USB mode and stand-alone operation
2.2
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.
USB mode
2.2.1
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
(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 UMX.
Stand-alone operation
2.2.2
When the UMX is not linked via USB to a computer, it is automatically set to
stand-alone mode. In this case, the UMX can only send out MIDI data from its
MIDI OUT connector.
Control Elements and
3.
Connections
The following factory settings refer to GLOBAL MIDI channel 1.
◊
The
[1]
keyboard
of the UMX has 49 or 61 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
[2]
MODULATION
wheel is factory-set to function 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
[3]
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. 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
[4]
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
[5]
ASSIGN
button allows you to assign different functions to the various
control elements.
The basic principle is always the same:
Press the ASSIGN button and
1)
keep
it
pressed
. The status LED above the
button lights up. The UMX signals that it has entered ASSIGN mode.
Select the control element to which you would like to assign a new MIDI
2)
function by operating it.
Release the ASSIGN button.
3)
Depending on the choice you made, you may have to define an additional
4)
value range (see below for more details).
Press the
5)
ENTER
key on the keyboard to confirm your assignments.
To discard your assignments either press the
CANCEL
key or the ASSIGN
button again. In either case, the ASSIGN LED goes out and the UMX quits
ASSIGN mode.
The
[6]
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
[7]
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
[8]
R1 – R8
generate continuous
controller information. They are the controllers that are shown above
the buttons in the table 10. All rotary controllers can be assigned to any
controller in ASSIGN mode.
The eight buttons
[9]
B1 – B8
generate switch controllers. Again, they are
assigned to various default functions (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 factory-set controller assignments.

individual keys on the keyboard. The individual elements of the keyboard
