Here's an example of how MIDI works:
Imagine you have a MIDI keyboard connected to your computer. When you press a key on the keyboard, it sends a MIDI message to the computer. This message contains information about the note you played, such as its pitch, velocity (how hard you pressed the key), and duration.
The computer receives the MIDI message and interprets it based on the software or digital audio workstation (DAW) you are using. For instance, if you have a synthesizer software open, the computer will play the corresponding note on the synthesizer using its internal sound engine. Alternatively, if you have a sampler loaded with different instrument sounds, the computer will trigger the appropriate sample to play.
As you play more notes on the MIDI keyboard, the computer continues to receive and interpret the MIDI messages, creating a sequence of notes that represent your musical performance. You can then edit and manipulate this MIDI sequence using your DAW, such as changing the notes, adding effects, or adjusting the tempo.
Moreover, MIDI not only allows you to play and record music but also enables synchronisation between different devices and software. This means you can use MIDI to connect multiple instruments, such as keyboards, drum machines, and samplers, and have them play together in perfect sync. Additionally, MIDI can control other parameters, such as lighting and stage effects, creating interactive and dynamic musical performances.
Overall, MIDI acts as a universal language that facilitates the communication and exchange of musical data between different electronic devices and software, providing a powerful tool for musicians, producers, and sound designers to create, record, and perform music.
