The answer lies in pgmusic trying to fulfill the many wishlist requests, I think.

But the two programs really are complementary.

BiaB is first and foremost an Autoaccompaniment software.

RB is first and foremost a Multitrack Sequencing program.

While they cross in certain ways, duplicating *every* way would mean that both programs would be identical, thus one would be superfluous.

It takes time and practice with these excellent programs in order to understand things and bring out the best.

Important part of the above statement is that you should always endeavor to "have fun" with these things while working with them and learning what can be done. In other words, try to avoid frustration by doing just a little bit each day.

These two programs are much like learning two new musical instruments.
