Like the DX7?

Try NI FM7 VSTi. Patch compatibility, plus analog filters (modeled, anyway) and a host of other additions. Far less aliasing and noise (unless you want it ) and some amazing presets. Cheap, too...

BTW, I have an E! Grey Matter DX7 as well. It was worth it for the massive patch storage alone, never mind the improvement in MIDI capabilities. Wore my first, original DX7 out during the eighties... got one within weeks of it's launch when they were harder than hen's teeth to find, in a Mom and Pop store in Youngstown Ohio who had no idea what they had. While everyone else was paying OVER list for theirs, I got a nice discount!

The current one sits in the case, waiting for me to open my museum...!
