6. Instruções de operação
6.1 Notas de execução
Once connected and configured, simply press the keys on the Radium 49 to send MIDI note data to your software instruments. The velocity sensitivity of the keys will translate into dynamic variations in your sound.
6.2 Using Controller Knobs
The 8 assignable controller knobs can be mapped to various parameters within your DAW or software instruments. This allows for real-time control over sound characteristics.
- Atribuição: The method for assigning knobs varies by software. Typically, you will enter a "MIDI Learn" mode in your DAW, select the parameter you wish to control, and then turn the desired knob on the Radium 49.
- Usos comuns: Control volume, pan, filter cutoff, resonance, effect send levels, or any other MIDI-mappable parameter.
6.3 Rodas de Inclinação e Modulação
- Roda Pitch Bend: Move this wheel up or down to temporarily raise or lower the pitch of the notes being played. It typically springs back to the center position.
- Roda de modulação: Move this wheel to add modulation effects, suchs as vibrato, tremolo, or filter sweeps, depending on how your software instrument is configured. This wheel usually stays in its last set position.
6.4 Octave Transposition
Use the dedicated Octave Transpose buttons to shift the entire keyboard's range up or down. This allows you to access a wider range of notes than the 49 physical keys provide.
