3. Operating the Axiom 25
3.1 Key Features and Controls
- 25 Semi-Weighted Keys: Provide a responsive playing experience with a feel similar to a traditional piano.
- Assignable Aftertouch: Allows for expressive control over sounds by applying pressure to the keys after initial press.
- 8 Rubberized Trigger Pads: Ideal for drum programming, sample triggering, and launching clips.
- Rotary Encoder Knobs: Control synth parameters, virtual mixer controls, and other MIDI-assignable functions.
- 6 Transport Controls: Can be assigned to control various MIDI parameters, such as DAW transport functions (play, stop, record, etc.).
3.2 Basic Functions
- Octave and Transpose Buttons: Adjust the keyboard's octave range and transpose notes up or down.
- Preset, Program Change, MIDI Channel Buttons: Navigate and select presets, send program change messages to software/hardware, and adjust the MIDI channel for communication.
- Memory Locations: Store up to 20 non-volatile memory locations for custom setups and configurations.
- Memory Dump via Sys Ex: Transfer memory settings to and from a computer using System Exclusive (Sys Ex) messages.
- Controller Mute Function: Temporarily mutes the output of controllers to prevent parameter jumps when changing settings or presets.
- Snapshot Function: Transmits all current controller settings to the connected device.
- Backlit LCD Display: Provides clear visual feedback for programming, navigation, and parameter values.
- On/Off Rocker Switch: Powers the unit on or off.
3.3 MIDI Assignability
Virtually all controls on the Axiom 25 are freely MIDI-assignable. This allows for extensive customization to suit your specific software and hardware setup, enabling you to map knobs, pads, and buttons to control various parameters in your digital audio workstation (DAW) or external MIDI devices.
4. Maintenance
- Keep the controller clean by wiping with a soft, dry cloth. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and components.
- Protect the unit from dust, moisture, and extreme temperatures. Do not expose it to direct sunlight or heat sources.
- Do not place heavy objects on the controller, as this may damage the keys or internal components.
- When not in use, consider covering the controller to prevent dust accumulation.
5. Troubleshooting
- No Power: Ensure the USB cable is securely connected to both the controller and the computer. If using an optional power supply, verify it is correctly connected and functioning. Check the On/Off rocker switch.
- Not Recognized by Computer/Software: Verify that the correct drivers are installed for your operating system. Check the integrity of the USB cable. Ensure the controller is powered on. Consult your DAW's MIDI setup guide to ensure the Axiom 25 is enabled as a MIDI input device.
- No Sound: Confirm that the MIDI output from the Axiom 25 is routed correctly to a sound source (e.g., a software instrument in your DAW or an external synthesizer). Ensure the sound source is active and its volume is audible.
- Unexpected Parameter Jumps: Utilize the Controller Mute function before adjusting controls or changing presets to prevent sudden changes in sound or parameter values.
- Keys/Pads Not Responding: Check MIDI channel settings on both the controller and your software/hardware. Ensure no conflicting MIDI messages are being sent.
