Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

So I've owned my Digitech 2101 Artist for like 8 years and it has 
3.00.a software.  I also have a Control One.  

I want to get the dual S disc processing upgrade.  How do I go about 
doing that?  Is that a ppc 210 module?  And if I get it, is it easy to 
install?

Also, I am reading about "dumping"?   Does that mean I can create 
stuff on my computer then "dump" it into my 2101?  That sounds friggin 
sweet, but I have no clue how to do that, how to plug my computer into 
my 2101.  Could someone explain it to me or direct me to a website 
that explains it?

Ultimately, I really would like to explore creating more algorhythms, 
and upgrading to the dual S disc, without totally fucking up my 
preamp.  Thanks guys, any help is well appreciated.
