What settings do I have to make? Where? How?
Basically, which control element generates which controller must be set on the UMX25, and how incoming controller commands should be interpreted must be set on the receiving device.
Regarding controller assignment, there are two possible principles:
You use the preset controller configuration set in the
factory (see Fig. 3.1, 
). In this case, you only need to make the assignments on the receiving device.
You use your own controller configuration set up in ASSIGN mode. How to assign controllers to the UMX25 is described in Chapter 4 “OPERATION”.
2.2 USB mode and stand-alone operation
The UMX25 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 UMX25 is linked via USB to a computer, the signal flow is as shown below (Fig. 2.1).

After the UMX25 has been connected to the host computer, a virtual MIDI IN and MIDI OUT interface is emulated.
MIDI data generated in the UMX25 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 
). 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 UMX25.
2.2.2 Stand-alone operation
When the UMX25 is not linked via USB to a computer, it is automatically set to
3.CONTROL ELEMENTS AND CONNECTIONS
The following factory settings refer to GLOBAL MIDI channel 1.
The keyboard of the UMX25: 25 large,
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 semitones while playing. The specific amount of pitch bending applied to a sound can be set on the device controlled by the UMX25.
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 UMX25 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 
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 UMX25 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 several 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.

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