I just purchased an es7 secondhand. Unfortunatleyan the seller didn't have the factory disk(s) that came with it. I would like to get my hands on one so that I can upload the infamous "powergrand" patch on my board. Can some help me out by either letting me get a copy of the sound library disk or point me into the direction of obtaining one. I called yamaha support. The guy stated 3 disks were shipped with each board, but he doesn't know which is which. I didn't want to buy all of them or the wrong one. Thanks LGM family.
