MultiPads are type 1 midi files where each track corresponds to one pad sequence. Chord Follow and Loop are defined by two text events at the beginning of the midi(Look in File/Info in Cakewalk) as follows CM1111 defines the follow where 1 is on and 0 is off and RP1111 defines the loop function.

I created a midi template file that includes these events and other stuff for making templates from scratch. Its at:http://www.svpworld.com/2000world.htm
