I have had a scout around to see if this was mentioned anywhere. It’s not a major problem but I use Fedora 15 64bit and Renoise 64bit is looking for DSSI’s in /usr/lib. Simple fix is to just symlink /usr/lib64/dssi to /usr/lib/dssi and all works.
I thought I should mention it as I have been aware of the issue since I first looked at Renoise but wasn’t sure if /usr/lib64 was common across all Linux distros. And just recently I reloaded all the DSSI’s and couldnt figure out why they weren’t loading again.
