If Ableton for some reason added Linux, I'd hate to be in tech support. Just getting all the audio and device drivers to work under Linux, if even possible, would be a nightmare. Is the graphics library that Ableton uses even available in Linux?
it was not very difficult to install my m-audio fast track pro under linux with wine.
and i think the graphics-library ableton uses in windows is not available under linux. but it's also not available under mac
and of course there are not many musicans using linux. but why? because steinberg, ableton and co are not supporting linux. why should you use an os when you can't use your important programms on that os?
i'm really sure that there will be more musicians using linux if ableton would support it. because windows is bullshit, a (good) mac is for many to expensive and linux runs on a pc and is free.
i own live 8 but i evan would pay a little bit for a crossgrade to live 8 on linux.
