User manual M-AUDIO RADIUM49

[. . . ] . 27 Introduction Congratulations on your purchase of the Radium, part of the USB Keystation series of MIDI controllers brought to you by M-Audio. You may use your Radium in conjunction with a USB equipped PC or Macintosh computer and appropriate music software to enter a full range of MIDI note and controller information. You will be able to discover the wonderful world of Computer Music with a set of complete musical instruments from your sound card, sound modules, or workstation. The Radium gives you full control over MIDI parameters, while utilizing proven M-Audio USB MIDI interface technology. The Radium will also serve your needs as a standalone MIDI controller. [. . . ] Your Radium is ready for use. You can run the OMS `Test Studio' utility by going to the `Studio' menu and releasing the mouse on "Test Studio. " Playing a note on your keyboard will give you an audio message from your computer, "MIDI received, " while the arrow pointing to the keyboard icon flashes. Clicking on the keyboard icon with the mouse pointer will send a tone cluster to the Radium output port. The sound module connected to the Radium MIDI Out port should play the chord. Generally, this means selecting "OMS Compatibility, " or "Open Music System" for your MIDI system setup. Setting Up Your MIDI Studio A typical MIDI system set-up would include your Radium, a computer, MIDI sequencing software and/or a MIDI compatible sound module. The Radium is connected to the computer via the USB port connectors, using the supplied USB standard cable. The Radium 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 the section "Using the Radium 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. 12 3. The MIDI Output of the Radium 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 setup pictured below, the Radium 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 Radium 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 Radium. With the power switch set to "USB Power, " the Radium receives power from the USB port on your computer. It is recommended that you plug directly into the USB port on the computer. You may also choose to use power from batteries (Radium49 only) or an external power supply. Additionally, the Radium may be used as a "standalone" keyboard controller, independent of the computer and its USB port. In this case, the Radium must receive power from a power supply, 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. 13 Using the Radium with Your Application Software Once the Radium driver has been installed, you will need to configure your MIDI application software to utilize the Radium. The manner in which this is done varies between applications, so we can just cover the basics here. Generally with both the Mac and PC, most MIDI applications have a MIDI port configuration or settings dialog box, sometimes called "MIDI Devices" or "MIDI Setup. " It is within this dialog box that you will select or enable your MIDI input and output devices. If the Radium drivers are properly installed, then the port selection in this case will be the KEYSTATION SERIES (or "Port 1" on the Mac) in the input column, and then KEYSTATION SERIES (or Port 1) in the output column. You must choose the second selection for each time it is listed in order for OMS to properly process the flow of MIDI information to and from the computer. The output port that you select on a specific MIDI track within your sequence will output MIDI information to the keyboard or sound module that is attached to that port. MIDI Functions MIDI is the acronym for Musical Instrument Digital Interface, which makes all digital musical instruments equipped with this standardized interface able to exchange their MIDI data or "talk to each other. " To explain how MIDI works on your instrument in more detail, the following descriptions outline the MIDI functions of the Radium, which allow you to connect the keyboard to other MIDI instruments and to your computer. [. . . ] These other manufacturer's trademarks are used here for the sole purpose of describing the useful applications of the Radium keyboards which are catered to these products. 21 Rear Panel Features 1. Sustain Jack - This jack allows you to connect an optional footswitch to the keyboard. When the footswitch is depressed, notes played on the keyboard will continuously sound as long as the footswitch is held, while MIDI controller information is sent from the Radium. MIDI "Keyboard" Out Jack - This standard MIDI jack is a direct MIDI out from the keyboard in "standalone" mode, and is used to send MIDI messages to another MIDI instrument (such as sound module).
