I really want the modulation matrix of the 4K and it's extensive filtering and layering options. I guess I might have to try one to really find out what it's capable of, but I have some doubts about it. Maybe it's better in other features though.
Anyone here have a link to the current Ren manual? 
You probably won't find an updated manual because of the constant updating here recently.
I would recommend you take a look at the youtube videos for 1.7-1.8 from Sounds for Samplers and Hellfire to get an idea of if the Akai software current version suits your needs. As for Filters in the Program Edit window I would say it's based off the MPC 4000 with the editing capability of layering sounds and applying the filters.
