B-CONTROL FADER BCF2000/B-CONTROL ROTARY BCR2000

Table explanation:

All settings in the EDIT mode are made by turning the first six

push encoders. Pressing the push encoder displays its current

value. In addition, the setting options depend on whether the

selected control element is a SWITCH type or CONTINUOUS

type.

s SWITCH-type control elements are buttons, press functions

for push encoders and footswitches.

s CONTINUOUS-type control elements include the eight

BCF2000 faders, the 24 encoders of the BCR2000, the turn

function of the push encoders and the sustain pedal

(BCF2000 only).

In the EDIT mode, Push Encoder 1 selects (by turning) the

type of command assigned to a control element.

With Push Encoder 2, select a MIDI channel through which

that control elements data is sent.

Push Encoders 3 - 5 set parameters and values for the selected

MIDI type. They vary depending on the MIDI function. More details

about this subject can be found later in this chapter.

Push Encoder 6 (Controller Mode) selects how the previously

selected control element behaves, depending on whether it is a

SWITCH or a CONTINUOUS type.

SWITCH-type control elements have two different modes:

Toggle On and Toggle Off. Toggle On is similar to a switching

function (e.g. a light switch). Each time you press the switch, the

value sent alternates between the on value (set by encoder 4)

and the off value (set by encoder 5). This setting is perfect for

triggering drum loops from a sampler (press once = start, press

again = stop).

The Toggle Off mode corresponds to a momentary-contact

button, comparable to the switch of an electric door opener. The

on value is sent only as long as the button is pressed. After

releasing the button, the off value is sent. Use this control type

to trigger short sound FX or samples (similar to using a keyboard)

by sending Note On and Offs.

CONTINUOUS-type element controls are divided into

Absolute, Absolute (14 bit), Relative 1 (2nd complement),

Relative 2 (binary offset), Relative 3 (MSB, most significant

bit), Relative 1 (14 bit), Relative 2 (14 bit), Relative 3 (14 bit)

and Increment/Decrement. Absolute means absolute data

values although jumps may occur when changing values. With

Relative, the current parameter value is continued independently

from the position of the control. Absolute (14-Bit) or one of the

Relative (14-Bit) modes are standard modes for value changes

at NRPNs with high resolution. This is necessary with some

software mixers if more than 128 steps are needed. Increment/

Decrement serves as a step-by-step increase or decrease of

values by using the Data Increment/Decrement commands

(see list 5.1 in the appendix).

+ The classic controler mode for most applications is

absolute. All other modes have to be supported by

the MIDI software or the device to be controlled.

Program Change:

With the encoders 3 and 4 you can select bank numbers. If a

MIDI device contains more than 128 presets/programs, first a

bank change command has to be sent. Even though this is a

controller command, it has to be sent before the program change

(and is therefore adjustable) since it is linked to the preset change.

If the bank select message is not needed, simply select off.

Encoder 5 selects the program number. If the selected

control element is a control dial (continuous type), the

program number is directly selected when turning the dial.

Pressing the switch directly selects the assigned program

number. This can be useful if you always want to start from

the same preset.

Control Change CC:

A control change consists of a controller number and its

respective value. Encoder 3 sets the controller number. With

buttons, different values can be sent when pressing and releasing

(to be set with encoders 4 and 5). This function is useful if fixed

parameter settings are to be sent.

With faders and control dials (continuous type), the value range

can be determined by using encoders 4 (minimum value) and 5

(maximum value).

+ Alternatively, you can invert the value scale by assigning

127 as the minimum value and 0 as maximum value

(scale inversion). A classic application is the draw bar

control of virtual or digital organs or organ expanders.

If assigning controller 7 (volume) to the faders of the

BCF2000 this way, the signal becomes quieter when

moving up the fader. Moving down the fader is similar

to moving out the draw bars, and the volume increases.

NRPN:

A NRPN is needed if none of the 127 standardized controller

numbers are available for a certain function.

Encoder 3 selects the parameter number. For assigning mixer

faders, we recommend the high resolution (Absolute 14 bit),

provided that the control hardware/software supports it.

Note:

Of course, a note can only be assigned to one SWITCH element.

The note is set with encoder 3. Note C3 (C key) corresponds with

note number 60. Encoder 4 sets the note velocity (note volume).

Pitch Bend:

Pitch bend is assignable to only one CONTINUOUS element.

Since this is a type of command with its own status byte, selecting

a MIDI channel (Encoder 2) and Range (Encoder 4) is sufficient.

After Touch:

Normally, ALL is selected here. This means that After Touch

affects all notes equally (Channel Pressure). If you want to use

a polyphonic After Touch (Key Pressure), the single note on

which After Touch should have an effect can be selected using

encoder 3. Since this process is only supported by a few tone

generators, channel After Touch will be best most of the time.

When a switch element has been selected, an on and off value

can also be set (release dynamic). Therefore, you can limit the

modulation range (FX depth) using After Touch.

MMC:

MIDI Machine Control data is only assignable to button

elements.

Encoder 4 (Value 1) sets Locate Time hour and minute values,

while encoder 5 (Value 2) sets seconds and frames. The Locate

Position is always sent before the MMC command. We therefore

have the following logic-switching sequence:

If the Locate parameter has been selected, the sequencer or

hard drive recorder always jumps to the set position. If Play has

been selected as the parameter (for a button), the sequencer

always starts from the set locator point as soon as the button is

pressed. Rewind always begins at the chosen locator point.

Select the frame rate with encoder 6: 24, 25, 30 (non-drop), 30d

(drop frame) or off (in this case only the MMC message is sent,

without any information of the locate position).
