Dennis, thanks for the implied offer for help. Yes, I understand that the G70 is a very European keyboard and there is a lot of help across the pond.
Fran, this is all your fault

. I like your comment about being familiar with the OS thru previous arrangers. That certainly is a BIG plus.
For Diki, Tarkington and others - any thought that I would just go into this arranger stuff lightly shows a lack of understanding on your part. I could play this thing all night without a hitch or complaint, but then I'd be settling for what is THERE. I'm upset over what isn't there or at least easily seen or found. As Fran points out, a lot of this stuff is learned over years of working within the Roland OS concept. So maybe he, Diki, Miden and others have a better understanding of the in's and out's of this monster than someone like me who hasn't had a Roland arranger. I incorrectly assumed that my experience with Roland synths would make this chore easier - not the case. I believe that anyone without previous experience with this Roland arranger OS would be asking the same questions I have just because the info is not readily out there IN THE MANUAL. Yes, I'll give you the fact that maybe I need to start using and saving UPGs; that seems key to saving what I DO want, but there are questions that don't apply to user settings, like global settings that aren't there and adjustments to parameters that should be there, but don't seem to be.
The G70 is one helluva keyboard; it has features that I will never need or use and that's OK. But what frustrates me are the features I assume are there, but I can't find. I give you G70 gurus credit for being able to rope in this mustang and only ask that you try to understand that there are others out there who have simple questions that require complicated answers, and you probably have the answers without even realizing it because you've already been thru the learning curve. So help us out instead of telling us to READ THE MANUAL and ASK QUESTIONS on other forums. What you know is NOT in the manual. What I want to know is NOT in the manual, I think.
After sleeping on my rant, I've decided to start posting questions about the G70 here and at Roland-arranger.com. I'm hoping I can find out (learn) what I need to know thru that technique.
So I leave those of you who know anything about the G70 with this question (#1): Can I adjust and save "vibrato-chorus" parameters in the drawbar setting? I am not satisfied with the chorus settings, especially C-3.
