Just wanted to mention the amazing software editor I just purchased on line for my VL2 as I know there is one for the VL3 & VL3 Extreme. It does all the stuff the TC-Helicon should provide as part of the product

. Menus on the computer for all the effects allowing you to save them and put them in banks. Talks, reads and writes directly to the VL2. The VL3 software is brand new, but if it's as good as the VL2 is a no brainer!
If you do purchase it, be warned that the email can goe to his spam (at least it did for me)when you pay and send the serial number, so if you hear nothing from him, use the contact option on the menu.
He provides demo versions with some features.
