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

Hi,
I think I'm the newest member in this group. I own a Digitech Valve 
Fx, and I'm about to buy a 2101. So here are some questions:

1- Is it possible to send my patches from the valve fx to the 
computer, then to the 2101?
2- Is there any program like RPEDIT that I can use to edit the 
patches (not just the algoritms) from the computer and then copy it 
to the 2101?
3- Does version 1.00.00 comes with the intelligent pitch shifter?
4- How I upgrade the software version? Do I have to take it to a 
dealer or can I do it myself?
