I have used Freeverb a lot in previous implementations of the CMT LADSPA
package and the last version of Ardour I was using was beta 11.1 I
think.
I am using Arodur beta 17.1 now and all other LADSAP plugs, including
those in the CMT package, seem to be working fine but the response of
Freeverb has changed...the reverb time is now very short and won't seem
to adjust beyond a shortish plate type reverb. Before you could get
super monsterous reverb tails if wanted.
Has anything changed in the Freeverb module? Is there something new in
the Ardour package that might be causing this? I notice some new panning
thingys and such.
ANY help would be much appreciated. I tried every other reverb out
there...Tom's (TAP-Plugs) comes close but Freeverb is the smoothest most
realistic I have heard for my needs.
Thanks

Just tried this in AMS 1.8.3...Freeverb is not working in AMS either so
I wan't to exclude Ardour as being any part of the problem here.
I tried TAP reverb in AMS and it works fine.
So what might have change in the CMT version of Freeverb? I origianlly
had CMT 1.15-2mdk.rpm installed. These are Mandrake rpm's...I also
downloaded CMT 1.15-3.mdk.rpm and installed and it is the same thing.
Any one know anything about the specifics of the CMT package of LADSPA
plugs that may be relevant?
Thanks

This is an interesting issue, while it doesn't directly concern me right now,
it's something I'd like to understand better. For those of us who rely on
packages to populate our harddrives, the process of recompiling beyond a
one-shot build is less than trivial. A little more detail in the solution
part of this discussion would really be valuable, as I suspect this is a
thread which may be Googled for by future newbies. A few pointers and
signposts on where to start patching, recompiling and installing binaries
might answer possible FAQs. I'm asking here partly because some of Malcolm's
explanations on other topics have really clued me in, for which thanks is
due :-) ... if you have the spare time / braincell etc...
cheers

You might also be inadvertantly coming up against some "bugs" (the gcc team
doesn't admit they are bugs) in modern GCC compilers with respect to
floating point intermediate formats and potential losses (or increases) of
precision.
If you're using a CPU with SSE (Pentium 3 or newer, or AthlonXP or newer),
try recompiling your binaries with -mfpmath=sse and see if the bug persists.
Depending on the nature of the code, you may gain a measurable speed boost.
The GCC team call this "the most reported non-bug", but I don't really
agree
with them on this being a non-bug.

Yes, it goes by the name of "Eschew bloated distros with bizarre binary
