U-CONTROL UMX25
4. OPERATION
The following control element assignments including channel
information can be permanently stored in the USER MEMORY:
- FOOT SWITCH connector
- OCTAVE SHIFT button
- VOLUME/DATA fader
- PITCH BEND wheel
- MODULATION wheel
- Rotary controls R1 - R8
- Buttons B1 - B8
4.2 ASSIGN MODE
As already mentioned in the preceding chapters, the ASSIGN
mode is a powerful tool which allows you to re-configure the
UMX25 to an extremely easy-to-use controller.
The fundamental logic of the assignment procedure was already
presented in chapter “3. CONTROL ELEMENTS AND
CONNECTIONS”.
4.2.1 GLOBAL CHANNEL adjustment
MIDI channels are classified into two types: one GLOBAL
CHANNEL and 15 additional SINGLE CHANNELS.
The GLOBAL MIDI CHANNEL is a factory setting and all MIDI
instructions are sent over this channel: messages of various
control elements as well as note-on and note-off messages.
Please proceed as follows to modify the GLOBAL MIDI CHANNEL:
1) Press the ASSIGN button and keep it pressed.
2) Press the button.
3) Release the ASSIGN button.
4) Now define the GLOBAL CHANNEL by entering a number
between 1 and 16 using the number keys. If you enter a
number greater than 16, your entry will be rejected.
Examples:
- If you want to enter channel 14, press keys
and
.
- To enter channel 7 press key .
5) In order to confirm your selection, press the key.
To discard your assignments either press the
button or the ASSIGN button again. In either case the
ASSIGN LED goes out.

Ex works the GLOBAL CHANNEL is set to channel 1.
4.2.2 Individual channel assignment
The assignment of individual control elements to a certain channel
is useful if you want to control external devices independently of
one another.
Example:
You play synthesizer A over channel 2 from the keyboard, while
synthesizer B is controlled on channel 5 by a sequencer software.
Now you can control the filter frequency of device B in real time
using one of the eight rotary controls, and at the same time
continue playing device A without changes to the filter frequency.
1) Press the ASSIGN button and keep it pressed.
2) Operate the control element whose channel shall be set to
differ from the GLOBAL CHANNEL. If it is a controller or a
fader, move it briefly. If it is a button, press it once. Now the
UMX25 “knows” which control element shall be assigned to
a SINGLE CHANNEL.
3) Release the ASSIGN button.
4) Press the button.
5) Now define the SINGLE CHANNEL by entering a number
between 1 and 16 using the number keys. If you enter a
number greater than 16, your entry will be rejected.
Example:
- If you want to enter channel 11, press keys
and
.
- To enter channel 4 press key .

Special case: If you want to assign the control element
to the GLOBAL CHANNEL again, please press the 0
key next to the ENTER key (instead of the number keys
1 to 9).
6) To finalize your settings, press the ENTER button. To discard
your assignments either press the CANCEL button or the
ASSIGN button again. In either case the ASSIGN LED goes
out.

The channel set-up of all control elements of the UMX25
is based on the GLOBAL CHANNEL. This means that a
control element is always set to the GLOBAL CHANNEL
until you assign a different channel to it. Whenever
you change the GLOBAL CHANNEL you also change
the channels assigned to the various control elements!
4.2.3 GLOBAL CHANNEL assignment:
In comparison to the procedure described in the previous chapter,
the advantage of the method shown here is that you have to
press fewer buttons to make adjustments.
1) Press the ASSIGN button and keep it pressed.
2) Operate the control element whose GLOBAL CHANNEL
shall be set.
3) Release the ASSIGN button.
4) Press the SINGLE-key.
5) Press the 0-key.
6) Press to confirm. Press or the ASSIGN
button again to discard your assignments. In either case
the ASSIGN LED goes out.
4.2.4 The PANIC key combination
Imagine you have already worked several hours on a song and
suddenly one of your sound modules produces a “hanging note”.
If you execute a PANIC instruction, a sound module receiving
this instruction will be muted immediately.
1) Press the ASSIGN button and keep it pressed.
2) Press or .
3) Release the ASSIGN button. The device automatically
enters Play mode again.

The instruction chosen will be sent immediately after
pressing one of the two buttons mentioned above.
4.2.5 The SNAPSHOT instruction
The SNAPSHOT instruction transmits all parameters including
their current values: all control element assignments as well as
the current channel settings are sent out from the MIDI OUT
connector and the USB output of the UMX25.
In this way it is possible to transmit the entire UMX25 mapping to
a sequencer software at the beginning of a song. The song can
then be played back with the final controller values adjusted for it.
If the parameters of an external device have been changed, you
can also use SNAPSHOT to correct the values.
1) Press the ASSIGN button and keep it pressed.
2) Press the button.
