your midi foot pedal should be able to work, based on my limited understanding. you need to set up a program change command from the foot pedal and then map each PC message to the preset you wish.
for example you can hit button 1 on your controller and it will send program change 1 to evenitde. you can use midi map on eventide to respond to PC 1 with present 15 (on the space) or 3.1 on the timefactor etc. the mapping is the critical (and most awesome) feature.
hope that helps.
