On some situations this (set_parameter()/get_parameter()) is not that bad,
as you can use set_parameter() to do precalculations.

First looking at the VST2.0 API (huge!) and then looking at the LAD
archives, well, it'll take us a few decades to reach an VST2.0 superset
we are all happy with. Sorry for sounding pessimistic, but as far as I
see it, we're back to square one. I've implemented both LADSPA and
VST1.0/2.0 (although can't publish this) hosts, but now it looks
like that neither of them is going to be used.
And one crucial question, whose going to write all this functionality?
Those of us, with the biggest plans ;), are among the most busiest people
on this list. If I need to have some of effects, I need them
now. Not because I'm impatient, but because there's desperate need for
*real*, *existing* audio tools for Linux. If these effects are not available
as plugins, I'll just have to write them myself. If there's no commonly
accepted plugin API available, I'll write them as native effects.

Btw; no sign of GPL licence on ladspa.h ...? What's the deal this this?
I'd really like to publish ecasound's current LADSPA support (already
in CVS).
