Editing Software Instruments
GarageBand has a great collection of Software Instruments, but there is going to come a time when you want to tweak an instrument to make it sound just right, or you might even want to perform massive surgery on an instrument to give it a sound all your own. We will go into depth about creating your instruments in Chapter 8, "Making Your Own Software and Real Instruments." But for now we'll show you how to alter a Software Instrument and save it as part of your song.
Software Instrument Settings
If you open the Track Info window, you will notice a triangle marked Details... in the lower-left corner of the window. If you click that triangle, suddenly the Track Info window expands and you can find all the settings which make each Software Instrument unique. Take a look at Figure 3.11.
The Two Parts of a Software Instrument: Generators and Effects
There are basically two parts that make up a Software Instrument: a generator, which creates the instrument's sound, and effects, which alter the instrument's sound.
The main difference between a Software Instrument and a Real Instrument in GarageBand is whether or not the instrument uses a generator to make sound.
If you are feeling brave, you can adjust the settings inside the Track Info window for the current instrument and then close the Track Info window, and your changes will be applied to the instrument and be saved along with your current song when you save your song.
However, if you change the track's instrument before saving your song, your changes will be lost.

Saving an Instrument
If you tweak the settings in your current instrument and then attempt to change the instrument for the current track, you will get a dialog asking you if you want to save the file before switching to a new one. You can select Don't Save, which simply forgets the tweaks that you made and loads the new instrument. If you select Save, you are presented with a Save As dialog, which allows you to save your tweaked instrument under a name of your own invention.
You can also click the Save Instrument button in the lower-right corner of the Track Info window and you will be presented with the same Save As dialog.
Again, we will go much more into depth with creating your own Software Instruments in Chapter 8.
