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 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.

3. CONTROL ELEMENTS AND CONNECTIONS

3. CONTROL ELEMENTS AND
CONNECTIONS
The following factory settings refer to GLOBAL MIDI
channel 1.
The 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
encoder in the context of the assignment procedure.
The 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 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 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 -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
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 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.
