I create a new drum map template that defaults to Logic's GM mapping, which is what Logic Drummer uses.
The name of the script is RedirectLogicDrummerToAny and looks like the following:
To use this script, load your 3rd party drum kit and make an alias from Logic Drummer to the 3rd party drum track.
Load this script on the 3rd party drum track, NOT on the Logic Drummer track.
To drive other 3rd party drummers, just map the Logic Drummer drum piece to the 3rd party drum piece.
As an example, I used RedirectLogicDrummerToAny as a template and created the following Drum Maps
RedirectLogicDrummerToAD2 - for Addictive Drums 2
RedirectLogicDrummerToEZD2 - for EZ Drummer 2
RedirectLogicDrummerToSD3 - for Superior Drummer 3
