3.セットアップガイド
3.1 開梱と初期検査
Carefully remove the ESI Xsynth from its packaging. Inspect the unit for any signs of damage that may have occurred during transit. Retain the packaging for future transport or storage.
3.2 Powering the Xsynth
The ESI Xsynth is powered via its USB-C port. Connect the provided USB-C cable to the Xsynth's USB-C port and the other end to a compatible USB power adapter (not included) or a computer's USB port. The unit will power on automatically.
3.3 Connecting Audio and MIDI
The Xsynth offers various audio and MIDI connectivity options:
- USB-C: For combined power, audio, and MIDI communication with a computer.
- DIN MIDI In/Out: Use standard 5-pin MIDI cables to connect to external MIDI devices.
- Headphones (3.5mm): Connect stereo headphones for private monitoring.
- ライン出力 (3.5mm): 接続する amplifier, mixer, or audio interface for stereo output.
- Aux In (3.5mm): Connect external audio sources to be processed or mixed with the Xsynth's output.

4. Operating the Xsynth
4.1 基本的な操作とナビゲーション
The Xsynth features a streamlined interface for intuitive control. Key elements include:
- ノブ: Control various parameters such as oscillator settings, filter cutoff, and effect levels.
- ボタン: Used for patch selection, mode switching (e.g., OSC, ENV, LFO, MACRO, MIX, GLOBAL), and activating performance features.
- 画面: A small screen provides visual feedback on current parameters and settings.
- ナビゲーションボタン: "PAGE", "ENTER", "GLOBAL", and "SELECT" buttons facilitate menu navigation and parameter adjustment.

4.2 Synthesizer Parameters
The Xsynth's virtual analog engine allows for extensive sound shaping:
- Oscillators (OSC): Adjust waveform, pitch, and other characteristics of the 3 oscillators.
- Envelopes (ENV): Shape the amplitude, filter, or pitch over time using the 3 AHDSR envelopes.
- LFO: Modulate parameters with the 3 Low-Frequency Oscillators.
- Modulation Matrix: Utilize the 16 mod matrix slots to assign modulation sources to destinations.
- エフェクト(FX): Apply built-in effects and adjust their parameters.
- EQ: Fine-tune the tonal balance of your sounds.
4.3 Keyboard and Performance Features
The 25 touch-sensitive keys provide a responsive playing experience. Enhance your performance with:
- ポリフォニックアフタータッチ: Apply pressure to individual keys after striking them to modulate sound.
- アルペジエーター: Create rhythmic patterns from held notes.
- グライド: Smoothly transition between notes.
- オクターブシフト: Transpose the keyboard range up or down.
- 所有: Sustain notes without continuously holding down keys.
- Modulation and Pitchbend Buttons: Pressure-sensitive buttons for expressive control over pitch and other parameters.
5. メンテナンス
To ensure the longevity and optimal performance of your ESI Xsynth, follow these maintenance guidelines:
- クリーニング: Use a soft, dry cloth to wipe down the unit. For stubborn dirt, slightly damp布を水で拭いてください。研磨剤入りの洗剤や溶剤は使用しないでください。
- ストレージ: Store the Xsynth in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
- 取り扱い: Avoid dropping the unit or subjecting it to strong impacts. Do not place heavy objects on top of the Xsynth.
- 接続性: Always handle cables by their connectors, not by the cable itself, to prevent damage to the ports and cables.
6。 トラブルシューティング
If you encounter issues with your ESI Xsynth, refer to the following common problems and solutions:
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| 電源なし | USB-C cable not connected properly or power source issue. | Ensure the USB-C cable is securely connected to both the Xsynth and the power source. Try a different USB port or power adapter. |
| 音声出力なし | Volume too low, incorrect audio output selected, or cable issue. | Check the master volume on the Xsynth. Ensure your headphones or speakers are connected to the correct output (Line Out/Phones) and are powered on. Verify audio settings on your computer if using USB audio. |
| MIDIが動作しない | Incorrect MIDI connections or software settings. | Verify DIN MIDI cables are connected correctly (Out to In, In to Out). Check MIDI settings in your DAW or external MIDI device. Ensure USB MIDI drivers are installed if required (usually class-compliant). |
| キーが応答しない | Unit frozen or internal issue. | Try power cycling the unit (unplug and replug USB-C). If the issue persists, contact customer support. |
If the problem persists after attempting these solutions, please contact ESI customer support for further assistance.
