As you know, VC-1 can only send whole banks as SysEx dumps, not single patches. I created a MIDI file with a data request SysEx message that "asks" VC-1 to send a temporary patch. With this SMF, you can store patches in MIDI files, given that you have a hardware or software sequencer to connect to your V-Synth.
Get the SMF at: http://artemiolabs.com/downloads/sysex/roland-d50/
Hope you'll find this one helpful. I myself tested it and I will use it to share my own patches with you.
