NI B4 working fine here on jBridge with CB9.5.1.
I have a slight niggle with it. When I open a new instance of B4, I get no audio at all from the B4 until I touch one of the rotary knobs on the B4 interface - Reverb, Drive of Bank - then all is fine for the rest of that session.
If I record the B4 as midi, closing and reopening the project works fine and the B4 plays OK.
It’s only on the first new B4 track addition that this problem exhibits itself.
Never been able to get to the bottom of this, including filing a bug report and talking to the jBridge author about it.
I still use B4 simply because it sounds so good, and I also have the Bohm hardware controller for it too.
Cheers,
