The C1, C2, and C3 knobs are often assignable, allowing you to customize your workflow. The Volume knob controls the overall output level. The Tempo knob adjusts the master tempo for sequencers and LFOs. The Pitchbend knob allows for real-time pitch modulation.
- Display Screen: The central display shows detailed information about the selected engine, oscillator parameters (e.g., Saw Mix, Square Mix, Sub Mix, Noise, PW, Sub Mode, Pitch LFO, PW Env, PW LFO), and other settings.
- Filter Section: Access the filter parameters using the Filter button to shape the timbre of your sounds.
- ADSR Envelope: The ADSR button provides access to the Attack, Decay, Sustain, and Release envelope parameters, crucial for shaping the amplitude of your sounds.
- LFO (Low-Frequency Oscillator): Use the LFO button to control low-frequency modulation sources for adding movement and texture to your patches.
- Mixer Effects: The Mixer Effects button allows access to built-in effects to further enhance your sound.
- Scene/Preset Management: The Scene Preset button enables saving and recalling your custom sounds and performance setups.
