Hallo..i have some questions about the flextone iii xl...i have this amp and its absolutelly good..but also i have the fcb1010 midi foot controller and i dont know how to use the amp with this...

Flextone has 4 chanels so i can save four different sound that i like..also has 36 presets as it says..BUT when i use the pedalboard i press the 1 or 2 or 3 or 4th pedal on the FCB1010 and the sound changes 1-2-3-4th respectively at the chanels that i saved..when i press the 5th or the 6th or some higher pedal numbers then the sound goes to the presets...How can i save the sound that i want in the pedal tha i want???can i make more than 4 sounds and save them then use it from the peadlbard??

HELPPPP!!!!THANKS!!!!!!!!
