Bass fades out at end of song?

As one of my songs is nearing the end on my BBM, (Can’t remember which one) the bass fades out like the recording. I have seen midis do this but I never heard it happen when it transfers to the BBmanager. Not sure if it does it on the BB Pedal. I didn’t think the Bass had the ability to change volume with only one sampled volume/velocity. Unless this is a result of the newer kits with the quieter bass.

Any ideas?

I have the same question about volume? For me it happens on the pedal for proud mary OP.

if you look at the midi you’ll probably see the velocity getting reduced as the song ends

I had ‘one’ w reducing velocities …thought I’d use it …but, it never reduced sounds. Interesting
