Thanks, everybody. I took some of the advice in the planning, swapping out the wave folder and the passive mults. As far as substituting the BBD with a digital effects unit… I just like the uncouth sound of BBDs. Some digital effects sound good to me, but my most urgent reason for starting the eurorack was to get some analog effects.
As far as leaving the Subharmonicon in its case goes… this is definitely sound advice. I’m going to mount it in the case for now, however, and probably swap it out for modules when the time comes. My reasoning is pretty simple: I don’t have desk space for the two racks to be placed side by side where I can get to all the controls. Also, the 80 Euros the rack space is costing me is not very significant when you’re buying 3500 euros worth of gear. Putting it in now costs me absolutely nothing except the price of the power cord. Plus, for gigging, I don’t want to carry the two cases!
Edit: oh, ya, and the two Erica Synths Outs were not an oversight. I want four channels out for mixing in my DAW after recording…
