Hi,
I have installed them by executing the script “linux-install.sh”, that is from a terminal with instruction “bash linux-install.sh”. This script simply copy the single plugins folders into hidden folder ~/.vst3.
Then I have started Reaper, imported an audio file and used them as whatever else plugin. Of course to use them in full mode I have donwloaded from Ircam forumnet site the activation-key and followed the procedure for activating the plugins (I have annual Forum Subscription).
I hope I have been clear. All installation procedures are explained also in the manual, at PDF page 2.
I have tested automation, too, it runs, the only problem I have until now is some crash in using surface filters, but I think it depends by my hardware configuration and by use of Gnome3 as deslkop manager.
Good Luck :-), ciao
Fabio
