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.

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.

Control Elements and
Connections
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).
