Works for me. The less time I have to spend scrolling and actually setting a level and listening the better. This is why I prefer to have the rigs on the same bank or in succession. On the Digitech GSP midi controllers you could call patch/rig A1 with pedal 5 and call patch t3 with pedal 4 for example.
I am using the Roland GFC 50 to control the unit.
Are there any controllers on the market that work lick the Digitech?
