The default values that a control port may hold. For audio ports, use DefaultControlValue::None.

Variants

`Minimum`	Equal to the `lower_bound` of the `Port`.
`Low`	For ports with `LADSPA_HINT_LOGARITHMIC`, this should be `exp(log(lower_bound) * 0.75 + log(upper_bound) * 0.25)`. Otherwise, this should be `(lower_bound * 0.75 + upper_bound * 0.25)`.
`Middle`	For ports with `CONTROL_HINT_LOGARITHMIC`, this should be `exp(log(lower_bound) * 0.5 + log(upper_bound) * 0.5)`. Otherwise, this should be `(lower_bound * 0.5 + upper_bound * 0.5)`.
`High`	For ports with `LADSPA_HINT_LOGARITHMIC`, this should be `exp(log(lower_bound) * 0.25 + log(upper_bound) * 0.75)`. Otherwise, this should be `(lower_bound * 0.25 + upper_bound * 0.75)`.
`Maximum`	Equal to the `upper_bound` of the `Port`.
`Value0`	Equal to 0 or false for toggled values.
`Value1`	Equal to 1 or true for toggled values.
`Value100`	Equal to 100.
`Value440`	Equal to 440, concert A. This may be off by a few Hz if the host is using an alternate tuning.
