Thanks Kevin for the soundfont download link. I converted it to a sfz file and loaded it into ARIA.
John,if you can convert sf2 files, the following link may be of use. It's to the DX7 Bank 1 patches in sf2 format. I'm in the process of converting them all with the sfZed editor.
http://soundfonts.homemusician.net/collections_soundfonts/dx7.html Alos here is the link to the sfZed in case anyone is interested.
http://audio.clockbeat.com/sfZed.html I don't get into the editing side as it's rather new to me,(read don't know what I'm doing!) I just do a straight conversion to sfz format. You could load them into any sfz player and they should work.
I still like the old gear even though I work "in the box" these days. My DX7 is under the bed waiting repairs. I'll never sell it or the D-50
Mac's suggestion to look into the GM Electric Piano was a good one. I like the EP's especially the Legend and the FM pianos in the GS format of VSC Dxi as well.
I don't think anything can match the real thing but at least it's something.
