'I just did it" I had downloaded and installed the AD2 Drum map. Looked at it in step sequencer and felt pleased and posted.

Then I released I had no sound, and when I checked the drum map manager, the Port was set to Quad, not to AD2. I don't think this is right, it surely it should assign the port correctly. Quick fix, in drum map manager, select on of the port assignments and Press CTRL+SHIFT while changing the port when changing the port, to do all 80 odd at once. Save as a new Map

I had done this also, it assigned output to my midi keyboard controller, I changed as above in session, and had sound again, when I reopened project again later, output was assigned to AD2 but had no sound again, re-did the process and still had no sound??? As original poster says Arggggh!, LOL.
Anyway what I really want is names assigned in PRV not drum "pain" LOL, despite its possible virtues.
I think another way to do this also may be in AD2 where you can reassign kit piece to different keys, so say the same as those used by the General Midi Drums instrument, (which you can assign to PRV keys), in any case, its matter of taking the time to do it.

Open AD2, click on the question mark in the top panel, choose map window. Go to Map preset in the top right hand corner and choose GM from the menu below.
 
Never tried it.

Word of warning, using GM simplifies a lot of the hit nuances.

Gee it would be nice to be able to do all these tests, so far the inane crap of xln online loader forces a FULL update to ALL products, whether you want to or not, or by deselecting components it uninstalls them, no option to "leave them alone, I just want to update AD1 to AD2", and there's no bloody answer as to how to achieve it without a full bloody install of everything, BLOODY incompetent and useless!

You need to do a custom install.
