B-CONTROL FADER BCF2000/B-CONTROL ROTARY BCR2000

Control Change (CC):

Control Change Messages are some of the most powerful MIDI

messages. Using them, a vast number of parameters and functions

can be recalled and automated. Individual control elements (faders,

rotary dials, keys etc.) can be assigned to CC messages on your

B-CONTROL. Because not only keys but also faders and rotary

dials can be used, control values can be controlled in real time

either statically or dynamically. A list with the standard controller

numbers can be found in this user manuals appendix.
NRPN:

Additionally, controllers that have no standardized assignment

can also be used, and can therefore be assigned according to no

predetermined rule. These controllers are called NRPNs (Non-

Registered Parameter Numbers). NRPNs are further subdivided

into MSB (Most Significant Byte) and LSB (Least Significant Byte)

in order to achieve a higher resolution. A lower resolution is

particularly easy to observe during fader movement of a mixer, in

which 7-bit (= 128 values

) jumps in the signal level

can be heard.

By subdividing NRPNs into MSB and LSB, you can achieve

14-bit resolution of faders and rotary dials, which means that the

movement of a fader is divided into more than 16,000 steps (2

In addition to NRPNs, there are also RPNs (Registered Parameter

Numbers). RPN commands are defined as GM (general MIDI),

GS (Roland) and XG (Yamaha) MIDI standards.
Pitch Bend

The pitch-bend wheel of a keyboard is used for tone modulation

and has its own commands in the MIDI format.
After Touch

MIDI keyboards featuring After Touch can respond to varying

key pressure even after you release the key (i.e. after the keystroke

is over) and can send this data via MIDI. This function either

reacts key-specific (key pressure) or it reacts to all notes at the

same time (channel pressure).
MIDI Machine Control (MMC):

With MIDI Machine Control, you can assign transport functions

of a sequencer or drum computer (e.g. start, stop, FFW/RWD)

and locator points to individual keys with a permanently adjustable

time position (locate, punch in/out points).
Program Change Messages and MIDI Bank Select:

Program change messages are used to recall programs/presets

in MIDI devices connected to your B-CONTROL. 128 program

numbers can be recalled. For devices with more than 128 presets,

use the bank select function, which lets you select a storage bank

before sending a program change.
Running Status:

Because the MIDI interface is a serial data transmission format

(meaning that its data is transmitted as a succession of individual

data segments), it became apparent very quickly that it may not

be fast enough. To avoid perceptible delays in the output of MIDI

data, Running Status was designed. It suppresses the

transmission of the status byte when the same MIDI messages

are transmitted in succession. This means that, for example,

during a continuous change of the data byte of a controller (e.g.

volume), the status byte is only sent once. The only thing that is

transmitted are the changes in the data byte. This goes on until

another status byte is sent. 8 bits are saved for each message

sent.
SysEx Dump:

System-Exclusive

data refer to a function that makes

transmission of nonspecific data via MIDI possible. This is often

used for reading out memory contents and storing them externally.

The status byte notes the data type (SysEx); the first three data

bytes are a manufacturer ID, so that when you have a large MIDI

network, you can still talk to the correct MIDI device.

To make using several identical B-CONTROLs at the same

time possible, you can assign a device number (device ID) in the

global setup menu to each B-CONTROL, which assures that only

the correct device receives the data intended for it.

3. CONTROL ELEMENTS AND

CONNECTIONS

In this chapter, we will describe various control elements of

your B-CONTROL. All controls and connectors are explained in

detail, and well give you useful tips on how to use them.

The 8 infinitely variable push encoders are used to send

MIDI data. They have two functions (turn and press) that

can be assigned to different MIDI commands.
Each of these 16 keys can send one MIDI command.
The four-digit LED display indicates the current operating

software version briefly during startup. After that, it shows

the selected preset number. When in play mode, activating

one of the control elements indicates value changes on the

LED in real time. When in programming mode, it indicates

the type of MIDI commands, program/channel numbers and

parameter values.
Using the ENCODER GROUP keys, four so-called encoder

groups per preset can be recalled, so that eight PUSH

encoders for a total of 64 different MIDI functions are at

your disposal.
These LEDs indicate the following:
MIDI IN, OUT A and OUT B illuminate if MIDI data flows

through the respective connectors.
USB Mode illuminates if a USB connection to a computer is

active (your computer must be on).
The FOOT SW LEDs illuminate if the footswitch is pressed.
FOOT CTRL LED (BCF2000 only) illuminates when the

footcontroller is actuated (MIDI data is sent).
Permanently fixed functions are assigned to this key section:
STORE saves presets.
LEARN gets you to the LEARN mode.
EDIT gets you to the EDIT mode.
Using the EXIT key, you exit a programming level (edit mode/

global setup). Use it also to cancel a store or copy procedure.
The eight 100-mm faders of the BCF2000 are freely

assignable for controlling MIDI commands. They are

motorized, so they automatically slide into the predetermined

position when you switch to another preset. If the software

you are controlling or the MIDI device to which your

B-CONTROL is connected support parameter feedback, the

fader positions change automatically.
Using the PRESET keys, 32 presets can be recalled. The

preset number is shown in the display.
These four keys can be assigned to any MIDI command of

your choice.
The 24 infinitely variable rotary controls (encoders) of the

BCR2000 can be programmed to send MIDI control

commands. The LED circle show the current value.
These are the SWITCH connectors for connecting a

footswitch. Its polarity is automatically detected. On the

BCR2000, the first connector (SWITCH 1) can also be used

to connect a double footswitch with stereo jacks. In this

case, SWITCH 2 must remain unused.
