Recording in GarageBand on a Mac with MiC and JAM

In this tutorial we will show you how to connect and use both MiC and JAM at the same time in GarageBand.  You will need to be running OS 10.6.8 or higher on your Mac and GarageBand '11.  

  1.  Connect both MiC and JAM to the USB ports on your Mac.
  2.  Open the utilities folder  (found in the Applications folder on your Mac),
  3.  Locate Audio MIDI Setup and open it. You will see both JAM and MiC listed.
  4.  Click on the add button to create a new aggregate device
  5. Click on MiC and then JAM.  You will see that MiC is listed first, making it input 1 and JAM second making it input 2

  7. Open GarageBand with a Guitar Track
  8. Click on the plus button at the bottom of the screen to create a new track.Choose “Real Instrument”
  9. Click on GarageBand Preferences, and then Audio MIDI.  For “Audio Input” choose “Aggregate Device”.  Make sure “Audio Output” is set to “Built-in Output”
  10. To record more than one track at a time in GarageBand, click on “Track” “Enable Multitrack Recording”
  11. Select the “Guitar Track” and click on the Amp and select "Edit".  You will see that input source is set to Mono 1
  12. Since input 1 of our Aggregate device is MiC, set the to set it to Mono 2 (which is JAM)
  13. Set “Monitor” to ON
  14. Now Click on the Vocal track
  15. You will see that the Input source is already set to Mono 1. So just set “Monitor” to “ON”
