Number Keys: The Radium allows you to use the numeric keys instead of the DATA ENTRY slider to specify the Control Change parameter data.This is done by pressing the MIDI/SELECT button, CC (No. or Data) key, required number key(s), and the Enter key. As an example, to assign a Control Change value of 7, and CC Data value of 123:

1.Press the MIDI/SELECT button.

2.Press the CC No. key.

3.Press the key labeled “7.”

4.Press the Enter key, in order to specify the Control Change as 7.

5.Press the CC Data key.

6.Press the number keys 1, 2 and 3, in order.

7.Press the Enter key, to specify the value 123, then press the MIDI/SELECT button.This completes the process.

PROGRAM Key: By use of the MIDI/SELECT button and PROGRAM key, in combination with the numeric and ENTER keys, you can select any patch number between 1 and 128. This is done using the following sequence. If, for example, you want to change the voice to 67 (General MIDI TenorSax), press the MIDI/SELECT button and then the PROGRAM key. Now press numeric key number 6, then 7. Lastly, press the ENTER key, followed by the MIDI/SELECT button to finish the change.

NOTE: After pressing either the ENTER or CANCEL key, the LED display will show “—”, and will not clear until you press the MIDI/SELECT button to finish your choice.

Presets: The Radium can save fifteen Presets in memory. This allows you to assign 16 controller values to the sliders and knobs in one preset, then assign 16 different values to those same sliders and knobs, without losing the initial settings. To change to another Preset, press the MIDI/SELECT button and then the UP/DOWN buttons to choose one of the fifteen Presets. The display will read “P1” through “P15” while you are changing presets.

The chart on the following page lists the factory default Presets, desugned to be useful in a variety of software programs and performance scenarios.
