5.2 Using Knobs, Sliders, and Buttons
Once connected, your operating system should recognize the EasyControl.9 as a standard MIDI device. In your Digital Audio Workstation (DAW) or music software, navigate to the MIDI settings or controller setup section. Here, you can assign the physical controls (knobs, sliders, buttons) on the EasyControl.9 to various parameters within your software, such as volume, pan, filter cutoff, effect sends, and more. Refer to your software's manual for specific instructions on MIDI mapping.
5.3 Transport Controls
The 6 transport buttons (Rew, Play, FF, Loop, Stop, Rec) are typically pre-mapped in most DAWs to control playback and recording functions. If they do not function automatically, you may need to enable MIDI Machine Control (MMC) or assign them manually in your software's preferences.
5.4 Assignable Buttons
The two assignable buttons can be programmed to send specific MIDI Control Change (CC) messages. This allows for custom functions or toggles within your software. Consult your DAW's MIDI mapping features to configure these buttons to your desired parameters.
5.5 Memory Banks
The 4 programmable memory banks allow you to store different sets of MIDI assignments. This is useful for quickly switching between various instrument setups or project configurations without having to re-map controls each time. Refer to the device's specific programming instructions (if available, or your DAW's controller setup) to utilize these banks effectively.

6. Maintenance
6.1 Cleaning
To clean the controller, use a soft, dry cloth. Do not use abrasive cleaners, solvents, or waxes, as these may damage the finish or internal components.
6.2 Storage
When not in use, store the controller in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, consider placing it in its original packaging or a protective case.
7. Troubleshooting
- Controller not recognized by computer:
- Ensure the USB cable is securely connected to both the controller and the computer.
- Try connecting to a different USB port on your computer.
- Restart your computer and try again.
- Verify that your operating system is up to date.
- No sound or control in music software:
- Check your DAW's MIDI settings to ensure the EasyControl.9 is selected as an active MIDI input device.
- Confirm that the tracks or instruments you are trying to control are configured to receive MIDI input from the controller.
- Ensure that the correct MIDI channels are being used if your software or instrument requires specific channel assignments.
- Controls not responding as expected:
- Verify your MIDI mapping within your music software. Controls may need to be assigned manually.
- Check if the controller is in the correct memory bank if you are using custom configurations.
