I will also ask XLN and Drumagog about this but wanted to check here first.
 
When using (new 64 bit version) Drumagog's plug-in hosting feature it sees Addictive Drums and a 32 bit vst and won't allow it to load. I have it pointing to the correct folder on my system and the .dll file that resides there is for the 64 bit version of Addictive Drums (I've checked and double checked this). I know that there are 32 bit versions of Addictive Drums on my system as well, in both vst and RTAS form but technically Drumagog and SONAR can't see them as I don't have those folders selected for either program. Any thoughts before I email the other vendors would be appreciated.
 

I've never drumagog'd Addictive. I'll give it a try and report back.

I have 32bit as well as 64bit AD and Drumagog installed.
 
I only scan 32bit plugs in 32bit SONAR c:\Program Files (x86)\vstplugins as well as <SONAR32bit>\vatsplugins
I only scan 64bit plugs in 64bit SONAR c:\Program Files\vstplugins as well as <SONAR64bit>\vatsplugins
 
I opened a fresh project 64bit project.
Insert Synth -> Addictive.
Grabbed a beat from the browser.
Played the beat.
Inserted Drumagog on kick track
Loaded fine
Selected replacement kick
played new kick as expected.
 
 
 

I can do that as well, but did you use the plug-in hosting feature where you load Addictive Drums inside of Drumagog? You have to have Drumagog 5.2 Platinum to do that. and that is where my issue is.
