Hi everybody! I have an original Quadrasynth that is in immaculate condition and its been stored in a case all its life but i would like to update it. I thought i read somewhere that it can be converted to a plus model.. but not sure about that. Can someone point me in the right direction to get the most up to date OS? Also anybody know about the firmware Eprom? Can it be changed out if a midi dump update won't get me the latest system? And finally has anyone heard about any other upgrades to get it from Quadrasynth to the plus version? The plus version has extra Rom for more detailed piano so I think there was an update available at one time that had the extra board? If so I'm figuring this isn't easy to come by. But if i can at least update it's OS a little I would be happy. I think then you could use the card slot with custom sample cards? Is there software to do this with? Do i need a special usb to card Interface or could samples be dumped Thru midi to the quadrasynth's card slot? Those are my main questions because that's my main goal in this.Any help is appreciated! Thanks.
