Right clicking any playable in the pane will cause a context menu to appear on the layable. It has six menu options:
Clicking on the "Play Selected" item will cause the playline and the midiplayer to play from the beginning of the first selected playable to the end of the last selected playable. It will play exactly the notes that were selected when the context menu appeared.
Clicking on the "Change Volume" item will cause a dialog with a text field to appear. Entering a number from 0-127 and clicking "OK" will cause the volume of the selected notes to change to the appropriate volume and the brightness of the color to change proportionally.
Clicking on the "Change Instrument" item will cause a dialog with a drop-down menu to appear. Selecting the desired instrument will cause all the selected notes to have the new instrument's sound and color.
The same as the "Group" main menu item. Selecting this item groups the selected playables together into a gesture. This item is disabled if only one playable is selected.
The same as the "Ungroup" main menu item. Selecting this item ungroups any selected gestures. This item is disabled if there are no selected gestures.
The same as the "Delete" main menu item. Selecting this item deletes the selected playables.
The names of the appropriate notes now appear in grey at the leftmost edge of the scrollpane and every 1000 pixels. There are grey vertical lines every 50 pixels to represent eighth notes.
Under edit there is a "Quantize" menu item which when chosen will snap the selected playables to the beginnings of the eighth note lines.
