Something that was suggested for GMPI, and might be
applicable for LADSPA
is a convetion where port names can be written as paths, eg for a delay
line you might have
"delay/base delay (ms)"
"delay/feedback (%)"
"lfo 1/ammount (%)"
"lfo 1/wave"
"lfo 1/frequency"
"lfo 2/ammount (%)"
"lfo 2/wave"
"lfo 2/frequency"
this would allow the host to group the controls logically when building
the UI, eg. tabbing them, and friendlier OSC reflections of plugins.
Steve, you will be surprised, but the grouping information looks like meta
data to me. I would have no objection to place this in the RDF extension.
Recently I got a feature request for ams regarding tabbing of LADSPA
parameters and this would indeed be a useful feature.
It would require that lexical /'s be escaped, but
other than that it
should be transparent. Its only worth adding if hosts would implement
something using it though, as it would cause a bit of disruption, there
are about 30 exisiting ports with /'s in them.
Hosts could check the LADSPA version number.
