Dear Friends: I have a bunch of old midi gear and need to replace the batteries and, more importantly, find downloads of the ram programs (patches). The gear: Korg, Kurzweil, Roland, Yamaha, Emu, etc. You get the picture. I've done some on-line research, but haven't been too successful in finding downloads of the programs. I have a recollection of replacing the programs via sysex in the old days, but I still need the original programs. Also, I'm not certain where I can locate the batteries. Any help would be appreciated. Thanks.
