Getting Started in GarageBand

The keyboard will automatically be recognized by GarageBand as soon as it is plugged in.  The GarageBand controls are described below:

Track Selection - The Track Down/Up buttons select the previous or next track in your song, within the selected bank of 8 tracks.

Controlling Track Volumes - The 8 faders (49 & 61 key models) control the Volume of Tracks 1-8 respectively.  If there are more than 8 tracks in your song, then you can use the Track Down/Up Buttons with Shift held down to select the previous or next bank of 8 tracks.

Alternatively, the Volume of the selected track is also controlled by encoder 1 (25, 49, & 61 key models).

Mute/Solo Tracks - The 8 buttons below the faders (49 & 61 key models) mute tracks 1-8 by default.  Holding down Button 9 will allow you to Solo tracks with these buttons. 

Alternatively, the 'Mute' button will mute the selected track.  Hold Shift down and press mute to solo.

Master Volume - Fader 9 will control the Master Volume of GarageBand.

Parameters in the selected Track - The 8 encoders map to various parameters in the selected track as follows:

Encoder 1 = Volume
Encoder 2 = Pan
Encoder 3 = Send 1 (most commonly “Echo”)
Encoder 4 = Send 2 (most commonly “reverb”)
Encoder 5 = Low EQ Freq
Encoder 6 = Low EQ Gain
Encoder 7 = Hi EQ Freq
Encoder 8 = Hi EQ Gain

To see all of the parameters within the selected track, expand ‘details’ in the ‘Track info’ pane on the right-hand side of the GarageBand window.  To hear the effects of the knobs, you need to enable “Visual EQ” and the 2 sends effects below (most commonly Echo and reverb).
