When you launch the GarageBand app, it will prompt you to begin a New Project.
You have four options:
A MIDI device stands for Musical Instrument Digital Interface. Basically you can use a MIDI keyboard to create sounds other than a keyboard piano. The audio function allows you to record with a microphone or an electric guitar or bass (because they have pick-ups or an amp that amplify sound). And finally, the drummer feature: a virtual drummer to create beats with and maintain the tempo.
This option allows you to write music using a MIDI instrument (for example, a MIDI keyboard like the AKAI available in our library collection) or the virtual keyboard within the program.
Recording audio will require an audio interface. In simple terms, it helps convert the analog signal of your instrument into a digital signal for your DAW (digital audio workstation).
Many times, you might want to begin your project with a drum beat. Choose from a wide selection of drummer styles and instruments. The drummer feature also allows you to vary the simplicity and complexity of the beat using a toggle.
