5. Installation
5.1 Connexion à un ordinateur (USB)
- Assurez-vous que votre ordinateur est sous tension.
- Connect one end of the supplied USB cable to the USB port on the rear panel of the Origin 37.
- Connectez l’autre extrémité du câble USB à un port USB disponible sur votre ordinateur.
- The Origin 37 is USB class-compliant and does not require special drivers for most operating systems (PC/Mac). It will be powered via the USB connection.
- Turn on the Origin 37 using the Power button on the front panel.
- Your computer should automatically recognize the device. You can then select it as a MIDI input device in your Digital Audio Workstation (DAW) or music software (e.g., Ableton Live).
5.2 Connecting to External MIDI Devices (MIDI OUT)
- Ensure both the Origin 37 and the external MIDI device are powered off.
- Connect a standard 5-pin MIDI cable from the "KEYBOARD MIDI OUT" port on the Origin 37 to the MIDI IN port of your external MIDI device (e.g., synthesizer, sound module).
- Power on the Origin 37, then power on your external MIDI device.
- Configure your external MIDI device to receive MIDI data on the appropriate MIDI channel.
5.3 Connexion d'une pédale de sustain
- Connect a standard 1/4-inch TS (mono) sustain pedal (not included) to the "Sustain Switch" input on the rear panel.
- The pedal will function as a sustain control for your MIDI notes.
6. Mode d'emploi
6.1 Fonctionnement de base
- Jouer des touches : Simply press the keys to send MIDI note-on/note-off messages to your connected software or hardware. The keys are velocity-sensitive, meaning the harder you press, the higher the velocity value sent.
- Molette de variation de ton: Move the wheel up or down to bend the pitch of currently held notes. It automatically returns to the center position.
- Roue de modulation : Move the wheel to apply modulation effects. This wheel typically stays in the position you leave it. The specific effect controlled depends on your software or hardware instrument's settings.
- Bouton de maintien : Press to toggle sustain on or off. When active, notes will continue to sound after the key is released, similar to a piano's sustain pedal.
- Octave Up/Down: Use these buttons to transpose the entire keyboard up or down in octave increments. The LED display will indicate the current octave shift.
- Program Up/Down: These buttons are used to send MIDI Program Change messages, allowing you to switch between different sounds or presets on your connected MIDI device or software.
6.2 Assigning Knobs and Sliders
The 8 knobs and 9 sliders are assignable MIDI controllers. They send MIDI Control Change (CC) messages. The specific CC number each knob/slider sends can be configured. Refer to your software's or hardware's manual for how to map these CC messages to parameters.
To assign a knob or slider:
- Appuyez sur le MIDI/Select button to enter configuration mode.
- Utilisez le Saisie de données slider or Octave Up/Down buttons to navigate through parameters on the LED display.
- Select the desired knob or slider to assign.
- Adjust the value (e.g., MIDI CC number) using the Saisie de données curseur.
- Presse MIDI/Select again to exit configuration mode and save changes.
Note: Specific assignment procedures may vary. Consult the detailed MIDI implementation chart (if available) or your DAW's manual for advanced mapping.
6.3 Data Entry and Display
The LED display provides visual feedback for various settings and parameters. The Saisie de données slider is primarily used to adjust numerical values shown on this display, such as MIDI channel, CC numbers, or program numbers during configuration.
7. Entretien
- Nettoyage: Utilisez un chiffon doux et sec pour nettoyer la surface de l'appareil. N'utilisez pas de nettoyants abrasifs, de cires ni de solvants.
- Stockage: Lorsqu'il n'est pas utilisé pendant une période prolongée, rangez le contrôleur dans un endroit frais et sec, à l'abri de la lumière directe du soleil et des températures extrêmes.
- Manutention: Évitez de laisser tomber l'appareil ou de le soumettre à des chocs violents.
- Pouvoir: Always disconnect the USB cable when the unit is not in use or during electrical storms.
8. Dépannage
| Problème | Cause possible | Solution |
|---|---|---|
| Pas d'alimentation / L'appareil ne s'allume pas. | Câble USB non connecté ou défectueux. | Ensure USB cable is securely connected to both the controller and a powered USB port. Try a different USB port or cable. |
| No sound from software/hardware. | MIDI input not selected in software; incorrect MIDI channel; software instrument not loaded. | Verify the Origin 37 is selected as a MIDI input device in your DAW. Check that the MIDI channel on the controller matches the receiving channel of your software/hardware. Ensure a sound-generating instrument is loaded and active. |
