Using MIDI controllers involves connecting the controller to your Digital Audio Workstation (DAW) or music production software via MIDI .

Here is a general overview of how to use MIDI controllers in your music production:
Connect the MIDI controller to your computer
Use a USB cable to connect the MIDI controller directly to your computer’s USB port. If your MIDI controller does not have a USB connection, you can use MIDI cables to connect it to an audio interface or MIDI interface that is connected to your computer.
Configure the MIDI controller in your DAW
Open your DAW and go to the settings or preferences menu to set up your MIDI controller. Select the MIDI input and output ports that correspond to your controller. Many DAWs have automatic detection for MIDI controllers, making the setup process easier.
Assign MIDI functions
In your DAW, you can assign various functions of the MIDI controller to control parameters within the software. This can include triggering clips, adjusting faders and knobs, playing virtual instruments, recording MIDI data, or activating effects. Most DAWs allow for MIDI mapping, where you can assign specific functions to different controls on your MIDI controller.
Start playing and experimenting
Once your MIDI controller is set up and mapped in your DAW, you can start using it to create and perform music. Play notes on virtual instruments using the keys or pads on your MIDI controller, adjust parameters in real-time using faders and knobs, or trigger samples and loops for live performances.
Overall, using MIDI controllers adds a tactile and interactive element to your music production, allowing for more expressive and dynamic control over your sounds and performances. Experiment with different MIDI controllers, mappings, and techniques to find what works best for your creative process.
