I have both Reaper and Cubase 7.5.20,
Cubase is work of art. Reaper is functional but requires a lot of custom UI config to look decent.
All I had to do with Reaper was download the White Tie Imperial Theme.
White Tie : Imperial - REAPER theme for large monitors
Check it out if you haven’t already, (It has been available for quite some time now)
It looks absolutely amazing! Professional, Functional, Solid.
Worth a look if you haven’t seen it. The swiping of controls to enable
track arm, mute, solo etc. on multiple tracks is also very fast and works perfectly.
