I've purchase it to use as an usb midi controller.
The device is well made and the possibilities seems just fine. However it does not work with my system.
Actually, by reading the different reports it seems great with a line 6 amp but for the use i purchased it, it is just disappointing.
Indeed, when i plug the device in an usb port, it starts on, lights blink and it is recognized by my OS (Mac OS Lion on a Macbook pro Late 2011, the device appears on the report system) but it is not by the Line 6 softwares you have to download from their web site (even the latest versions) so it is not possible to edit the parameters (CCs , Midi channel...) wich makes it useless if you want to use this pedal in order to control Amplitube `Guitar Rig...
It seems to be an ongoing problem for a while, please check their forum :
authorized my computer, uninstalled and reinstalled their softwares (Monkey and FBV Controller), plugged it directly in my computer's usb ports without any other usb device plugged : still the same !
Line 6 support assumed that it is a technical problem and suggested i should return it for a check/change.
I will in fact return despite i kwow it is not a technical problem but a software problem : The pedal works just fine, it is their drivers that do not recognize their own device so it is not possible to update the firmware of the pedal to get it work as a midi controller via usb.
However it might work with a Microsoft OS since i've read some people managed to do it but i'lll suggest anyone to visit Line 6 support website before buying it.
