M-AUDIO OXYGEN OXY8_050503 - Manual (Page 13)

1. The Oxygen 8 is connected to the computer via the USB port connectors,
using the supplied USB standard cable.
2. The Oxygen 8 can play the synthesizer that is part of an internal sound card,
as well as any software synthesizers that are installed in your system.This will
depend on how you set up your software (see section “Using the Oxygen 8
in your Application Software.”) The audio output of the sound card can be
plugged directly into a sound system, or into a mixer, which is then
connected to a sound system.
3. The MIDI Output of the Oxygen 8 is connected to the MIDI In of a sound
module. The audio output of the sound module can be plugged directly into
a sound system, or into a mixer, which is then connected to a sound system.
In the following set-up, the Oxygen 8 is being used as a MIDI controller as well
as a MIDI interface, inputting MIDI data to the computer and its application
software, and outputting MIDI to a sound module from which sounds will be
produced. The Oxygen 8 as a controller may also send MIDI information to an
existing internal soundcard’s MIDI synthesizer or any installed software
synthesizer, outputting the audio from the computer soundcard.
In this scenario, it may not be necessary to apply external power to the Oxygen
8.With the power switch set to “Power Off,” the Oxygen 8 receives power from
the USB port on your computer. It is recommended that you either plug directly
into the USB port on the computer, or use a powered USB hub. You may also
choose to use power from batteries or an external power supply.
Additionally, the Oxygen 8 may be used as a “standalone” keyboard controller,
independent of the computer and its USB port. In this case, the Oxygen 8 must
receive power from either a power supply or batteries, by switching the power
setting on from the rear panel.Also, you will want to use the MIDI out port that
is labeled “Keyboard.” A setup such as this may be used in a performance
situation, or when you wish to use the keyboard without the computer.
