i like the recently suggested new hints. i'd like to add the
following, which would allow hosts to do the right thing with
both SooperLooper and SC4, which are the first (only?) LADSPA plugins
to have control output ports, but use them in very different ways. its
almost impossible as it stands to build a GUI for them both that does
them justice.

/* Hint LADSPA_HINT_OUTPUT_METER indicates that the value of output
control port is likely to be most meaningful to the user if
displayed as a meter. Can be combined with LADSPA_HINT_LOGARITHMIC
if the meter should use a log scale (e.g. dB).
*/
#define LADSPA_HINT_OUTPUT_METER 0x??
/* Hint LADSPA_HINT_OUTPUT_VALUE indicates that the value of output
control port is likely to be most meaningful to the user if
displayed as some kind of numeric value display.

#define LADSPA_HINT_OUTPUT_VALUE 0x??

I dont like the wording of this, if the scale is dB's then it should
output dB's, I see what youre getting at, I just think is ambiguous.

How about:
... Can be combined with LADSPA_HINT_LOGARITHMIC if the meter would be
more usefully rendered with a log scale, eg. to show a frequency.
not really clearer, but it aviods the dB example.

The sum, product and branch plugins in 'blop' have control outs, too.
They're trivial though, and their purpose isn't the same - they're
pretty useless on their own.

METER hint: Is this the same idea as the informative/data port
distinction that Steve mentioned? I'm starting to see the need for this
for similar reasons as for the CONTINUOUS_CONTROL hint (improved
automation). I've not used Ardour, though (don't have the need or the
hardware, yet :), so I'm not sure what it does with control-out ports
right now.

Why have both? Couldn't the absence of one imply the presence of the
other? And if there are both, it also implies that there are third and
forth states of both and neither.

I think there is meter and/or text (ie. both if ou support both) makes
sense, and neither, ie. this isn;t menat to be rendered.

i don't think that both makes sense. i agree with taybin that just
"meter" or "value" as a flag will do. the underlying difference, i
suspect, will be between output control ports that are computing
"meter-like" values internally, and those that just show some kind of
state.
