2. Install Ableton Live Lite using the provided software or by downloading it from the official website as instructed in the included documentation.
3. For optimal performance, ensure your operating system and any music software are up to date.

4. Operating the Keyrig 25

4.1. Basic Controls

• Keys: The 25 velocity-sensitive keys respond to how hard you press them, affecting the volume or intensity of the sound.
• Pitch Bend Wheel: Located on the left, this wheel allows for real-time pitch modulation of notes.
• Modulation Wheel: Also on the left, this wheel typically controls vibrato or other assignable modulation effects.
• Volume Slider: An assignable slider that can control the master volume or other parameters within your software.
• Assignable Knobs and Buttons: The 8 knobs and 8 buttons can be mapped to various parameters in your software, such as filter cutoff, resonance, effect sends, or patch changes. Refer to your software's MIDI mapping instructions for configuration.

4.2. KeyRig Software Modules (PC Only)

The included KeyRig software provides a suite of virtual instruments:

• SP-1 Stage Piano: Offers grand pianos, Wurlitzer, classic electric pianos, FM, clavinet, and more. Each preset supports two instruments with individual settings for Mix, Octave, Detune, Velocity, and Tone, plus a dual effects section.
• MS-2 Polyphonic Synthesizer: Provides an intuitive way to create and edit synth sounds. Presets consist of sub-presets for filter, amp, mod, and FX sections, allowing for easy sound design.
• MB-3 Tone Wheel Organ: Authentically emulates the classic Hammond sound with a rotary speaker. Features include nine drawbars (pre-mapped to M-Audio controllers), percussion, variable key click, and chorus/vibrato settings.
• GM-4 General MIDI Module: Delivers 128 GM instruments and a GM drum kit, ideal for playing GM-compatible standard MIDI files and sequencing backing tracks.

4.3. Effects, Mixing, and Assignment

Each KeyRig module features its own dual effects processors (delay, chorus, phaser, etc.). A master effects section processes the combined output of all modules. The internal mixer and assignment controls allow for independent MIDI channels for each module, enabling splits and layers (e.g., left-hand bass with right-hand keys, piano/string layers).

4.4. Integration with DAWs

The Keyrig 25 and KeyRig software can be used as standalone instruments or integrated with most host sequencers. Compatibility with AU, VST, and RTAS formats allows use as sound sources in popular music software such as Pro Tools, Logic, Cubase, and Ableton Live.

5. Maintenance

Proper care ensures the longevity and optimal performance of your Keyrig 25.

5.1. Cleaning

• Use a soft, dry, lint-free cloth to wipe down the surface of the controller.
• For stubborn dirt, slightly dampen the cloth with water. Avoid abrasive cleaners, solvents, or waxes.
• Do not spray liquids directly onto the unit.

5.2. Storage

• Store the Keyrig 25 in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
• Protect the keys and controls from dust and debris when not in use, ideally with a dust cover.
• Avoid placing heavy objects on the keyboard.

6. Troubleshooting

If you encounter issues with your Keyrig 25, refer to the following common solutions:

• No Sound/No MIDI Output:
  • Ensure the USB cable is securely connected to both the Keyrig 25 and your computer.
  • Verify that the Keyrig 25 is recognized by your operating system's device manager (Windows) or Audio MIDI Setup (Mac).
  • Check your music software's MIDI input settings to ensure the Keyrig 25 is selected as an active input device.
  • Confirm that the volume slider on the Keyrig 25 is not at its minimum setting and that your software's output volume is audible.
• Software Compatibility Issues:
  • While the Keyrig 25 hardware is generally compatible with Windows XP and Mac OS X, the included KeyRig software is specifically for PC. Ensure you are using the correct software for your operating system.
  • For newer operating systems, check the M-Audio website for updated drivers or compatibility information.
• Controls Not Responding:
  • Ensure the controls (knobs, buttons, sliders) are correctly mapped within your music software. Refer to your software's documentation for MIDI mapping instructions.
  • Restart your computer and the Keyrig 25.
