For a beginner if you ask me I would suggest you to go for Gargeband and then slowly move towards more advanced DAW like Reaper, Ableton, Logic Pro X, etc. It is simple to use and has an easy interface with lots of in-built instruments and mixing features.
I am currently using Reaper on my windows system I wish I could use garageband on my windows system but it is only designed for MacOS right? Or is there a way to run it on Windows?
