4. Prodotto finitoview

The Sequential OB-6 is a 6-voice polyphonic analog synthesizer featuring a pure analog signal path, two voltage-controlled oscillators (VCOs) per voice, a state-variable filter, and a suite of digital effects. Its intuitive front panel provides direct, hands-on control over all parameters.

4.1 Controlli del pannello frontale

The front panel is logically laid out into sections for Oscillators, Mixer, Filter, Envelopes, LFO, Modulation, Effects, Sequencer, and Output. Each section features dedicated knobs and switches for immediate sound shaping.

5. Impostazione

5.1 Disimballaggio e posizionamento

Carefully remove the OB-6 from its packaging. Place the synthesizer on a stable, flat surface, ensuring sufficient space for ventilation around the unit.

5.2 Collegamento di alimentazione

1. Ensure the OB-6 power switch is in the OFF position.
2. Connect the provided power supply to the power input on the rear panel of the OB-6.
3. Collegare l'alimentatore a una presa CA adatta.

5.3 Collegamenti audio

Connect the main audio outputs (Right/Mono, Left) on the rear panel to your mixer, audio interface, or amplifier using standard 1/4-inch TS cables. For stereo operation, connect both Left and Right outputs. For mono, use the Left/Mono output.

5.4 Connessioni MIDI e USB

The OB-6 supports both traditional MIDI (DIN connectors) and USB MIDI for communication with computers or other MIDI devices.

• Italiano: Connect MIDI OUT of your controller/interface to MIDI IN of the OB-6. Connect MIDI OUT of the OB-6 to MIDI IN of your other devices or interface.
• USB: Connect a USB Type A cable from the OB-6's USB port to a USB port on your computer. The OB-6 will appear as a MIDI device in your operating system and DAW.

6. Istruzioni per l'uso

6.1 Accensione/Spegnimento

To power on the OB-6, flip the power switch on the rear panel to the ON position. The display will illuminate, and the synthesizer will initialize. To power off, flip the switch back to the OFF position. Always power off the unit before disconnecting the power supply.

6.2 Basic Sound Generation

The OB-6's sound engine is based on two voltage-controlled oscillators (VCOs) per voice, a sub-oscillator, a noise generator, a mixer, a state-variable filter, and two envelopes (filter and amplificatore).

• Oscillatori: Use the OSCILLATORS section to select waveform (saw, pulse), adjust frequency, and fine-tune.
• Miscelatore: The MIXER section blends the levels of OSC 1, OSC 2, Sub, and Noise.
• Filtro: The FILTER section controls the cutoff frequency, resonance, and envelope amount. The OB-6 features a 2-pole, state-variable filter with low-pass, high-pass, band-pass, and notch modes.
• Buste: The FILTER ENVELOPE and LOUDNESS ENVELOPE sections control the attack, decay, sustain, and release stages for dynamic sound shaping.

6.3 Gestione del programma

The OB-6 stores a large number of factory and user programs (presets). Use the BANK and PROGRAM buttons to navigate and select programs. To save a modified program, press the WRITE button, select a destination, and press WRITE again to confirm.

6.4 Modulazione

The MODULATION section provides control over the LFO (Low Frequency Oscillator) and its routing to various destinations, as well as aftertouch and velocity assignments for expressive control.

6.5 Sezione Effetti

The EFFECTS section offers a range of digital effects including reverbs, delays, chorus, flanger, and phase shifter. Use the dedicated controls to select effect type and adjust parameters.

6.6 Sequencer e Arpeggiatore

The OB-6 includes a polyphonic step sequencer and an arpeggiator. Refer to the dedicated sections in the full manual for detailed instructions on programming and using these features.

6.7 Impostazioni globali

The GLOBAL section allows access to system-wide settings such as MIDI channels, tuning, and other preferences. Press the GLOBAL button to enter the global menu and use the data encoder to navigate and adjust parameters.

7. Manutenzione

7.1 Pulizia

To clean the OB-6, disconnect it from power. Use a soft, dry, lint-free cloth to wipe down the chassis and keys. Avoid using abrasive cleaners, solvents, or waxes, as these can damage the finish and components.

7.2 Conservazione

When not in use, store the OB-6 in a clean, dry environment away from direct sunlight and extreme temperatures. If transporting the unit, use a dedicated case to protect it from physical damage.

8. Risoluzione Dei Problemi

This section addresses common issues you might encounter with your OB-6.

• Nessun suono:
  • Controllare il collegamento elettrico e assicurarsi che l'unità sia accesa.
  • Verify audio cables are correctly connected to outputs and your sound system.
