Hi All
1 Question is I have 2012.5 edition of band in a Box ,If I upgrade to 2017 or 2018
Band in a box ,do I erase 2012.5 or does the newer add to older if that makes since ? 2 And also if 2012.5 works on my computers will 2017 or 2018 work as Smooth

It will update the C:\bb folder with the newer version and create a backup of 2012.
It should run fine on all PCs.

Part one, just add. Most of us install new versions over older, to keep any custom styles and bonus pacs.

Part two, probably. The demands on computer resources of the last few versions are somewhat greater. There are some settings to consider if you have any trouble.

Before I bought BB2017UPP I had the use of someones 2008. ;-) I thought it was very clever and would suit what i do. However when i got the new one I couldnt believe how far it had come. So much more and all those Real tracks in addition to midi ones. Word of warning. Im glad I stumped up for the Ultra pack to get all this lovely stuff. Buying say tge Pro might disappoint in shortage of Goodies.
Me? Cant wait til 2018 comes out.
