Kent (and all the others).
Thanks for all the advice, but I haven't really made any progress in this point.
I (usually) don't use an external MIDI keyboard. I want to use the Garritan sounds exclusively as better sounds within BiaB (without transferring everything to a DAW).
I already read that the Garritan samples put the volume on the mod wheel. But that doesn't help me within BiaB. The Aria VST player has a mod wheel, but this unfortunately does not work as a volume control. The Sforzando VST Player does not even show a mod-wheel.
And yes, Options - Preferences - MIDI Options, "Zero the ModWheel Controller when stop pressed" is unchecked.

I also tried to put a CC 7 (127) into the MIDI track via #, but even that doesn't change the low volume. And I don't want to buy the Garritan JABB 3 package without knowing if the samples are too quiet.
The JABB-3 is advertised on the BiaB website as an third party sound extension to BiaB - how do other users solve this volume problem?
