MyJazzBand

A long-time BIAB user, I found this program while searching for an alternative because of BIAB's poor interface.
While MyJazzBand has a clean interface, its features are primative. No styles to choose from or create (apart from the default Swing, Bossa, and Waltz styles), and no melody or/and notation to print out lead sheets will ensure MyJazzBand's destiny in the trash.
Priced half as much as BIAB at $40, it has far less than half, or an eighth of Band In A Box's features.
Spend the extra $40 and just buy the real thing.
