After your recording is complete, you can perform a number of tasks: 

    

1. First off, listen to your recording.  If you are happy with it then move
   on!

2. If you've just missed a note or two, try opening the Piano Roll and moving
   the out of place notes.  You can easily find your spot by dragging the
   mouse with the right mouse button down across the measure numbers at the 
   top of the Piano Roll View.  As you move the mouse, the notes will play 
   along at the speed you drag the cursor.

3. If you hit all the notes but the timing was sloppy, select the area you
   would like to update, and select Effects > MIDI > Start Times > Quantize
   Note.  Or, just hit the "Q" button at the top right hand side of the 
   application!

4. Quantize will pull your notes closer to the beats.   The top row of 
   controls gives you control over where the imaginary grid lies.  
   For example, if you select an eighth note (and leave Dotted and Tuplet 
   unselected) all the notes in your track will be moved to the closest eighth
   note boundary.  Press the Help button for more detailed explanation of all
   the controls in the dialog.
