MIDI files contain musical performance data – sequences of recorded notes programmed to use the standard set of 128 General MIDI sounds found on most PC soundcards. By importing the data into GarageBand, you can reproduce a performance by assigning your own choice of GarageBand’s built-in software instrument sounds to the individual MIDI parts. The beauty of this system is that you can dissect MIDI parts and assign better sounds to them, creating something that sounds closer to or even better than the original. This means you have the freedom to rework your favourite tunes into something really special. Let’s get searching!
