hmmmm...interesting predicament
The Toontrack drum MIDI is formatted for and intended to be used with EZDrummer and SuperiorDrummer.
I'm not saying that it won't work with other virtual instruments or samplers as it has a foundation in GM.
You don't give any specifics about your platform or operating system.
I can only speak for a Mac implementation where EZDrummer or SuperiorDrummer has already been installed:
That location (on a Mac) is:
/Library/Application Support/EZDrummer/MIDI
I can't speak to a Windows installation or any installation where EZDrummer or SuperiorDrummer hasn't been installed first.
