I think what you want is the loop function.
go to seq and push over untill you see:
"overwrite" then push up untill you see:
"Loop 000-999" (or something like that)
change the measure numbers to the ones that you want played over. This will affect the whole sequencer (all 16 tracks). Everything, even controllers will repeat. You can mute and un-mute any sounds you want.
If that isn't what you want you can copy and paste the group of 4 measures lets say from 001-004 to 005-008 and 009-012, ect. The copy function is in the seq. edit mode. (go into sequencer and push the edit button)
I hope this helps,
