When to use it
Use MIDI when you need to represent musical data digitally, rather than working with raw audio. MIDI unlocks capabilities for tasks like editing note sequences, controlling virtual instruments, and synchronizing music events across devices.
Quick example
In Apple's Logic Pro, a musician can compose a piece using a MIDI keyboard to input notes. The MIDI data is then used to control virtual instruments within the software, allowing for easy manipulation of pitch, tempo, and instrument sounds. Logic Pro includes MIDI as a core component, enabling seamless integration with both hardware and software instruments.
Ecosystem
MIDI operates within a broader music production ecosystem, interacting with both hardware and software components.
MIDI keyboard → MIDI interface → DAW (Digital Audio Workstation) → audio output
Misconceptions
| Misconception | Rebuttal |
|---|---|
| MIDI transmits audio | MIDI transmits musical data, not audio signals |
| MIDI is outdated | MIDI remains a standard in modern music production |
| MIDI files are large | MIDI files are compact, containing only musical instructions |
Trade-offs
- Flexibility — limited to musical data, not audio
- Interoperability — requires compatible devices and software
- Precision — lacks the nuance of live audio recordings
