Ok. thank you.
But which deb should I install. There are many deb’s for csound. And I would not compromise my system. So can you - pleace - be more precise and can you show me the right way.
OSC with CSound
I only ever build Csound myself on Linux, but I guess the details are found here:
https://packages.debian.org/sid/amd64/csound/download
Add deb http://ftp.de.debian.org/debian sid main to sources.list and then run apt-get update. When you next try to install Csound using apt-get is should be the latest version.
Ok, there all good Informations. Such like “you should not install csound manually, you should it install by apt-gert”. But there are no Informations which I should do to install the osc-Oppcodes. And I not familiar with such thinks like " ass … to souces.list. But I’m very silly. And I’m very blind. So I hope you will be at this point longer my friend. And I will try to do what ever you say.
