U-CONTROL UMX250 User Manual

2.2.1  USB mode
When the UMX250 is linked via USB to a computer, the signalflow is as shown 

below (Fig. 2.1).
After the UMX250 has been connected to the host computer, a virtual MIDI IN 

and MIDI OUT interface is emulated.MIDI data generated in the UMX250 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 

UMX250 via the USB interfaces on the computer/UMX250, where they are looped 

through to the physical MIDI OUT  

(14)

. From here, the MIDI data are sent to the 

devices connected to the MIDI OUT.
The MIDI OUT connector  

(14)

  can also be used as a normal MIDI interface, 

independently of the sequencer software operating the UMX250.

2.2.2  Stand-alone operation
When the UMX250 is not linked via USB to a computer, it is automatically set to 

stand-alone mode. In this case, the UMX250 can only send out MIDI data from its 

MIDI OUT connector.

The following factory settings refer to GLOBAL MIDI channel 1.

(1) 

The KEYBOARD of the UMX250: 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.

(2) 

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.

(3) 

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 UMX250.

(4) 

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.

(5) 

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 UMX250 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).
