Hi Vince.

I believe you could master the touch screen on the G70..The layouts are the same for the style selections and the tone selections..Two columns of five..

The User programs are also similar, with two columns of four...Each have multiple page selections on the lowest portion of the touch screen..

One great feature..the G70 will beep when you make a proper touch on the screen..I think this will aid you in touching the designated areas..

The tone and style categories are dedicated buttons that will be easy for you to navigate.

The numeric pad has a dial you push and the numeric pad pops up on the display..it is arranged as a telephone dial layout..

Vince I have tutored a blind friend years ago to learn the very complicated Roland G800..and I am totally amazed how he mastered the G800..I believe the same can be accomplished with the touch screen on the G70..

There is an area to either side and across the top and bottom that you could put raised markers to find areas on the screen..as a crossword pattern..

There are some software programs at Roland-arranger.com that may aid you for programming user programs etc..

I am confident you could get around on the G70...with the learning skills I have seen in the past, working with my friend Jack..

When I worked with jack, he recorded my voice explaining each feature, default pages, clicks to get to each page etc..After he applied this learning process..he was as capable as I was with vision..Good luck, Fran
