Is there a way to boost the base velocities of the super-midi tracks?

I occasionally use them to replace midi tracks in my songs, but they always sound too quiet. I can change them using the mixer window, but even at max, they are overpowered by midi and real tracks. I have also tried modifying the volume / velocity in the style without success.

It may be just my hearing, but they do sound louder if they are on the soloist track rather than 'strings' for instance. They are a great improvement on the basic midi tracks.

I am using BIAB 2013
