++votes. Without a per-parameter default value, there's no way to
initialize the generic plugin GUI to a sane state. If you initialize
to some "common" value like 0 or 1, you might have a default that does not
fit inside the specified bounds. Now in ecawave, I currently initialize to
the lower-bound. If not specified, then to the upper bound. If neither of
the bounds are specified in plugins hints, param is initialized to 1.0.
But in many cases, this results in unwanted bahaviour. For instance, if
you now select Steve's multiband-eq in ecawave, all bands default to -70
(which is the lower bound)! Now that's far from a sane default state. :)
