I like LMMS but the funny thing about it is that some of the essential features (such as extrrnal VSTs) don't work on Linux (unless you set it up on wine, which has it's own issues).
I used LMMS for Windows in Wine for ages. Now using on Ubuntu 16.04 compiled from source linking to libwine. Works fine, I'm not at all clear on what bit of Linux use is supposed to be hard.
