You're confusing two things: unit and reference point. The second
you have only on a log scale, for example if you use dB you need
to define what 0 dB means.

The unit here is 'octaves'. The reference point is not a property
of any port AFAICS. It could be a property of the plugin: the
frequency it is set to when all control inputs are zero.



A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
