dave, "powerful" is about engineering quality. a standard (even if it is
shoddily engineered) is good if i can adhere to it and be sure my stuff
will work somewhere else.

these issues are *orthogonal*. don't pee your pants, i'm not criticising
the engineering part.

what makes a standard successful is *market* *penetration* - everybody
and their grandma implements ladspa because it's simple. implementing
lv2 is harder. there are good reasons for it - it's better in every
respect, except in uptake. there is an entrance barrier to it. you can
ignore it and piss off people who point it out, but that's not going to
remove it.

ardour and other hosts frequently exploding in the presence of
yet-unbeknownst lv2 features?
yeah, in theory, they shouldn't do that :)

or try to make sense of the swh gate plugin in the absence of

i'm not talking about mechanism. the mechanism is fine. i'm talking
about the politics of getting a usable standard out there.

the increased power of lv2 comes at the cost of greater complexity,
which in return slows down the adoption.

your definition of "plenty relaxed" seems to differ from mine quite
substantially :-D

the "standard" aspect of lv2 is not done yet. which is plainly evident
from the fact that most innovative lv2 plugins that show up require
patches to the host in order to work - it's not clear to host writers
what they should implement, and plugin writers can't assume what will
work in any given host. until that changes, lv2 is not a successful
and it takes other skills that software engineering to change that,
which you seem to be a) unwilling to acknowledge and b) lacking.

hence, i'd better give up now. how a person with arguably twice my iq
can so painstakingly kepp missing the point i was trying to make is
mystifying. but it seems pretty pointless to rehash it all over.
