6.3 Receiving MIDI commands
The reception of MIDI data also allows for transmitting commands
from third-party DJ software to your BCD3000. Although this
function is not necessary to control the device from the software,
you can still display the switching status of button LEDs, which
enables you to work more intuitively.
All button LEDs receive MIDI control change data (on/off). If the
controller value transmitted is between 0 and 63, this value
corresponds to the switched-off status (LED off). If the value is
64 or higher (max. 127), the LED illuminates.

Data request for all moving elements:
If the “Data Request” command (demand for data) is sent from a
suitable software application to the BCD3000 as “Control Change”
command (100) on MIDI channel 1, the B-CONTROL transmits its
current controls settings to the MIDI or DJ software application.
This affects all knobs and faders apart from both wheels and
buttons.
MIDI channel MIDI CC no.

Selecting the input channel:
You can select the analog input A (see chapter 2.3) via MIDI. To
do this, a program change command must be sent to the
BCD3000.

Acceleration behavior of the Wheels:
Both wheels are automatically selected when the acceleration
option is switched on. The quicker you turn one of the wheels,
the stronger the value changes. In TRAKTOR 3 LE, this means
the following:
V In PLAY mode, you can speed up or slow down the track
quicker.
V In PAUSE mode, you can move quicker through the track.
The value change relates directly to the wheel’s speed when
scrolled manually. When the SCRATCH button is activated, the
acceleration is temporarily turned off in order to ensure an optimum
scratch behavior.
In case you want to deactivate the acceleration when using
other MIDI software applications, apply a MIDI command that is
transmitted from the MIDI application to the BCD3000. After doing
so, the value changes will be constant when scrolling the wheel
(left turn: 63, right turn: 65), regardless how quick.
