It sounds like there is a lot of prep time involved - maybe a little too much. Do you think that in the end it is more of a time saver (not having to deal with scanning and printing sheet music and keeping it together) or a time waster (programming the MPP and doing a lot of tweaking)?
I do a lot of nursing home jobs where the seniors are practically brain dead, and it's great to bring some sheet music to practice new material. I think the MPP is perfect for those gigs as well as home use. Occasionally using it at a high profile gig is probably good too.
Anyway, congratulations. I won't be following suit, for price reasons, but I'm happy that you're happy.
It doesn't seem like there is much new at Winter Namm anyway.
