6. 操作手順

6.1 Playing Notes

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.

• 割り当て： 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.
• 一般的な用途: Control volume, pan, filter cutoff, resonance, effect send levels, or any other MIDI-mappable parameter.

6.3 ピッチベンドとモジュレーションホイール

• ピッチベンドホイール： 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.
• モジュレーションホイール： 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.

• Press the "Octave Up" button to shift the keyboard's range higher.
• Press the "Octave Down" button to shift the keyboard's range lower.
• The Radium 49 supports up to +/-3 octave transposition.

7. メンテナンス

• クリーニング： Use a soft, dry, lint-free cloth to clean the surface of the Radium 49. Do not use abrasive cleaners, waxes, or solvents.
• ストレージ： When not in use for extended periods, store the device in a clean, dry environment, away from direct sunlight and extreme temperatures.
• 取り扱い： Avoid dropping or subjecting the device to strong impacts. Do not place heavy objects on the keyboard.

8。 トラブルシューティング

8.1 No Sound or MIDI Output

• USB接続を確認してください: Ensure the USB cable is securely connected to both the Radium 49 and your computer. Try a different USB port or cable.
• ドライバーの確認: Confirm that the correct drivers are installed and recognized by your operating system. Check Device Manager (Windows) or System Information (macOS) for the device status.
• DAW/ソフトウェア設定: Ensure the Radium 49 is selected as a MIDI input device in your music software's preferences. Verify that the track you are playing on is armed for recording or monitoring MIDI input.
• Software Instrument Loaded: Make sure a software instrument or sound generator is loaded and active in your DAW.

8.2 Inconsistent Velocity Sensitivity or Key Response

• クリーニング： Dust or debris under the keys can affect performance. Refer to the maintenance section for cleaning guidelines.
• ソフトウェア設定： Check if your DAW or instrument has velocity curve settings that might be affecting the response.

8.3 Compatibility Issues with Newer Operating Systems

The M-Audio Radium 49 is an older model. While it may function with newer operating systems, full compatibility and driver support can be limited. If you encounter issues:

• Check M-Audio Support: M-Audioをご覧ください website for any legacy driver updates or compatibility statements.
• コミュニティフォーラム: Search online forums for solutions or workarounds from other users who have successfully used the Radium 49 with your operating system.
• Consider a MIDI Interface: In some cases, using a separate, modern USB-to-MIDI interface to connect the Radium 49's MIDI Out port to your computer might resolve driver-related issues, though this would bypass the direct USB MIDI functionality.
