Emax

Ive been wondering about controlling the Emax II functions, such as 
start sample record and stop sample record, and the realtime and 
dynamic processing controls in realtime using a SysEx [System 
Exclusive] fader/knob controller like the Peavey PC1600 and MIDI 
footcontroller ..
(Can all the front panel buttons/commands can be triggered through 
MIDI or at least SysEx ?  Id like to be able to control some of them 
(such as start and stop sampling) with a MIDI pedalboard..
I found SysEx info for Emax1 online but am not sure if it would work 
exactly the same for the Emax II , I dont quite understand it either..
