First i want to say that i’m very new to linux.
I’m using Ubuntu installed Renoise the same way as in the help files.After that i installed a LADSPA plugin pack that comes with Ubuntu. The plugin directory is ok (/usr/lib/ladspa) .When i start renoise i see he is scanning the directory and the files (xxxx.so).But he doesn’t find the plugins.I know there are LADSPA plugins in that directory because i know Hextor 
I hope i`m a little bit clear
Thanks

hi,
try loading Renoise from the terminal, by simply entering the command:
renoise
from the terminal
this should give you more information about your problem with the plugins; for exmaple, here it is a report for a plugin which cannot be used inside Renoise:
Renoise LOG> LADSPA: Trying to instantiate /usr/lib/ladspa/fmod_1656.so:fmod_fcmc_oc...
Renoise LOG> LADSPA: Found plug 'fmod_fcmc_oc'...
Renoise LOG> LADSPA: Plugin 'fmod_fcmc_oc' has no Audio outputs. Won't use this plug...
With all the Ladspa plugins i get this error
Renoise LOG> LADSPA: Instantiate FAILED (failed to open the DLL file ‘/usr/lib/ladspa/fmod_1656.so: wrong ELF class: ELFCLASS64’)!
this means you are using a 64-bit version of Ubuntu. Since Renoise is not available as a 64-bit application, you should install it on a 32-bit environment.
Renoise itself can run as a 32bit application in a 64bit environment, but some things such as using a 64bit plugin in it are not possible.
I suppose you have installed Ubuntu 64-bit because you have an AMD64 processor. Well, actually, you can use the i386 as well with no problems, so the best way to solve this would be to install Ubuntu for i386 processors, but I understand this can be annoying.
I downloaded the 32bit and it’s working now Thanks!!
