Pencil tool: This let’s you individually draw notes in the piano roll.
Have a play around with creating some basic chords or melodies within the piano roll, and experiment with these tools to manipulate your sequences. I won’t go into too much detail on each icon here, as they are fairly self explanatory, but hovering over each one will tell you about the function of the button. These are your editing tools, and can be used to precisely edit, slice, lengthen and select your notes. Along the top bar of the piano roll window, you’ll notice several icons.
