How-to: Use the Scissor Tool
Click on and highlight the scissor tool.
Place the cursor on the part of the sound clip (loop) you would like to cut and click. The Scissor will snap to the arrangement grid unless you hold down the alt-key.
here we went back to the pointer (turning off the scissor tool) and grab the second half of the edit and drag it one 16th note.
In this example we have cut up parts of the clip into 16th note and moved a 16th note apart.
You can also split a clip at the playhead position. Right click and select "Split at playhead".
