ModularGrid Rack

Hi Folks,
This is my first modular setup and I could use some suggestions. My goal for this is an ambient music machine. I think I need a solid function generator and I'm leaning toward a Zadar because it will throw all kinds of shapes by trigger giving me easy note shaping. I also need some effects, but I'm completely lost there. It would be nice to have something that plays with samples like the morphagene, but that's a pretty intimidating unit, and I'm running out of space.
