Help! Addictive Drums 2 MIDI Note ranges/numbers off compared with Sonar PRV?

I'm tearing out what's left of my hair... 
 
I'm using AD2 as a drum VST. I can go into its Map Window and see which kit pieces are triggered by which MIDI note on a keyboard replica. Every AD2 note is off by two octave ranges compared with Sonar's PRV, where I can see the MIDI notes AD2 is generating in the PRV grid. So, for example, the AD2 keyboard replica is indicating the open snare hit is Midi note 38 and the key on the keyboard is D1. But in the PRV, that note is D3. Same for the kick: AD2 says note 36, key C1. Sonar PRV says C3 (there are no MIDI note numbers in the PRV, just the standard piano keys). 
 
This is mind pretzel. I know there are two Midi conventions, which revolve around what is considered middle C. One convention says C3, the other says it's C4. It may be a USA/European thing? AD2 is a European product. Sonar is an American product. Even allowing for the possibility that they're using the different conventions, that's a difference of only one octave/key range on the keyboard. I've got a difference of two octaves/key ranges between the two keyboards.
 
Any body else have this issue? It's really a PITA because I'm trying to create a custom MIDI map in AD2 for Slate Drums4 and it's not working 100%, and I don't know if this issue is part of the problem.
 
Any suggestions/insight would be greatly appreciated!

Yes, many would use a drum map, here is a KB article about it including AD2 drum maps and templates
 
Still if you want to shift with what notes the MIDI values display in the pane view use Preferences > Customization > Display "Base Octave for Pitches"
 
Right-click the keyboard to change from a keyboard to a different display. It is possible to add additional note names to display.

The try these suggestions Thanks for weighing in.
