3.3 Multiple MIDI controllers
Together with the BCN44, several MIDI controllers can be connected to one another in order to construct a
broad control setup. Your setup can be expanded with the members of our BEHRINGER B-CONTROL
series (BCR2000, BCF2000 and BCA2000).

Your B-CONTROL supports all kinds of MIDI messages, which are explained below:
Program Change Messages and MIDI Bank Select:
Program change commands are used to call up programs or presets on the MIDI devices connected to your
B-CONTROL. There are 128 program numbers available for calling up presets. For devices with more than
128 presets, you can use the Bank Select function, which lets you select a specific storage bank
before
sending a program change message.
Control Change (CC):
Control Change Messages let you retrieve and automate many parameters and functions. You can allocate
individual control elements (controls, buttons etc.) on your B-CONTROL to CC messages. Because both
buttons and knobs can be used, you can control controller values either statically or dynamically, all in real
time.

Standard MIDI Control Change commands are listed in table 6.5 in the appendix (ch. 6).
NRPN:
Furthermore, you can also use controllers that feature no standard allocation, and can therefore be assigned
in many different ways. These are called NRPN (
N
on-
R
egistered
P
arameter
N
umbers). NRPNs are broken
down to MSB (
M

S
ignificant
B
yte) and LSB (
L
east
S
ignificant
B
yte) in order to achieve a higher data
resolution. A low resolution becomes apparent very quickly, particularly during fader movements of a mixing
console. A resolution of 7 bit (= 128 values) makes for rough and bumpy level jumps. By dividing up the data
into MSBs and LSBs, you can accomplish 14-bit fader/encoder resolution, corresponding to a subdivision
into over 16.000 steps! In addition to NRPN, there are also RPN (

umbers). RPN
commands are defined in the GM (General MIDI), GS (Roland
®
) and XG (Yamaha
®
) MIDI standards .
