I mostly learned on Pro Tools, so I got used to it. I liked the GUI, and I learned tons of keyboard shortcuts. When I switched over to Reaper, that’s one thing I didn’t care for and found challenging was the GUI. It did seem a bit clunky to me, but over time I have adjusted. I even tried a Pro Tools theme in Reaper but it didn’t help much. Some cool things about Reaper, though they took some getting used to, are the numerous controls with mouse manipulation and mouse modifiers plus the ability to create your own keyboard shortcuts and layouts. While the customization options are incredible, after coming from ‘stock’ Pro Tools where most of those things are locked in it was a bit overwhelming. I had to settle down and just learn the DAW thoroughly before making tweaks to it.
