Reaper is good, but Bitwig is much easier to get into.
Also, if anyone doesn't know about Airwave [1] they should check it out for running their Windows VST instruments (or those from e.g. vst4free.com [2]).
What annoys me about music software, though, is the way the authors/companies have special offers which are time-bound. Free u-he VST instruments if bought within a two-week window? Eh? What about the people who already bought the software? Or did beta testing? Or... ?

While I don't do it often, video editing is something that is still lacking in Linux.
I have tried a few options, but none of them feel quite right. There are always strange workflow patterns, or missing features that I think are crucial.
