If you want to change the velocities of a recorded track (e.g. Melody track), inside BB, you could do it as follows.
First [menu]-Melody-Edit Melody- Change Level ... input 127, which will increase all levels by 127.
Since 127 is the max, they will all be ata 127 now.
If you want them lower, do the function again with a negative number.... -27 would put them all at 100.

Have Fun!
