Any DAW has a learning curve.
I personally use Ableton Live Lite, as it was free with my Focusrite Scarlet 2i2, and I’ve not reached it’s limitations for what I do.
I did briefly try Reaper, but couldn’t quite get my head around how it works, and the purchasing nag pop-out annoyed me.
The key things to get recording in Live, is ensure the audio interface is configured correctly.
Options → Preferences
The main thing is selecting the correct Driver Type, and Audio Interface.
The rest should configure itself automatically, and the defaults should be more than good enough for home recording.
To check it’s working, plug in a set of headphones/speakers to the interface, and click the Test Tone button.
Once that’s done, when you open Live, it should default to the vertical screen-
Plug your guitar/mic in, and check the signal shows up on the little channel indicator-
(note the little green bit next to the 1 )
Now if you click the Arm Recording button, the signal will show on the level indicator-
Now if you hit the record button at the top middle of the screen, that channel will get recorded.
However, I prefer to use the horizontal display for recording, as you’ll see the track getting recorded. These buttons near the top right let you select horizontal/vertical display-
And this is showing a quick sample I just recorded-
If you want to use the built in metronome/click track, set it in the top left-
Just click on the tempo and type in the tempo you’d like.
The drop down next to the enable button lets you configure the basics.
I’d normally suggest a 1 or 2 bar count in (remember anything payed during the count in does not get recorded!), but I was using 4 due to the high tempo I was trying.
Then once you’re done recording, you can save the Live Session (saves all the tracks you’ve recorded, along with Live settings), and/or Export Audio (file menu) into something more shareable (FLAC is the usual option)
And that’s the basics covered.
If you want to find out about more advanced stuff, I’d suggest having a search on YouTube as there are lots of videos on how to use it, but I never found one that explains the absolute basics of how to do a simple recording
