3. Setup Guide
Follow these steps to set up your Midiplus AKM322:
- Unpacking: Carefully remove the AKM322 from its packaging. Ensure all components, including the USB cable, are present.
- Power Connection: The AKM322 is primarily USB powered. Connect the included USB cable from the AKM322's USB Type-B port to an available USB port on your computer (PC or Mac). The device will power on automatically.
- Driver Installation: The AKM322 is a class-compliant MIDI device and typically does not require specific drivers for basic functionality on most operating systems (Windows, macOS). Your computer should recognize it automatically. If issues arise, check the Midiplus website for any available drivers or firmware updates.
- Software Configuration: Open your preferred Digital Audio Workstation (DAW) or music software. Navigate to the MIDI settings or preferences. The AKM322 should appear as an available MIDI input device. Select it to enable MIDI communication.
- Optional Sustain Pedal: If using an external sustain pedal (not included), connect it to the 1/4-inch sustain pedal input on the rear of the AKM322.

4. Operating Instructions
This section details the operation of the Midiplus AKM322's various controls and features.
4.1 Basic Playback
Once connected and configured in your DAW, the 32 velocity-sensitive keys will transmit MIDI note data. The velocity sensitivity allows for dynamic expression based on how hard the keys are pressed.
4.2 Pitch and Modulation Wheels
- Pitch Bend Wheel: Located on the left side, this wheel allows for real-time pitch bending of notes. It is spring-loaded and returns to the center position when released.
- Modulation Wheel: Also on the left, this wheel typically controls modulation effects such as vibrato or filter cutoff, depending on your software instrument's mapping. It stays in the position it is set to.
4.3 Octave Buttons
Use the Octave Up and Octave Down buttons to shift the keyboard's pitch range up or down in octaves. This expands the playable range beyond the physical 32 keys.
4.4 Transport Controls
The dedicated transport buttons (Play, Stop, Rec, etc.) can control playback and recording functions within your DAW. These controls are typically MIDI-mappable and may require configuration in your software's MIDI Remote Control or Control Surface settings.
4.5 Arpeggiator, Chord, and Scale Modes
- Arpeggiator: Activates the built-in arpeggiator to generate rhythmic patterns from held notes.
- Chord Mode: Enables the function to trigger full chords with a single key press.
- Scale Mode: Restricts played notes to a selected musical scale, aiding in melodic accuracy.
Refer to your DAW's documentation and the Midiplus MIDI Editor for specific settings and synchronization options for these modes.
4.6 Customization with MIDI Editor
The Midiplus AKM322 features a specially-developed MIDI Editor software (available for PC and Mac from the Midiplus website). This editor allows you to customize the controller's parameters, such as MIDI channel, velocity curves, and button assignments, to suit your individual needs and optimize integration with your specific software.
5. Care and Maintenance
Proper care will ensure the longevity and optimal performance of your AKM322:
- Cleaning: Use a soft, dry cloth to clean the surface of the controller. Avoid abrasive cleaners, solvents, or waxes, as these can damage the finish.
- Storage: Store the AKM322 in a cool, dry place away from direct sunlight, excessive heat, and extreme temperatures.
- Handling: Avoid dropping the device or subjecting it to strong impacts. Do not place heavy objects on the keys or controls.
- Connectivity: Always handle USB cables and other connectors carefully to prevent damage to the ports.

6. Troubleshooting Guide
If you encounter any issues with your AKM322, refer to the table below for common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power or device not recognized by computer. | USB cable not connected properly or faulty; computer USB port issue. | Ensure the USB cable is securely connected to both the AKM322 and your computer. Try a different USB port or cable. Restart your computer. |
| No sound from DAW/software. | MIDI input not enabled in software; incorrect instrument selected; software volume low. | Check your DAW's MIDI settings to ensure the AKM322 is selected as an input device. Verify that a virtual instrument or track is armed for recording and has a sound loaded. Increase software volume. |
| Keys not responding or inconsistent velocity. | Software velocity curve settings; physical obstruction under keys. | Adjust the velocity curve settings in your DAW or using the Midiplus MIDI Editor. Ensure no debris is lodged under the keys. |
| Transport controls (Play, Stop, Rec) not working. | DAW not configured for MIDI transport; incorrect MIDI mapping. | Check your DAW's preferences for MIDI Remote Control or Control Surface settings. Map the AKM322's transport buttons to the corresponding functions in your software. |
| Arpeggiator, Chord, or Scale modes not functioning. | Feature not activated on the controller; incorrect settings in MIDI Editor or DAW. | Ensure the respective mode is activated on the AKM322. Consult the Midiplus MIDI Editor or your DAW's manual for synchronization and specific settings. |
