Duplicate this full pan delay effect from mod tracker

How do I duplicate this effect, on channel 9,10,11,12 from a song I wrote in modplug tracker back in my youth?

If you don’t know the codes, that’s fine. It is simply playing a C5 panned all the way left and then playing it again, 1/4th note later, panned all the way to the right. Then it does the same thing with D#5, but 1/8th note later.

Should I make one track for the C and one for the D#, and then put a ping pong delay?
Also, I can’t figure out how to make any of the built in delays pan all the way to right or left. It seems to do it at about ±4db instead of the whole thing.
