I have commented before about all keyboard manufactures providing a HOW TO TUTORIALS with new models.
One of the main problems with keyboard buyers changing or adding a second brand is not excepting having to learn a new OS system. Tutorials such as this are an excellent way to overcome this.
Well done KORG for providing the Video Tutorial on the PA800. All manufactures should be providing this sort of product tutorial. Possibly also on DVD for none PC uses. PA800 Video downloadable from www.korgpa.com
