Use this socket to supply the UMX25 with current from an
external power supply unit (not included).
The USB connector of the UMX25. The connector (type B)
on the device is connected using the cable supplied to a
free slot on the host computer (where you will find a type A
connector). It is compatible with the USB 1.1 and
USB 2.0 standards.
In addition to the connection to the computer, you can use
the MIDI OUT to connect additional MIDI devices, so that
the UMX25 transforms into a fully-featured, easily
accessible MIDI interface for your host computer.
Use the FOOT SWITCH connector to connect a sustain
pedal. This interface is factory preset and assigned to the
MIDI parameter “Foot Pedal” (CC 64), which represents a
switch controller. When the pedal is pressed (and held) in
normal Play mode, it generates a controller with the value
127. When the pedal is released, the controller falls back

to 0 (typical piano sustain pedal behavior). Apart from that
the pedal assignment is the same as the button
assignment, i.e. you can assign any MIDI controller to it.
The POWER switch is used to switch the unit on and off.
Please close all programs if you want to switch off the
UMX25 while the computer is running or terminate the
USB connection.
4. OPERATION
This chapter gives you a detailed description of how to operate
the UMX25. Please note: There is an explicit difference between
buttons (see control elements, ) and keys (control element,
)! Do not mix them up!
4.1 PLAY MODE
After power-up the UMX25 enters Play mode. You can start
playing, modify filter sweeps with the rotary controls, determine
program changes intuitively, realize panorama changes, control
soft synths, and so on…
4.1.1 The FACTORY MEMORY
The FACTORY MEMORY is the internal memory storing the basic
settings of the UMX25. The most important feature of the
FACTORY MEMORY is the controller map described in point .
These settings define a number of useful parameters and are
automatically loaded when the device is switched on.
Assignments that are modified during a session, will be discarded
when the unit is switched off. In order to save the modified
assignments, the UMX25 has been provided with a USER
MEMORY.
4.1.2 The USER MEMORY
Settings that are stored in the USER MEMORY, are stored
permanently in the internal flash ROM and will be retained even
after switching the unit off.
Change to the USER MEMORY by pressing button 6. When you
access the USER MEMORY for the first time, it stores a copy of
the FACTORY MEMORY settings. As soon as you make changes
to the existing controller map, they are stored automatically without
your intervention.
