Operating Instructions
Familiarize yourself with the various controls and functions of your MIDI controller:
- 25 Sim-Keys: These velocity-sensitive keys respond to how hard you press them, allowing for dynamic expression. Use them to play melodies, chords, and other musical parts.
- 8 RGB Pads: The pads are velocity-sensitive and can be used to trigger drums, samples, or other sounds. Their RGB lighting provides visual feedback.
- OLED Display: This display shows current settings, parameters, and feedback from your interactions with the controller. Use it to navigate menus and confirm selections.
- 360° Endless Knob & 8 Assignable Knobs: The endless knob and the eight assignable knobs can be mapped to various parameters within your DAW or software instruments, allowing for real-time control over sound characteristics like filter cutoff, resonance, or effects.
- Arpeggiator & Pitch Controller: Utilize the arpeggiator to create rhythmic patterns from held notes. The pitch controller allows for real-time pitch bending and modulation effects.
- Semitone Transposition: Adjust the pitch of the keyboard up or down in semitone increments to easily change keys without altering your playing technique.
- Sustain Pedal: A connected sustain pedal will allow notes to ring out after the keys are released, similar to an acoustic piano.
