Thanks to both of you. I will check out the D50 and D20 definitions. I also heard that the D-110 matches up pretty well to the D5 definitions. If I need to define a file from scratch I will use Dave's FAQ link.
D K, I agree the D5's sounds are not very good, but there is one patch I used for a song I sequenced a long time ago (in the early- to-mid 90's) that decided to work on again. One particular D5 patch I used in that sequence fit well and I haven't found a good substitute in my soft synths.
