B4 

 
The US-428 Control Panel now includes the addition of another Control Surface Protocol in the 
drop-down box: "Native Instruments B4", for mapping the US-428's control surface to Native 
Instruments' B4 virtual organ. (NOTE: A demo version of the B4 can be downloaded from the  
Native Instruments website at 

www.native-instruments.com

). 

 
NOTE: The following setup procedures must be done with the B4 running as a standalone 
application, rather than in VST Instrument mode.  
 

 
AUDIO SETUP: 
 

In the B4 system menu: 
 

• 

Under "Audio Port" choose ASIO 

• 

Under "Audio Settings" choose "ASIO US-428 (24 bit)" 

• 

Also under "Audio Settings" use the buffer size slider to set a value that is EQUAL TO the 
value chosen in the US-428 Control Panel. Ideally, best results will be achieved with a 
buffer size setting of 256 to 512. 

• 

Note that if you change the setting in the US-428, you will have to update the setting in 
the B4 the next time you start the program. Failure to do this will result in noise. 

• 

Under "Audio Routing" click the Audio In "All Off" button, and click the Audio Out "Default" 
button. 

 

MIDI SETUP: 
 

• 

Under "MIDI Settings" make sure that you've selected the proper MIDI IN ports. (For 
example, if you're feeding a keyboard into US-428 MIDI In 1, choose: 

US-428 Port 1 

US-428 Control 

 
(You MUST include "US-428 Control" port, or the faders and other surface control will not work) 
 

• 

Also in this dialog, select 

Upper manual = Channel 1 

Lower manual = Channel 2 

Pedal = Channel 3 

Leave MIDI Input filtering disabled.
