for a small change
in strength, while if
| atype| < 1, the pitch range
of the tag will be relatively independent of strength.
