10.2. Mute Some Tracks

If GarageBand announces that "Some parts were not played ," at least you should be the one determining which parts. As you work, you can mute the tracks whose playback you consider expendable for the moment. (Click each track and press the letter M key, or click the little speaker icon in the track header.)

Any track that you silence like this is one more task crossed off the Mac's real-time To Do list. By selectively muting and unmuting tracks, you should be able to get your piece mostly ready. Afterwards, you can either export the thing, convert some Software Instrument tracks to Real Instruments, or even bounce the whole thing into iTunes and back. Both of these radical tactics are described later in this chapter.
