Dave Smith Instruments SYNTHESIZERS

Hello all,

Yesterday I fucked up a fantastic sequence which made me feel so good. 
Listen hours and nothing boring, just very good!

But after some tweaking I did a save operation and now I lost it.

What is the easiest and quickest way to reinstall the original 
patches? Is there a tutorial or something about this proces?

I do know it has to be done bye a sysex file, but which programm and 
what else do I have to know in order to install correctley?

Thanks.

TC
