Thanks a ton, man.. Part of me would love to be humble and say "aww, it was nothing", but the truth of it is that it was a ton of hard work in both the writing of the parts *and* the execution...(thank the PTB for ProTools and punching-in!). I've done a lot of crazy playing with Haji's Kitchen and other stuff, but I've never had to worry about helping to appropriately "guide" songs of that length and with that many changes. There was a lot of sweating, listening & re-recording involved, but I'm extremely proud of the songs overall, as well as my own parts themselves.
Thanks for noticing!
To get back on topic, I'm not sure I've really got any advice for you on jumping from 4 to 7. I went from 4 to 5 to 6 along my path, so the change was never that abrupt. I'd say once you get comfortable with how it sounds, just leave the 4 at home & jump right in. You'll probably have to endure the odd bad note now & again, but with me that happens anyway...
I would recommend taking more time to stretch & warm up your left hand though. When I went from the 5 to the 6 I ran into fatigue issues with my left when it came to gigging, so you may have to "feel out" what your hands need for a bit.
Lookin' forward to the new Enchant, man..
