Setup
1. Unboxing and Inspection
Carefully remove all components from the packaging. Verify that all included items are present:
- Roland JUPITER-X 61-key Synthesizer
- Real-feel Sustain Pedal
- Roland 10ft MIDI Cable
- Roland 10ft Microphone Cable
- Power Cable (not explicitly listed but implied for a synthesizer)
- User Manual (this document)
Inspect the synthesizer and accessories for any signs of damage during transit. If any items are missing or damaged, contact your retailer immediately.
2. Connecting the Synthesizer
Before connecting, ensure the JUPITER-X and all connected devices are powered off.
- Power Connection: Connect the power cable to the AC IN jack on the rear panel of the JUPITER-X, then plug the other end into a suitable AC outlet.
- Audio Output: Connect the JUPITER-X's OUTPUT (L/MONO, R) jacks to your mixer, audio interface, or amplifier using appropriate audio cables.
- Sustain Pedal: Connect the included sustain pedal to the HOLD jack on the rear panel.
- MIDI Connections: Use the included Roland 10ft MIDI cable to connect the JUPITER-X to other MIDI devices (e.g., a computer's MIDI interface or another synthesizer). Connect the MIDI OUT of the JUPITER-X to the MIDI IN of the external device, and vice-versa if bi-directional communication is desired.
- Microphone Input: If using a microphone, connect it to the MIC INPUT jack. The included Roland 10ft Microphone Cable can be used for this purpose.

3. I-Arpeggio Functionality
The I-Arpeggio is a next-generation arpeggiator that uses artificial intelligence to generate complementary musical parts. It analyzes your input (notes, rhythms, phrases) and creates drum parts, bass lines, chords, and arpeggiated lines across the JUPITER-X's five parts simultaneously. Generated patterns can be customized and exported to your DAW for further refinement.
4. Layering and Polyphony
The JUPITER-X supports multiple layers and offers extensive polyphony, allowing you to create rich, complex sounds. Utilize the Part Select buttons to manage and manipulate individual sound layers, building intricate textures and arrangements.
