Only disagreement with that, for honesty's sake, is the voice editing, Lee.
Roland's voice editing parameters are very barebones compared to most arrangers. However, having them all on the sliders under the correct parameter name on the screen (no offsets on Roland's between the parameter and the slider

) is very convenient and quick to adjust.
Plus, of course, on Roland's, there is no 'User Tone' bank, so you either have to use the Session Manager software, or recreate your favorite edits when you create the Registration (UPG). Every time...
Style and SMF editing, I don't see how you COULD improve the Roland's Makeup Tools much, but personally, I think Roland have a long way to go to catch up in the voice editing and storing department....
JMO....
