I think theres some confusion about what the meta- in metadata means, it

I dont think that scale markings, / enumerations,
defaults and units are
logically connected to the same extent that upper and lower bounds are.
That is a matter of opinion of course.
Well, for me ENUMs on an integer param that maps to a multiway switch, a set
of radio buttons or a menu are not 'meta'. Without them you have *no* idea what
the switch is doing, so they seem IMHO as essential as Min / Max on a slider.
Same for TRIGGER, the host needs to know this, but then I suspect most triggers
would never be in a GUI but rather external or from another module. Scale points on a floating point param are an entirely
different matter even
if they could be mapped to a similar data structure - that's a coincidence and
doesn't mean anything. Separate unit strings are, for me, a luxury. I agree
I disagree: if I have a control thats "wave, INTEGER where 1=sin, 2=tri,
3=sqa, 4=saw" and one which is the same less the INTEGER hint (ie. it
crossfades) then the enumeration points are no less importanti in the
non-INTEGER case.
that both could be in the RDF only. And other than
AUDIO / CONTROL which are
not compatible at the 'physical' level, I think there should be no port typing
in LADSPA.
I agree about no port typing.
The MOMENTARY hint is not (should not be) typing though - its just a hint
to let the host build a useful UI. There are use-cases. Ditto for
RANDOMIZABLE.
As to defaults, the current system is limited, but for
me it is sufficient.
The only thing defaults should be used for is to make sure the plugin start
in a sensible state. Anything beyond this can become a preset, if required.
I understand where you're coming from here. There are a few cases where
the current system fails (not many, and not seriously, but they are
there).
