Piano Roll Editor
The piano roll editor allows you to edit the MIDI data for a Virtual Instrument Clip.  Just double click a Virtual Instrument Clip or right click on a Virtual Instrument Clip and select Edit to bring up the Piano Roll Editor.  (The Piano Roll Editor is located on the Sound Details area when a Virtual Instrument Clip is selected.)



Each blue box represents a note.  The note is determined by how it lines up with the vertical piano, hence, the name 'piano roll'.  Click on a piano note to audition how it will sound.

    Snapping In The Piano Roll
    The piano roll has its own snap level which allows you to edit and move notes to exact measure and beat positions.  If you find that you cannot move or resize a note, try turning off the piano roll snap.  Click on the snap button and select a new snap setting.



    Editing Controller Information
    You can edit controller information in the controller area in the lower portion of the piano roll.



    Copy, Cut, Paste And Clipboard Operations
    You can select a group of notes to copy, cut or paste in the expected manner.  You can use the keyboard shortcuts or simply right click on the Piano Roll Editor and select the appropriate operation.  Once you copy or cut some notes or partial notes, the notes reside in the clipboard.  You can paste them at the position of the playback indicator.  Alternatively, you can select notes and paste them to a new clip on track by clicking on a track, positioning the caret in the desired location and then pasting.
