in Amiga MODs. Amiga computers had four audio channels - they panned 1 and 4 to the left, 100%, and 2 and 3 to the right. This is rather unpleasant to listen to on heaphones, but some afficionados still like to recreate it. Values of between 10 and 20 offer just a bit of separation, while 0 gives none and 100 gives Amiga-style hardpanning Click/drag the mouse up and down.
