One of the first confusing moments in a DAW is realising there are two types of tracks: MIDI and audio. They look similar on screen but behave in completely different ways.
Audio recording
An audio track captures actual sound — a microphone recording your voice, or a guitar plugged into an interface. Once recorded, the waveform is fixed. You can cut it, move it, apply effects, but you cannot change the notes played without re-recording.
MIDI recording
MIDI does not record sound at all. It records instructions: which note was pressed, how hard, and for how long. A MIDI region in your DAW tells a virtual instrument what to play. Change the instrument, and the same MIDI data plays completely different sounds.
Practical comparison
| Feature | Audio | MIDI |
|---|---|---|
| Records | Actual sound waves | Performance instructions |
| Editing notes | Not possible after recording | Edit any note freely |
| File size | Larger | Very small |
| Requires instrument | Microphone or audio interface | Virtual instrument (plugin) |
| Sounds realistic | Yes, by nature | Depends on plugin quality |
Which one should beginners use first
Most bedroom producers start with MIDI because it requires no recording equipment. You draw notes directly into the piano roll or use a cheap MIDI keyboard. The ability to fix mistakes without re-recording removes a lot of early frustration.
Audio becomes essential the moment you want to record a real voice or instrument. Knowing the difference upfront stops a lot of confusion about why one track behaves differently from another.
