GENERAL NOTES ABOUT USING THE B4The US-428 Control Panel now includes the addition of another Control Surface Protocol in thedrop-down box: "Native Instruments B4", for mapping the US-428's control surface to NativeInstruments' B4 virtual organ. (NOTE: A demo version of the B4 can be downloaded from theNative Instruments website at www.native-instruments.com).NOTE: The following setup procedures must be done with the B4 running as a standaloneapplication, 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 thevalue chosen in the US-428 Control Panel. Ideally, best results will be achieved with abuffer size setting of 256 to 512.• Note that if you change the setting in the US-428, you will have to update the setting inthe 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. (Forexample, if you're feeding a keyboard into US-428 MIDI In 1, choose:o US-428 Port 1o US-428 Control(You MUST include "US-428 Control" port, or the faders and other surface control will not work)• Also in this dialog, selecto Upper manual = Channel 1o Lower manual = Channel 2o Pedal = Channel 3o Leave MIDI Input filtering disabled.
