Wayne Stahnke's Live Performance software collection was created by a unique process of scanning master piano rolls. By using a CCD scanner it produces a computerized "picture" of each entire master roll. The next step involves a complex program which analyzes the timing on the roll, and reproduces the exact timing grid that was used to make the original master roll. The result is a file that exactly copies the original master roll, and eliminates the errors caused by roll duplication. From there, a series of steps converts the information to a Disklavier file.
