George, Is the G70 using the same sound engine [XV/JV] as the Fantom, instead of the SC/GS sound engine in the previous G's and VA's?
When you get time can you compare some common patches as you did the piano patches..particularly the "soft brass"[the G1000 is better than the Fantom X..
Steel guitar 2, choir and scat[VA is way better than the Fantom X]...
I have a Fantom X, and I can get a better feel for the G70 patches with your comparison...
Actually , I am hoping Roland retained the same sound engine {G and VA] annd just added an additional bank of G70 sounds, like the previous models...I prefer many G1000 patches to the counter sounds of the Fantom X..

The "soft brass" example has the fat sound we only got with the JX10 and D70....can't get the same thing from the JV/XV gear..
