Native Instruments B4D Drawbar 2000

MIDI Drawbar controller for your Sampled Organ. Does what it’s supposed to do. Power supply included.

Different sampled organs seem to respond differently to this controller so you may have to tweak the MIDI commands a bit for chorus and vibrato. It’s so great to be able to have drawbars that feel like the real thing.

I don’t have the instructions or box.
Here is Native Instruments’ description:

With the B4D Drawbar Controller, Native Instruments gives you a perfect hardware controller for the B4 software organ, allowing you to control your organ sound with an authentic drawbar feel. The sturdy B4D drawbar controller offers nine mechanical drawbars, 22 buttons, and 2 knobs for intuitive control over the most important B4 sound parameters. The B4D controller's nine drawbars can access any of the three B4 drawbar groups.
