Hi Oli, too funny, my intention was to sent it to Ubuntu Studio devel mailing list, I send it by accident to this list. I hope that somebody from Ubuntu Studio devel has got experiences with audio apps and this approach. Thank you, for the summarized explanation. I still will send a request to Ubuntu Studio devel and I'll add a link to your explanation ;), or simply forward this reply.
