Checking in here to see if there are other Drumcore 4 users.
Are any of you able to see MULTIPLE OUTPUTS and not just STEREO, LEFT and RIGHT?
Sonoma says that the latest version adds support for multiple outputs but I am not seeing them. 
 
Thanks for any feedback as I work with them to sort things out.

I do not have the plug-in but you can check the Details in the VST plug-in properties page to see how many outputs the plug-in reported to SONAR during the last scan.

I only see Stereo, Left, and Right.

At some point I'll report this to Sonoma.
