How to Convert Midi File Instruments in Garageband

The Midi file format may not be what you find in your iTunes library, but it has a long history in the world of digital sound. The Midi file format has been important in the world of computer music since the 1980’s. While you may think of the Midi file format as being antiquated format, best saved for bad cell phone ring tones, the Midi file format can still be of use in some applications, and they are popular in home brewed video games, or for low memory use sounds in presentations.

That does not mean that all Midis are perfect just the way that they are. Let’s say that you found the right track, but it is the wrong type of sound. Should you go onto the next file, and keep looking for the perfect sound, or should you alter what you have to make it perfect?

If that clang of a bell should be the pulling of a violin string, then you will want to consider alteration, since it will generally be much quicker, and you will be able to do it with this free piece of software. Just follow these steps and you will be able to change instruments for your Midi file in Garageband.
