Operating the LX49+
1. Keyboard Keys
The LX49+ features 49 full-size, velocity-sensitive synth-action keys. Velocity sensitivity means the volume or intensity of a note changes based on how hard you press the key, allowing for expressive performances.
2. Control Elements
The controller is equipped with various assignable controls:
- 9 Faders: These 30mm faders are typically used for mixer volume control in your DAW or for adjusting instrument parameters.
- 8 Rotary Knobs: These knobs provide continuous control over various parameters, often assigned to instrument filters, effects, or other sound shaping functions.
- 8 Backlit Drum Pads: Velocity-sensitive pads ideal for finger drumming, triggering samples, or launching clips. They are backlit for visual feedback.
- Octave & Transpose Buttons: Dedicated buttons allow you to shift the keyboard's octave range up or down, or transpose the pitch in semitone steps.
- Pitch Bend & Modulation Wheels: Standard controls for expressive performance, allowing for pitch variations and modulation effects.
- 6 Transport Buttons: Dedicated buttons for controlling DAW functions like Play, Stop, Record, Fast Forward, and Rewind.

3. DAW Integration Features
Nektar's DAW integration provides intelligent mapping of the LX49+'s controls to your software. This includes:
- Mixer Mode: Faders and knobs automatically control mixer channels (volume, pan, sends) in your DAW.
- Instrument Mode: Controls are mapped to parameters of virtual instruments, allowing for hands-on sound design.
- Transport Control: Play, Stop, Record, and other transport functions are directly accessible.
Consult the Nektar DAW Integration guide (available on the Nektar website) for detailed instructions on specific DAW setups and advanced mapping options.
Maintenance
To ensure the longevity and optimal performance of your Nektar Impact LX49+:
