[Ardour-Users] ladspa plugin

[yvln at free.fr]

 I've tried to use the plugin  ladspa : matrix ms to stereo
in Ubuntu 9.04
Ardour 2.7.1 from Ubuntu repository
and
Ardour 2.8.3 from svn
on both version i get the same problem :
the first chanel goes to both outputs correctly but the second chanel is 
going only to left out instead of going to left and  to right with 
reverse phase
i can't make it work although it works well with jackrack and audacity
