Reaper, the recording software I have been using for years, now has a native Linux version. It is still in beta, but it works pretty well in Linux Mint. My computer is still dual boot, Win 7 and Linux, but I rarely go into Windows. I have lots of great amps sims and drum software in Windows, but Reaper comes with a lot of usable plugins and there are a number of free ones that work in Linux that I have been learning about. There is a learning curve, however.
Here is a track done in Reaper with Reaper’s amp simulator, Dragonfly reverb, and Drumgizmo playing a midi drum loop. The two guitar tracks were done with my new Casino, direct into the Steinberg UR44, my audio interface.
This was done quickly, but I kind of like it.

Groovy! I like it.
Craig suggested that I alter the progression a bit, replacing the B7 chord in part A with a B min and the B7 in Part B with a Jimi Hendrix approved B7#9. I’m thinking about it.
