[sdiy] I'd like to design a usb or card i/f for patch storeage

[Bob Weigel]

Maybe someone has already done this.... if not...Is anyone up to speed 
on the latest chips?  I think I'll try to build something that will plug 
into the card slots on some different things.  I have working cards for 
MKS30 but I thought it would be swell if 1) batteries were out of the 
picture 2) you could actually back up the data to a pc   Rather than 
losing it all when battery goes down.  Since 1G is so cheap now I figure 
creating a card emulator that can both take data from the internal 
memory in normal fashion AND read from any patch bank stored on the card 
when commanded to do so by a select encoder and display to show which 
bank is being pointed to...then you could have unlimited memory of 
course funcitonally and be able to take the data to a pc and store it.
