Behringer U-CONTROL UMX61 Control Elements and Connections, USB mode and stand-alone operation

U-CONTROL UMX49/UMX61

2.2 USB mode and stand-alone operation

The UMX can be operated as a USB interface or stand-alone device. The two modes are different with respect to the MIDI signal flow.

2.2.1 USB mode

When the UMX is linked via USB to a computer, the signal flow is as shown below (fig. 2.1).

After the UMX has been connected to the host computer, a virtual MIDI IN and MIDI OUT interface is emulated.

MIDI data generated in the UMX are first sent over the USB interface to the host computer, where they are received at the emulated MIDI IN. A sequencer software running on the host computer receives the MIDI data via the MIDI IN and relays them to the emulated MIDI OUT – if all sequencer parameters are set properly. The data are then sent back to the UMX via the USB interfaces on the computer/UMX, where they are looped through to the physical MIDI OUT ( ). From here, the MIDI data are sent to the devices connected to the MIDI OUT.

The MIDI OUT connector can also be used as a normal MIDI interface, independently of the sequencer software operating the UMX.

2.2.2 Stand-alone operation

When the UMX25 is not linked via USB to a computer, it is automatically set to stand-alone mode. In this case, the UMX25 can only send out MIDI data from its MIDI OUT connector.

3.CONTROL ELEMENTS AND CONNECTIONS

The following factory settings refer to GLOBAL MIDI channel 1.

The keyboard of the UMX25: 25 large, velocity-sensitive keys for maximum playing comfort. The keyboard not only

provides for playing, but also functions as an encoder in the context of the assignment procedure.

The MODULATION wheel functions ex works as a conventional modulation wheel (MIDI CC 1). In ASSIGN mode, any MIDI controller can be assigned to it. When you release the MODULATION wheel, it retains its adjusted value.

The PITCH BEND wheel is normally used to change the pitch in real time. In this way, a sound can be “bent” upwards/downwards by several half-tones while playing. As a default factory setting, pitch bending is assigned to this wheel. However, in ASSIGN mode you can assign any MIDI control command to the pitch wheel.

Ex works, the VOLUME/DATA fader controls the volume of the notes played on the keyboard (MIDI CC 7). In ASSIGN mode, it can be set to control any MIDI controller.

The ASSIGN button allows you to assign different functions to the various control elements.

The basic principle is always the same:

1)Press the ASSIGN button and keep it pressed. The status LED above the button lights up. The UMX signals that it has entered ASSIGN mode.

2)Select the control element to which you would like to assign a new MIDI function by operating it.

3)Release the ASSIGN button.

4)Depending on the choice you made, you may have to define an additional value range (see below for more details).

5)Press the -Taste. button on the keyboard to confirm your assignments. To discard your assignments

either press the -button or the ASSIGN button again. In either case the ASSIGN LED goes out and the UMX quits ASSIGN mode.

The USER MEMORY button is used to recall the internal memory. The internal memory contains all assignment information set in ASSIGN mode. Any changes that were made after USER MEMORY selection are automatically saved without further user prompts. The USER MEMORY is retained even after the unit is switched off.

The two OCTAVE SHIFT buttons are preset to shift the keyboard range by up to three octaves up or down. The associated LEDs help you identify the current octave setting (see table 3.1). Since the OCTAVE SHIFT buttons can also be assigned to any MIDI controller, we would like to refer you to chapters 4.2.8 and 4.2.9 for detailed information.

The eight high-resolution rotary controls R1 – R8 generate continuous controller information. They are the controllers

that are shown above the buttons in the table . All rotary controllers can be assigned to any controller in ASSIGN mode.

The eight buttons B1 - B8 generate switch controllers. Again, they are assigned to various functions ex factory

(see table on the device). Like the rotary controls the buttons can be freely assigned to any controller in ASSIGN mode.

The table shows the controller assignment preset at the factory.

Keyboard legend: Informs you about the special functions performed by individual keys on the keyboard. The individual elements of the keyboard legend are described in detail in chapter “4. Operation”.
