In the past I had favored Jammer pro ( version 4 ) over the BIAB version that was released during the same period ( BIAB 8 or 9 .. ). BIAB 8 had more features, but J pro 4 made it much easier and faster to alter styles and come up with original material to work with.
Jammer 5 has added new features, including the ability to use and alter midi data for stylemaking, but the OS has become cumberswome to me, and I think I now prefer BIAB 11 over it. I think BIAB 2004 should be a nice upgrade over version 11 ( which is now 2 versions old..there is a v12 ) , and I believe the reverse is now true, meaning that the current version of BIAB will allow me to make better original backings and style parts in an easier interface than Jammer 5 does. BIAB is also packed with a ton of features vs Jammer. Looking forward to working with it.
