I'm also going to caution you on trying to get too much jammed into too small a space. Having a pile of two-stages in a smallish module IS DOABLE...but the ergonomics of dealing with the tight patching and controls will eventually wear on you.

Also, there's some larger multi-EG modules that REALLY blow the doors off. The Erogenous Tones Blip/Radar combo is pretty huge...36 hp, in fact. But you get eight EGs, complete chaining capability, plus the Blip allows some wilder functions...for example, envelope sequencing and a truckload of other complex functions that you'd NEVER get in a smaller module. Not in a million, billion years. Nope.

The proper solution isn't ALWAYS the small one.
