13B-CONTROL DEEJAY BCD3000 User Manual

5.4Signal routing

With the USB interface, you can record and play back up to four audio signals simultaneously. The signal routing is specified by the settings of the applied software (for example, TRAKTOR 3 LE), Control Panel and the state of the buttons on the device.

In Windows, the possibilities of signal routing depend on the chosen driver (ASIO or WDM/MME).

5.4.1Routing possibilities with the ASIO driver (Windows)

STANDARD Mode:

If “STANDARD” is selected in the GLOBAL MODE of Control Panel, only the input signals can be selected. The output assignment is preconfigured. The software outputs 1-2 are routed to the MASTER OUTPUT [39] (rear panel) and the software outputs 3-4 are routed to the PHONES output [14] (front panel). Usually, it is recommended to use the STANDARD mode, which is also the case when using the TRAKTOR 3 LE software.

Advanced Mode:

In Advanced mode, all parameters of the ASIO driver can be adjusted. In Control Panel, you can select the input source for channel IN A (CH 1-2, Mic or Phono A). The input source for IN B (CH 3-4, Phono or Line) is selected with the PHONO/LINE switch [38] on the rear panel of the BCD3000. The playback channels CH 1-2 or CH 3-4 are also selected in Control Panel for the main outputs [39] and the headphone output [14] (in the MASTER OUT and PHONES OUT fields). If you assign the software output channels 1-2 to the headphone output, the channels 3-4 are automatically assigned to the MASTER OUTPUT, and vice versa.

5.4.2Routing possibilities with the WDM/MME driver (Windows)

The WDM/MME driver supports playback/recording of 2 audio signals.

For 2-channel recording you can select input IN A or IN B in the WDM/MME window of the control panel. When you choose IN A, you can also determine the signal to be recorded (Phono A or MIC).

When you select IN B, you can use the PHONE/LINE switch to determine the signal to be recorded (phono or line).

Playback with the WDM/MME driver is always in stereo, which is why the MASTER output and the PHONES connector of the BCD3000 provide the same music signal.

5.4.3 Routing possibilities (Mac OS X)

With Mac, the BCD3000 always runs in the “STANDARD” mode, which means that only the input signals can be configured. For channel IN A, you can assign Mic or Phono A with MIDI commands in an appropriate software (see Table 6.7). The input source for IN B (CH 3-4, Phono or Line) is selected with the PHONO/LINE switch [38] on the rear panel of the BCD3000.

The output assignment is preconfigured. The software outputs 1-2 are routed to the MASTER OUTPUT [39] (rear panel) and the software outputs 3-4 are routed to the PHONES output [14] (front panel).

6. MIDI Control

All control functions of the BCD3000 are sent to your computer as MIDI data.

The Musical Instruments Digital Interface is a generic, non-manufacturer-specific standard that enables communication between electronic musical instruments. Although the BCD3000 is not equipped with the “classic” 5-pin MIDI connectors, it still uses the MIDI protocol for data transmission via USB. Thus, the BCD3000 can also control third-party software, as long as it is able to “speak” MIDI. In turn, the BCD3000 can receive MIDI data and use them to show the switching status of the button LEDs.

Primarily, two MIDI data types are used: Control Change (CC no.) and Note commands (Note no.). The CC commands allow values, which change continuously, to be transmitted in real time. Button functions are sent with Note commands. You can match the MIDI commands to the software functions in the DJ software of your choice. Please note that the different behaviors of the LED control and the buttons’ Toggle On/Off mode depend on the selected GLOBAL MODE, as explained in Chapter 4.2 under “The MIDI Tab”.

6.1 Sending control change functions

All rotary knobs, faders, wheels and the crossfader are control elements that send CC data. A CC number is assigned to each control element; the transmitted absolute values range between 0 and 127. The Scratch wheels are the exception, owing to the fact that continuous encoders do not transmit absolute values. They send value changes (increment = +1, decrement = -1) when used.

The following table shows the regular assignment of CC numbers categorized in function groups.
