4. Driver Installation (Windows): If your Windows computer does not recognize the MPC-20, it may be installing the necessary driver. If issues persist, please refer to the DOREMiDi website for the latest drivers and firmware update instructions.

5. Betjening

Once connected, the MPC-20 converts the physical input from your pedals into MIDI messages. These messages are then sent to your connected computer or MIDI device via USB or MIDI DIN. The specific function of each pedal (e.g., volume, modulation, sustain) will depend on how your receiving MIDI device or software is configured to interpret the incoming MIDI messages.

• Expressionspedaler: Typically send Continuous Controller (CC) messages, allowing for real-time control over parameters like volume, wah, or modulation.
• Sustain Pedals: Send MIDI Note On/Off messages or CC messages (e.g., CC 64 for sustain) to control sustain functions on keyboards or synthesizers.
• Dual-Switch Pedals: Each switch can be configured to send distinct MIDI messages, often used for program changes, tap tempo, or other on/off functions.

For advanced configuration, such as assigning specific MIDI channels or CC numbers to each pedal input, you may need to use the dedicated software provided by DOREMiDi. Refer to the software's documentation for detailed instructions.

6. Vedligeholdelse

• Hold enheden ren og fri for støv. Brug en blød, tør klud til rengøring.
• Undgå at udsætte enheden for ekstreme temperaturer, fugt eller direkte sollys.
• Forsøg ikke at adskille eller ændre enheden, da dette vil ugyldiggøre garantien og kan forårsage skade.
• Sørg for, at alle forbindelser er sikre inden brug.

7. Fejlfinding

• Enhed genkendes ikke af computeren:
  • Ensure the USB cable is securely connected to both the MPC-20 and your computer.
  • Prøv en anden USB-port på din computer.
  • For Windows users, check the DOREMiDi website for the latest USB COM drivers and installation instructions.
  • Restart your computer and the MPC-20.
• No MIDI Output:
  • Verify that your pedals are correctly connected to the EXP inputs.
  • Check the MIDI connections (USB or DIN) to your receiving device.
  • Ensure the receiving MIDI device or software is correctly configured to receive MIDI messages on the appropriate channel and controller numbers.
  • If using the DOREMiDi configuration software, ensure the settings are correctly applied and saved to the device.
• Inconsistent Pedal Response / Dropouts:
  • Ensure the power supply is stable. If using a USB hub, try connecting directly to the computer or using a powered hub.
  • Check the condition of your pedal cables. Faulty cables can cause intermittent issues.
  • Verify that the pedals themselves are functioning correctly.
  • Consider updating the MPC-20 firmware if available. Refer to the DOREMiDi website for firmware updates and instructions. Note that firmware updates often require specific software.
• Softwarekonfigurationsproblemer:
  • Always download the newest version of the DOREMiDi configuration software from the official webwebsted.
  • If the software interface is unclear, consult the software's specific documentation or online resources.
  • Ensure the software can communicate with the MPC-20. Sometimes, a firmware update through the software itself is required before full functionality is achieved.
