Trs simple as all products of the brand. In addition to the NI service, is very well done. It does not bug and I feel (non verifies that it consumes little CPU trs.
The design is beautiful and the view without a keyboard is a clever IDE to simplify rglages.

SUITABILITY/PERFORMANCE

The sound is excellent. I just regret the sounds "clean" that remain I think unpeu loading ... but overall it's a Russianness. The Leslie vibrato ... are also excellent. The B4 silent dj quip trs well as presets, the B4II is still better off, even if they were adding a few that are not worth much.

I use it for 4 years (B4 and then B4II). I never tire of it and RPIX is acceptable for this wonderful plug-in.
A purchase Obviously ...
