I spent some time the other day browsing around looking for free VST
plugins.

There are quite a lot of them, I'd recon somewhere around 50, maybe 100
if we dig.

I thought it would be a good idea to confront the developers in all
friendliness and ask them about the possibility to port their
algorithms to LADSPA.
Should we not try and send them a nice query whether they would consider
porting (or some of us doing the actual work) their plugs to Linux, on
behalf of the LAD community?
I can't find any reason why they wouldn't agree, their plugs are already
free.... especially if we offer to do the actual porting work... (Okay,
the plug might be written in poorly documented visual basic.... but then
we don't want it ;-)

Some of these plugs may not be very good, but some are excellent, and do
fill holes in what is available right now in LADSPA.... reinventing the
wheel might be fun, but it takes an awfully long time...
