would love to hear feedback on this desired lay out. I'm new to all of this and I am going off of some racks that others have suggested. Looking for something that can drone & create rich textures.

If you like autonomous atmospheric drones then I can recommend the Titan Capsule Modules by Eowave (ModularGrid Rack). These seven modules constitute a complete, traditional (i.e. twin VCO, VCF, VCA, ADSR, dual LFO and Mixer) synthesizer voice specially designed to create atmospherics. These modules are very reasonably priced and take up only 40HU of rack space; I have a set in my own modular system.
