U-CONTROL UMA25S User Manual 1. Introduction Thank you for showing your confidence in us by purchasing the UMA25S. The UMA25S is an extremely flexible master keyboard with a control section that can be used for a wide array of applications.
U-CONTROL UMA25S User Manual External power supply: 1.3 Hardware configuration If you neither want to draw the power supply via USB nor power the device with batteries, there is yet another possibility to connect the UMA25S to an external power supply unit. Please observe the correct operational data (DC 9 V; 200 mA) and correct polarity of the connector. Further information can be found above the DC input on the rear panel of the device. Reverse polarity may cause damage to the electronics.
U-CONTROL UMA25S User Manual 1.3.1 Stand-alone mode 1.3.2 USB mode (Default) In case the USB connection is not available or detected, the UMA25S automatically switches to the stand-alone mode. In this mode, you can use the UMA25S to control external units via the MIDI output. This is the default setting when the device is turned on. If the UMA25S is connected to a computer via USB, the keyboard automatically switches to this mode.
U-CONTROL UMA25S User Manual 2. USB Mode with MIDI OUT: Selecting the USB mode: 1. Press the EDIT/EXIT push button. 2. Press the key on the keyboard labeled MIDI OUT or MIDI THRU. 3.

U-CONTROL UMA25S User Manual 5. UMA25S as USB/MIDI Controller At the highest control level of the U-CONTROL, you play and control the MIDI data (Play Mode). The UMA25S has an array of control elements with which you can control your MIDI equipment via the MIDI output (22) or with which you are able to control your computer applications via USB (using the MIDI standard). Most Digital Audio Workstations (DAWs) are capable of receiving control data according to MIDI specifications.
U-CONTROL UMA25S User Manual What can I control with the UMA25S? 5.2.1 Changing the velocity curve Basically, you can control any device that is MIDI compatible. Both hardware and software MIDI devices are controlled in exactly the same way. The only difference between them is the wiring. You can adjust the UMA25S’ sensitivity which has an effect on the velocity with which the keys are pressed and therefore also on the volume level.
U-CONTROL UMA25S User Manual Transpose function: 5.2.4 The panic function Use the OCTAVE push buttons to transpose upward or downward in semitone steps. The Panic function is provided to silence stuck MIDI notes. A MIDI note can get stuck when the connection between the sending and the receiving device is interrupted for some reason or other and the required Note Off message cannot be received. This is perceived as a stuck note that doesn’t fade out.
U-CONTROL UMA25S User Manual MIDI Data Type: The E9 rotary knob lets you select the message type that is to be assigned to a control element. Refer to Chapter 5.5 for information on MIDI messages. Example of the Learn function: In order to control the main volume level of a virtual instrument with the E19 slider, follow the steps below: MIDI Send Channel: The E10 rotary knob allows you to select the MIDI channel on which the message is supposed to be sent.
U-CONTROL UMA25S User Manual 5.5 MIDI messages 5.5.1 Program change and midi bank select Program Change messages are used to activate the memory banks of the connected devices. 128 program numbers are available to activate presets. For devices with more than 128 presets, there is the Bank Select function which allows you to select a memory bank before sending a Program Change. The Bank Select message consists of two parts: an MSB (Most Significant Bit) part and an LSB (Least Significant Bit) part.
U-CONTROL UMA25S User Manual 5.5.2 Control changes 5.5.3 NRPN The Control Change messages (CC) belong to the most “powerful” MIDI messages. They allow you to control plenty of parameters and functions. You can assign CC messages to each control element on the UMA25S. Since it is possible to use push buttons, sliders and rotary knobs, the controller values can be controlled either statically or dynamically in real time. A list of the assigned standard controller numbers are found in Table A.
U-CONTROL UMA25S User Manual 5.5.5 Pitch bend 5.5.9 Using keys as control elements The Pitch Bend wheel E17 on the UMA25S is used to change the pitch of a note. It has its own type of message in the MIDI specification. Not only the switch elements but also the keys on the keyboard can trigger CC messages and Note messages. The advantage is that you don’t have to do without the familiar feel of keys and velocity sensitivity.
U-CONTROL UMA25S User Manual 5.6 More functions in edit mode Swap function: All of the functions mentioned in this chapter are available in Edit Mode. Press the EDIT/EXIT push button to switch to Edit Mode. 5.6.1 Show element function The Swap function allows you to switch the MIDI channel assignment of an array grouped in eight: swap the assignment of channels 9–16 when channels 1–8 were selected beforehand.
U-CONTROL UMA25S User Manual Assigning the superior GLOBAL SEND CHANNEL: 5.6.6 Action send function 1. Press the EDIT/EXIT push button for a short time. The device switches to Edit Mode. “Edt” appears on the display. The Action Send function lets you trigger the transmission of a specific control element. For example, this function allows you to send a one-off MIDI message which is only supposed to be assigned to a control element for a short time. 2.
U-CONTROL UMA25S User Manual SysEx Dump ALL: By turning the E11 rotary knob, the entire memory contents of the 16 presets is sent as SysEx dump via MIDI. During the dump, the display flashes “Run”. You can cancel the process by turning the E11 rotary knob until “End” appears on the display. In order to receive a SysEx dump, no settings on your equipment have to be adjusted.
