hello all . i just got my kemper. when i bought my mastermind gt 22 it came with 2 rjm expression pedals. i am a total noob, so i am trying to figure out how to set this up. Do i plug 2 cables from 1st pedal to ports 1 and 2 on the back of the mastermind and the second to 3 and four? i want to control wah, filter and volume as well as pitch. any help would be amazing.
