5 string bass and 7 string guitar – no low B sample; SoundFlag options?

Hi there! I've found that there is no samples for the low B's on those instruments in the new MuseSounds library. Is it known issue and will be resolved or should we just stick to the old MS Basic library that works?

And will there be available SoundFlag options for bass guitar? Switching to slap or pick sounds for example.

Thanks!
