(22)MIDI OUT allows the UMA25S to connect to a computer. On the other hand, it provides a connection to additional MIDI devices, making the UMA25S
a
(23)The EXPRESSION connector lets you hook up a foot pedal which can be used to control assignable MIDI data. The foot pedal typically controls the volume level, which is then referred to as expression pedal, but can also be used to control a filter’s cutoff frequency or even a typical wah effect.
(24)The SUSTAIN connector allows you to connect a Sustain pedal.
This connector is assigned by default to the MIDI parameter “Damper Pedal” (Sustain, CC 64), which represents a switch controller. When the pedal is pressed (and held) while in normal Play Mode, it generates a controller with the value 127. As soon as the pedal is released, the controller jumps to the value 0 (which is the typical behavior of a piano’s sustain pedal). Aside from this, you can assign the pedal connector to any MIDI controller as is the case with the push buttons.
(25)This is the USB connector on the UMA25S. The connector (type B) on the device is connected to a free port (type A) on the host computer using the supplied cable. It is compatible with both USB 1.1 and USB 2.0 standards.
(26)Use the DC IN connector to supply the UMA25S with power from an external power adapter (not included).
(27)The POWER switch is used to turn the UMA25S on and off. Be sure the POWER switch is turned to the “Off” position when connecting to the mains.
◊Please close all software applications before turning off the UMA25S or disconnecting the USB cable while the computer is on.

Fig. 4.1: Using the audio connectors
The UMA25S provides a professional recording interface between mixer and computer when used alongside a suitable mixer. This type of setup allows you to record several signals onto the computer and to play several recorded takes or playbacks simultaneously. Additionally, it lets you listen to the entire recording on loudspeakers (or headphones). Figure 4.1 shows a possible setup with
the UMA25S.
Connect the subgroup outputs with the inputs of the UMA25S. It is possible to connect either the TAPE INPUT connectors or your monitor speakers to the outputs of the interface. For monitoring purposes, plug the stereo headphones into the PHONES output on the UMA25S or into the headphone output on the mixer. Use the supplied USB cable to connect your computer by way of the USB port.
By routing the channels you want to record to the subgroups, it is now possible to use the mixer’s channels to record one instrument after the other onto your computer. If you connect the outputs of the UMA25S to the free channel inputs (not via TAPE INPUT), make sure that the signal is not switched to the subgroup but to the main output of your mixer to avoid feedback. Be also sure to select the correct monitoring paths in the Control Room section on the mixing console.
If you feed the UMA25S back through a channel input (not TAPE INPUT), you can set up an additional monitor mix for performing musicians by using the Aux Send (for example, Aux 1) of the specific channel. In case the musicians want to hear themselves as well as the playback or previous recording takes, use the Aux Sends in the recording channels to mix the recording signals with the monitor mix.
