I use reaper day in and day out for sound design and composition. It truly is more customizable and powerful than any other DAW in a few ways. That being said, Studio One smokes reaper in its weakest area…midi (e.g piano roll, expression maps , etc)
I still recommend Reaper because it’s so accessible and powerful. Just hope Cockos invest in midi feature like Cubase and Studio One have.
