I'm not quite sure if I understand which effect the OP is referring to, but in general I feel AD2 has the best hihat response of all the drumplers (with my Roland TD-4K pedal). The one I struggle with is BFD3.

Hi all. Would love to set up my Roland TDK 11kv pads to trigger corresponding AD2 kit pieces in Sonar Professional via MIDI.
 
In searching the boards, I've learned the answer to my first question here, that being "Can the Roland pads be mapped to trigger AD2 sounds?" I see from the discussion that the answer is apparently yes, though there seems to be a hihat issue. To get started, can someone point me to a resource that explains how to map the roland to AD2. 
 
Thanks!

Doh! Disregard my post. I see that AD2 has built in map for Roland kits. Awesome!

That mapping never worked for my hi hat foot pedal. I switched to BFD3 and everything worked like a charm from the first attempt.

I'm now waiting for the next version of Addictive Drums with the hope they add some improvements in.

Got the mapping figured out and the hihat seems to be responding okay. Dealing with a latency issue now. Play to Sonar's metronome and the drum sounds lag the pad strikes so everything is out of synch.

I have a Roland TD30.  In my experience, the built-in map in Addictive Drums for Roland V-Drums is not quite correct, but mostly so.
 
I had to tweak the map to match the V-Drums.  Using this map, AD uses MIDI CC #4 as the HiHat control signal which is what is transmitted by the V-Drums; this information is used by AD to determine how open the hats are and thus what samples to play to represent the HiHats being that open/closed.
 
I'll try to find out what tweaks I needed to make from the default V-Drum map in AD and if successful I'll update this thread.
 
[edit] Just saw the note about latency, I am experiencing something similar; I get less latency monitoring the audio from the V-Drums (i.e. through the DAW!) compared to sending MIDI from the V-Drums and using that to control AD.  Which is plain daft.  I did have an idea to turn local OFF inside the V-Drums to see if that made any difference to the latency but haven't yet tried that.
