MIDI (Musical Instrument Digital Interface) is a universal protocol that allows electronic instruments and computers to communicate. It does not transmit audio signals; instead, it sends data instructions—such as which note was played, how hard it was hit, and how long it lasted—to trigger sounds from software instruments or hardware synths.
- 1.Connect a MIDI controller (like a keyboard or pad controller) to your computer via USB or a MIDI interface.
- 2.Load a Virtual Instrument (VST/AU) onto a MIDI track within your Digital Audio Workstation (DAW) to generate sound.
- 3.Record your performance into the DAW's piano roll, where it will appear as blocks representing pitch, duration, and velocity.
- 4.Use the MIDI editor to quantize (align notes to the grid) or manually move notes to fix timing and melodic errors.
- ×MIDI cables and USB connections do not carry sound; you will not hear anything unless the MIDI data is sent to a sound engine or virtual instrument.
- ×Double-check your 'MIDI Input' settings in your DAW preferences if your controller isn't triggering sounds.
- ×High 'Buffer Size' settings in your audio interface can cause latency, making it difficult to play MIDI instruments in real-time.
Think of MIDI as 'digital sheet music.' Since it contains no actual audio, you can change the instrument (e.g., from a piano to a violin) or fix a wrong note long after the performance has been recorded.
