13. Ky.FW Key Follow

Key follow defines how a note maps to the pitch of the oscillators.

A value of 100 will map a note's pitch to the oscillator's pitch 1:1. A value of 200 will map a note's pitch to the oscillator's pitch 2:1, and so on.

This parameter is useful for generating different timbres for AM and FM synthesis, depending on the note struck. It can also "lock in" a fixed oscillator pitch for an oscillator by setting it to 0, which is, for example, useful when using one oscillator as a fixed frequency or amplitude source.
