I use MuseScore when composing in the notation method; putting symbols on a score... which has been done by thousands of composers, for hundreds of years.  There is an alternate way of creating a composition:  'sequencing', or "loop-based".

For that method I use the Reaper software package.  It turns a computer into a DAW (digital audio workstation).  Reaper is free to download and use, and is becoming very popular for amateurs and professionals alike.  (RPP = Reaper source file)
