U-CONTROL UMX25
4. OPERATION
4.2.5 The SNAPSHOT SEND command
The SNAPSHOT command 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.
3) Release the ASSIGN button. The device automatically enters
Play mode again.
The SNAPSHOT command is sent immediately after
playing the keyboard.
4.2.6 LOCAL OFF
The effect of LOCAL OFF is that any data entries made with
the control elements will NOT be passed on to the MIDI OUT
connector or the USB OUT. In LOCAL OFF mode you can, for
example, re-adjust the rotary controls without sending any
information to the external devices connected—which would
normally be the case.
1) Press the ASSIGN button and keep it pressed.
2) Press the button.
3) Release the ASSIGN button and adjust the control elements
as required.
4) Finalize your selection with , or ASSIGN.
In either case the ASSIGN LED goes out and the UMX25
enters Play mode again.
4.2.7 Control elements assignment
In Chapter 4.2.2 we described how to assign an individual
channel to each control element. Here you will learn how to
assign new controllers.
This procedure applies to the MODULATION wheel, the DATA/
VOLUME fader, the rotary controls R1 – R8, the buttons B1 – B8
and to the optional sustain pedal connected to jack .
1) Press the ASSIGN button and keep it pressed.
2) Move or press the corresponding controller or button
respectively, or hold down the sustain pedal.
3) Release the ASSIGN button.
4) Press the number keys on the keyboard to enter the controller
number of your choice. Only values between 0 and 127 can
be entered. Higher values are ignored by the device.
Examples:
- To enter CC 14 press keys and .
- If you want to select CC 107, press , and
.
5) Press to confirm. To discard your assignments either
press the button or the ASSIGN button again. In
either case the ASSIGN LED goes out.
Please note two special cases with regard to a button or the
sustain pedal:
If you assign CC 07 (Channel Volume) to a button,
the channel volume “0” is sent each time you press
the button. This will always mute the channel,
which is a very interesting feature when playing
live.
If you use the controller CC 10 (Panorama) for the
buttons or sustain pedal, pressing the control element
will send out a value of 64. As a consequence, the
channel will always be set to center position in
the stereo panorama.
4.2.8 Program and bank change
The UMX25 provides three options to change programs on
external devices. This is a very powerful function which allows
you to fully exploit the multitude of functions of your sound
modules.
Options a) and b) allow you to select any programs using a
defined selection procedure. Option c) speeds up the procedure,
so that you can select programs at the touch of a button.
a) If you are sure to select only one of 128 different
programs, you can effect program changes in ASSIGN
mode as shown below. However, if the number of 128 is
exceeded, you will have to use the procedure described
in section b).
1) Press the button and keep it pressed.
2) Press the SINGLE key.
3) Release the ASSIGN button.
4) Now define the SINGLE CHANNEL by entering a number
from 1 to 16 using the number keys. In order to assign the
GLOBAL CHANNEL, please press the instead.
5) Press the button.
6) Press the number keys on the keyboard to enter the program
number of your choice. Only values between 0 and 127 can
be entered. Higher values are ignored by the device.
Examples:
- To enter program 15, press keys and
- If you want to select program 127, press ,
and .
7) Confirm your selection with . If you do not like the
selected program, discard your selection with or
press the ASSIGN button again. In either case, the ASSIGN
LED goes out.
b) If you want to make a selection from more than 128
programs, please use the following program change
procedure. In this case your programs will be organized in
banks, which can be selected with a special MIDI instruction
called BANK SELECT. Here’s how it works:
The BANK SELECT instruction consists of two parts: one MSB
part and one LSB part.
The MSB part describes a value range comprising 128 different
values. On many devices this is the more important part of the
BANK SELECT instruction.
The LSB part describes each of the 128 MSBs using 128
additional single steps. In both cases the numbering is from 0 to
127.
In total, the BANK SELECT instruction offers the enormous
value range of 128 x 128 = 16,384 different values. In theory,
this means that you could use external devices with as many
