Been there, done that, hammer!
My take is basically ALL arrangers have things that are a bit odd at times. My G70 was a particular culprit
in this regard. OOTB, it puts you off a bit, but once you get under the hood and tweak, it stands up
against most newer arrangers.
One thing that Roland's Makeup Tools is exceptional for is tweaking 'on the fly'. Basically, I can play a gig,
hear a tubby bass part, or too quiet snare, get to the parameters for the problem in a minimum of button
pushes WHILE THE SONG PLAYS, fix the problem then hit 'save' at the end, and that is IT. Problem
permanently solved, otn to the next one. After a month or two of doing this incrementally while you
play, you end up with consistent EQ's, volumes, sounds, effects, you name it. And all without
interrupting the act!
Learning to get around this fast on ANY arranger saves a boatload of messing with stuff, essentially FOREVER
if you have to do it with external gear. Only something that stores your tweaks will fix the problems
