U-CONTROL UMA25S User Manual
2. USB Mode with MIDI OUT:
Fig. 1.6: USB mode with MIDI OUT
In this mode, the keyboard messages are transmitted via USB to the  computer 
and simultaneously to MIDI OUT. The messages from the computer are only 
picked up by the UMA25S and not passed on to MIDI OUT.
This mode is ideal for recording your keyboard performance to your computer 
even when your sequencer or virtual instrument produces high latencies. To avoid 
this problem, use a rack synthesizer while recording but the virtual instrument 
during playback. The MIDI messages are sent to the computer and, at the same 
time, to the MIDI output.
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.  Press ENTER to confirm or EDIT/EXIT to cancel.
The selected USB mode is now active and the keyboard automatically switches 
back to Play Mode.
2.  Software Installation
2.1  Driver installation
With Windows XP/Vista and Mac OS X operating systems, the UMA25S is detected 
as soon as you connect a USB cable to your computer. After detection, you can 
kick off right away. Thanks to the implementation of Core Audio in Mac OS X, it is 
possible to process your audio with extremely low latency.
2.1.1  Windows XP MIDI driver
Optionally
, you can install the BEHRINGER MIDI driver found on the supplied 
CD. The advantage of this driver is its multi-client support, which lets you 
simultaneously use several MIDI programs together with the UMA25S. 
Another advantage is that the model name is displayed in the selection dialog 
box of the MIDI driver.
Information on installing the driver is found on the CD in the ReadMe file of the 
according folder.

2.1.2  Windows XP/Vista audio driver
Optionally
, you can also install the BEHRINGER USB ASIO driver, which is 
included on the CD as well. Use this driver in case you want to work with the least 
possible latency of audio signals. Most professional music applications, such as 
Ableton Live and Compact, use ASIO drivers.
Information on installing the driver is found on the CD in the ReadMe file of the 
according folder.
