Inside Sweep lives a pesky little virtual stylus called Scrubby who enjoys mixing around in your files. Scrubby can be quite a lot of fun to play with, because you can drag him around any digital audio file just like dragging the stylus around on a vinyl record.
For editing purposes, Scrubby can give you a very clear idea of exactly what is in the file you are editing. You can drag him around your cut points to find exactly where to make an edit, just like you would have slowly turned the reels on a tape machine in the old days. You can also place him in a file while an effect is being rendered to zone in on the changes in real time.
