8U-CONTROL UMX250 User Manual

5)Press the ENTER button on the keyboard to confirm your assignments.

To discard your assignments either press the CANCEL button or the ASSIGN button again. In either case, the ASSIGN LED goes out and the UMX250 quits ASSIGN mode.

(6)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.

(7)The two OCTAVE SHIFT buttons are preset to shift the keyboard range by several 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.

(8)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 (10). All rotary controllers can be assigned to any controller in ASSIGN mode.

(9)The eight buttons B1 – B8 generate switch controllers. Again, these are factory-set functions (see table (10) on the device). Like the rotary controls the buttons can be freely assigned to any controller in ASSIGN mode.

(10)The table shows the controller assignment preset at the factory.

(11)Keyboard legend: Informs you about the special functions performed by individual keys on the keyboard. The individual elements of the keyboard legend are described in detail in Chapter 4 “Operation”.

(12)Use this socket to supply the UMX250 with current from an external power supply unit (not included).

(13)The USB connector of the UMX250. 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.

(14)In addition to the connection to the computer, you can use the MIDI OUT to connect additional MIDI devices, so that the UMX250 transforms into a fully-featured, easily accessible MIDI interface for your host computer.

(15)Use the FOOT SWITCH connector to connect a sustain pedal. This port is factory-set 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.

(16)The POWER switch is used to switch the unit on and off.

◊Please close all programs if you want to switch off the UMX250 while the computer is running or terminate the USB connection.

4. Operation

In the following, we will explain the operation of the UMX250 in detail. Please note the differentiation between buttons (see control elements (9)) and keys (control element (1))! Please do not confuse these!

4.1 Play mode

After power-up the UMX250 is in PLAY mode. You can start playing, modify filter sweeps with the rotary controls, determine program changes intuitively, realize panorama changes, controlsoft synths, and so on.

4.1.1 The factory memory

The FACTORY MEMORY is the internal memory storing the basic settings of the UMX250. The most important feature of the FACTORY MEMORY is the controller map described in point (10). 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 UMX250 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.

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
