6. Bedienungsanleitung
6.1 Keyboard spielen
The 49 mini keys are velocity-sensitive, meaning the volume or intensity of a note can vary based on how hard you press the key. Experiment with different playing dynamics to achieve expressive performances.
6.2 Octave and Transpose Functions
- Oktavtasten: Use the dedicated Octave Up and Octave Down buttons (located near the pitch/mod strips) to shift the keyboard's range up or down in full octaves.
- Transponierungsfunktion: The Octave buttons can also function as Transpose buttons when combined with the SHIFT key. Press and hold the SHIFT button, then use the Octave Up/Down buttons to transpose the keyboard by semitones.
6.3 Pitch Bend und Modulation
- Pitch Touch Strip: Bewegen Sie Ihren Finger entlang dieses Streifens, um die Tonhöhe zu erhöhen oder zu senken. Die Tonhöhe kehrt beim Loslassen in die Mittelstellung zurück.
- Modulation Touch Strip: Slide your finger along this strip to apply modulation effects, such as vibrato or tremolo, to your sound. The specific effect depends on your software or hardware instrument's settings.
6.4 Assignable Knobs (T1-T4)
The four rotary knobs (T1-T4) send MIDI Continuous Controller (CC) messages. By default, these may control common parameters like volume or pan in your DAW. You can reassign these knobs to control specific parameters within your software instruments or effects.
- Consult your DAW or software instrument's manual for instructions on how to MIDI-learn or assign CC messages to parameters.
- The X4 mini also allows for on-the-fly reassignment of the CC messages sent by these knobs. Refer to the "Advanced Features" section for details.
7. Erweiterte Funktionen
7.1 Reassigning MIDI CC Messages for Knobs
The Midiplus X4 mini allows you to customize the MIDI CC messages sent by the T1-T4 knobs. This enables you to control a wider range of parameters in your software or hardware.
- Halten Sie die SCHICHT Taste.
- While holding SHIFT, press one of the function buttons (often labeled with CC numbers or functions) corresponding to the knob you wish to reassign.
- Use the keyboard keys to input the desired MIDI CC number. The specific keys for number input will be indicated on the keyboard itself or in a quick reference guide.
- Drücken Sie die EINGEBEN or SCHICHT button again to confirm the assignment.
Note: The exact procedure for CC reassignment may vary slightly. Refer to the markings on your specific unit for precise key combinations.
