I have hundreds of songs written out in Band-In-The-Box. When I used my laptop on stage I could transpose as needed for singers, horn players, ect... I have upgraded to the iPad, downloaded the Band-In-The-Box app, and transferred all my songs to the iPad. However the transpose button on the app does not work. This makes all my previous work and the Band-In-The-Box app useless to me. Oh well, I won't be going back to a laptop on stage. Please let me know if/when the transpose button will work. I will buy/upgrade/use Band-In-The-Box again at that time.
