@juneonline @itsfoss Reaper can be intimidating, even for me, and I have been using it since version .98 and it is now on 7.4 something. When I switched to Linux about 10 years ago, I tried other things, but I was SO happy when they made a Linux version. I find that whenever I am confused, the online community is very helpful and in dire cases, there is always a video. Bugs are often fixed in days and I have had issues addressed by Justin Frankel, the developer, himself.
However, it is not at all like Ableton, so it might not be for you. I think that most Linux musicians who are not using Reaper are using Ardour.
