An Overview

The Radium is a fully functional MIDI controller. Its touch-sensitive keys can be
set to play any octave or transposed pitch, while the Radium’s pitch wheel, mod
wheel and data slider with the addition of sixteen programmable rotary knobs
and sliders make it the most versatile MIDI controller of its class. Its compact
size and powerful controller features make it the ultimate in portable keyboard
controllers.Virtually any type of MIDI controller information can be sent from
the Radium to your computer, using the power and convenience of the Mac or
PC computer’s USB port.Additionally, the Radium can operate as a “standalone”
MIDI controller, independent of the computer.The rear panel MIDI port marked
“keyboard” is used for this purpose.

Contained within the Radium is a USB MIDI interface. Simply plug the Radium
into your computer’s USB port, install the included drivers and enable the MIDI
interface within your music software. This combination of a versatile keyboard
controller and a USB MIDI interface allows you record and control MIDI
information within your music application, plus adds a MIDI output port to
which you can connect a MIDI sound module or drum machine.The rear panel
MIDI port marked “USB” is used for this purpose.

The Radium may be powered by one of two sources: an external power supply
or “parasitically” from the voltage it receives from the USB port. For the most
consistent performance, we recommend using a power supply, even when using
the Radium with your computer’s USB port.To power from the USB port only,
plug the Radium directly into the computer’s USB port, not a powered USB hub.
When using the Radium in standalone mode, a power supply must be used.
When using an external power supply (optional), it is important to use only a
supply with the proper 9vDC, 500ma rating. This may be purchased locally or
through M-Audio.

On a PC:

You must be running Windows 98 or higher to properly use the

Radium. Windows NT is not supported. Also, your motherboard must support
USB 1.1. It is possible for a motherboard to support USB and yet not have the
physical port connectors installed. A simple USB back panel extender can be
purchased at a computer supply store and can be installed easily to provide USB
port connectors.

On an Apple Computer:

Your Mac must support USB with the built-in ports.

The USB ports on the iMac or PowerMac G3/G4 will work just fine. A Mac OS
that supports USB will also be required.We recommend MacOS 9.2.2 or higher.
We cannot guarantee performance of device when using non-Apple USB ports.

IMPORTANT: For MacOS 9, an OMS MIDI driver is provided. You MUST have
a sequencer program that supports OMS, and have OMS properly installed
in order to use the Radium.
