You have to split the sequence into 2 "sections" (not to be confused with seq64's Sections).
In Anvil Studio's Event List tab, Insert an event into the "Song Properties" Event List. Choose the time where you want the loop (for example 03:01:000), check the "Include Meta events", select an event called "Marker" and type "Section 1" in the text field.
This tells seq64 to separate the sequence into Sections 0 (intro) and 1 (loop).
Then in seq64 on the "Seq" section (should be 1st) you should see 2 groups of "Absolute Chn Ptr" commands and in the end a "Branch Abs Always" command. Put the address of the first Absolute Chn Ptr of the second group into the value of the Branch command. Then it should loop from where you selected.
