Hi again Katja, I just read through it. Couldn't find anything about having the GPU process some audio. It's really mostly about why it's a bad (or good) thing to keep the GPU closed-source (at least that's what I understand [?]).
So I guess there isn't must we can do on our own to access the GPU. But then, what can Eben and his team do about it ? I'd like to know what answer we can give him. If he says "just waiting for an application like this" I am assuming that it must have aroused his interest somehow. And I believe that it would be great if people in the Pd community got involved. All I can provide is some testing, but others could contribute more (if i'm not mistaken, Miller Puckette did a great job fixing the analog out for instance). I think we should try and play a part in the development of the Pi. And if we're lucky we'll finally have that Pd box people have been dreaming about for years.
