Acoustic Feedback-NO Sound on Velocity change by Mouse Wheel

Hello! There’s a serious bug in Piano Roll v 7.0.1 - when I drag note velocity by pencil tool in controller lane - it does produce acoustic feedback, but if I change velocity using a mouse wheel within INFO LANE (that always worked in 6.5) it works ONLY SOMETIMES !!! don’t even have a clue under which circumstances it works - just works sometimes… mostly DOESN’t

I have the same problem!!!

Anyone can help ??

Windows 8, Cubase 7.0.2 64bit
