My main complaint is not really about Linux, per se, but the whole DAW, etc., scene: Lack of interoperability!

I have a lot of Cakewalk files from the Windows days. Cannot do anything with them besides play two tracks in Cakewalk-Express using WINE.

I have bought the Harrison Mix Deck (based on Ardour), but I need to be able to integerate MIDI tools for which one of the other really good Linux DAWs work better. And so on ...

In Windows, we do not really have sooo much choice. Maybe the "Big 3" and one chooses one and lives with it. Linux affords much more choice but the choices may be more specialized, have more distinctive strengths and weaknesses.

BTW, this is a professional list. Maybe I am showing my advanced age and sensitivities but in my day, "sucks" was considered an expletive. Do we really need to use such language among our colleagues?
