The Claw Machine tool removes notes, adds notes and/or shifts the timing of notes to create interesting new rhythms. Claw is a great tool for working on starting scores with regular rhythms, although experimentation will be rewarded.
NOTES: The Piano roll Claw machine works very effectively with drum/melody loops sliced in Slicex to create new rhythms. If you need to perform the Claw process on audio files then use the Claw machine tool in Edison.
The Claw Machine works by defining a Period, then cutting the period into a number of slices set by the Trash every setting. The slices are either removed ('clawed') or used to redefine note boundaries. A good way to learn how claw operates is to place a regular - whole, 1/2, 1/4 and 1/16th note patterns in the Piano roll and process it with various claw options.
