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. Operasie

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.

• Expression Pedals: 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.
