#1. Save song with patches etc This is under the save options.
#2. Allow patch changes at any bar.
As far as #3 is concerned we are USERS.. Nothing to do with pg music but once in a while they come here when we argue about Yanks or Mets.

#4. Band in a box will be updated tu 2012.5 within weeks. You are thus 10 versions old, any many of us are, and I speak for myself and one other to be named later who are too old to remember that version.
This software is intended to be a backup band for someone who plays something or sings to be a baNd instead of hiring one.
So
I guess you bought or downloaded a pirate version. Now if you got this from uncle Jim after his funeral call pgmusic with his name and address and I'm sure they will give you a deal on an upgrade price, I'd get half off that ten bucks discount because I was dumb enough to spend 10 mins touch typing this in an iPad keyboard.
