In this guide I explain how to transform a .deb to a .rpm and install it.
We need to install alien
sudo zypper install alien
Download, convert and intall
Download .deb from original website Tonelib GFX (is the ubuntu Experimental).
Go into the folder with the file and exec the following
sudo alien -r ToneLib-GFX-amd64.deb
Now it create .rpm file and you can install with:
sudo zypper install ./tonelib-gfx-4.6-7.x86_64.rpm
Now if you search on you application you can find ToneLib-GFX ready to run.
If you want the vst2 ready to use in your DAW you can find it at /usr/lib/vst/.
Who packet the closed source application think to work on Ubuntu or Debian, but it is not a problem for Open Suse thanks to alien.
Enjoy your music and use Linux.
