secondary generator definition

there was a need to supplement the definition of "generator",
which my Dictionary had as a generator of a scale, with a
secondary definition describing the generator of a kernel.

Gene, if you already posted your definition of "generator",
i'm sorry i can't recall it now.

this is what i added:

corrections, additions, etc.

what does this have to do with the definition of 'generator'??

I've been using "generator" in its meaning from the theory of finitely-generated abelian groups, in which sense both the generators of a kernel or the generators of a temperament are generators.
