I was also surprised when I saw Rail's post on gearslutz yesterday.
Steve, check out the manual for a few more details on Accent
http://platinumsamples.com/accent/manuals/Accent%20Ocean%20Way%20Drums%20Manual.pdf I agree this is very inspired by BFD3 with the toontrack midi browser thrown in.
Looks like the plugin supports third party plugins (which in today's day and age of plugin mania is probably a smart move.)
I think I like the slide out concept on the mixer channels.
The manual shows Evil Drums in the library so I expect the PS lineup to be ported over.
Rail hinted that additional content is being worked on in London. Maybe the fx guys are involved behind the scenes, or maybe it is just someone else in London!
I like the look of this. Looks a lot better than the forthcoming SSD5.
