GarageBand

Garageband is a full-featured computer-recording software program on Mac. The following steps will show you how to use it. First you need to download the Garageband prior to using it. Any version is ok; for example you can download **GarageBand 5.1**, which is a new version. Purchase a digital interface for recording an electric guitar and plugging in a microphone. A midi controller keyboard is also highly recommended.
 * Guide on Using Garageband on Mac**
 * 1. Download Garageband**
 * 2. Get a digital interface**

Open Garageband, choose, "Start a New Project" or "Open Existing Project". Choose software instrument (the keyboard) or real instrument (mic, guitar, or other instrument).
 * 3. Run the Garageband**

A software instrument will be Grand Piano by default. Choose another instrument - synths, strings, horns, drums, etc. The nice thing about using instruments in Garageband is that you can change the sound after the track has been recorded, so you are never locked down to one particular sound.
 * 4. Choose software instrument**


 * 5. Check real instrument**

If you choose real instrument, be sure to click the correct channel-listed in a drop-down menu beneath the instrument effects on the right. Also be sure to turn monitoring on so you can hear the track as it's being recorded. Set the levels for the instrument you're recording. Make sure that the level of the input does not hit the red. EQing and effects can be changed later, but a distorted signal cannot be fixed.
 * 6. Set the instrument levels**

Use loops to set a starting beat. Set the tempo - the default is 120 bpm. Altering this number a little more or less can help your song stand out.
 * 7. Set a starting beat**

Hit the record button and dive in. If it's not perfect, hit delete and try again.
 * 8. Start to record**

Now I guess you can use the Garageband by yourself, can't you?
