I use a Behringer FCB1010, which has two buily-in expression pedals. I typically assign the first one to control my guitar pre-amp, and the second one to control my H7600. Via MIDI programming through a PC Editor, it is possible to assign each of the 10 buttons of the 1010 to instruct the expression pedal to control up to 10 MIDI parameters on the H7600. Now, by design, VSigfile and the 7600, and I assume the 8000, can display up to 8 MIDI parameters per display page, so if you need more than that, you can setup the 1010 via MIDI to switch to other menu pages, via Orville MIDI controls that Italo made available on another thread. So I setup buttons 9 & 10 on my 1010 to go up and down menu pages, and 1-8 to control up to 8 MIDI parameters on the 7600. In a nutshell, I can completely control every 7600 patch and its parameters via the foot controller. I'm sure other MIDI floor boards can do that as well, but I found that many, such as the Roland, does not come with a PC Editor. The latter makes MIDI programming REALLY easier.
