prodatum is an EMU Proteus 2000 patch editor for Linux/Mac/Windows. v2 no longer depends on a patched Fl_File_Chooser and links fine with existing FLTK 1.1 or 1.3 installations (for the looks I recommend linking statically with a scheme-patched FLTk version though, patch is in the source tree). If you own one of those old E-Mu synths, give it a try. I'm sure you'll like it. For more information, binaries and source visit http://prodatum.sf.net
