I have no been around in a long time.

Hi Everyone
I got my Mint condition DX7s out of the fight case and fell in love with it again. I cant seem to find a the Grand piano and B3 patches that I got off of  a Demo at Guitar center many moons ago. I would like to get some new cool patches. In the flight case was a song list of Elvis songs I did in Vegas back in the day . Ben Weisman, the man who wrote more songs recorded by Elvis than any other songwriter in history also played on this Dx7s keyboard.  Can I download or , how do I get some new sounds into this old Gem ?Thanks " Chicago Fred"
