What is MIDI and how does it work in GarageBand?
MIDI, or Musical Instrument Digital Interface, is a protocol that allows electronic musical instruments, computers, and other devices to communicate with each other. In GarageBand, MIDI is used to control virtual instruments, such as software synthesizers and drum machines. When you create a MIDI region in GarageBand, you are essentially creating a set of instructions that tell the virtual instrument what notes to play, how loud to play them, and how long to sustain them. This allows for a high degree of control and flexibility when it comes to editing and customizing your music.
To work with MIDI in GarageBand, you don’t need any external hardware, as the software includes a wide range of virtual instruments that can be controlled using MIDI. You can create MIDI regions by recording live performances using a MIDI keyboard or by drawing in notes and controller data using the GarageBand editor. Once you have created a MIDI region, you can edit it using a variety of tools and techniques, such as quantizing, transposing, and adjusting the velocity and duration of individual notes. This allows you to refine and perfect your performances, and to create complex and nuanced musical arrangements.
