Frickin' excellent! All of the interconnectivity between the kb37 rig and this stack should keep you busy for some time. I take it you've got a proper outboard mixer, or at least a digital interface that has enough inputs to separate all of this onto their respective tracks? The DFAM is something I've certainly considered...not for drums, however, but more for its 2 x 8 step sequencer and to separate out the various submodules in it via the patchpanel to drop into other signal paths. Ultimately, I think that might be its best use, and for the price, that's a lot of module functions!
