B-CONTROL FADER BCF2000-WH

A note command can only be assigned to keys,

footswitches and push functions of the encoder.

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. An illustration

of the control elements with the corresponding numbering can be

found on the next page.

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 LED illuminates if the footswitch is pressed.
FOOT CTRL LED 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 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.
These are the MIDI connectors of your B-CONTROL.

Depending on the operating mode, MIDI OUT B doubles as

MIDI THRU.
This is the SWITCH connector for connecting a footswitch.

Its polarity is automatically detected.
CONTROLLER connector. Here, you can connect an

expression pedal that can be used for controlling assignable

MIDI data.
