  Hi!

 I've been trying to implement LADSPA send effects in my latest playtoy.
 I've had some problems with freeverb though. It simple doesn't produce
 any output (execution seems to be veeery demanding) until I specifically
 set some of the parameters to non-default values. I thought the default
 port parameters would take care of this, initializing the plugin with
 sane values to avoid things like these, but perhaps I'm doing something
 wrong... Has anyone else noticed anything similar with freeverb?

 Are you specifically setting the default values?  They're just hints,
 the host still has to set them.  Plugins don't initialize ports to
 default values IIRC, they will be garbage until you set them to
 something.

 -DR-  
 Yes, I'm specifically setting them, with the values provided by the
 hinst. Using the hint-values, nothing comes out of it and execution is
 really slow, when using some "personal" values, things mysteriously
 begin to work.

 Looks like the default values for freeverb have both dry and wet gain at
 0.  That would explain it, eh? :)

 -DR-

I guess it might have something to do with the whole thing. And I don't have a problem
with a plugin producing no "pluginnish output" when it's launched, using the
default values, but... Even though they're merely 
hints, the freeverb init-settings (yeah okay, they're not init-settings, but
"hints") really aren't nice to the system, and I don't like that.
