I don’t think you should see the Doepfer BBD as a normal BBD delay. If I’m right there is no filter for the BBD clock noise, which is an awfully harsh sound that lowers in frequency as you lengthen the delay time. So if you’re using it as a normal delay, make sure to add an extra lowpass filter just for the feedback path of the delay. It’s an amazing creative module for time-based fx and karplus strong synthesis, though - and if you decide to get the extra filter, it’ll be an extremely flexible delay!

I heard something about this, but ... we'll see how it goes I guess. I'm more interested in experimental and interesting sounds than standard FX, so it should be fine. I've actually tried to sort of order more than I may need in some respects while I have the opportunity to do so, figuring some will be traded or sold off depending on what kind of workflow I find myself falling into and which units I enjoy the character of the most. Polished certainly isn't always my pref. I had a Korg SQ-1 sequencer, and a Rucci 16 step sequencer, and recently had to trade one off ... I opted to part with the SQ-1. It does way more than the Rucci, which is purely CV and a little wonky, but I just enjoy working with the Rucci, it does what I want and has character and charm.

Apart from that, the usual stuff people forget: attenuators, mixers, VCAs. There are quite a few sound sources in this rack, you’ll need ways to control them. I have only 3 monophonic sources in my current rack, and about 10 VCAs, 4 mixers and 3 attenuators. But if you start with purchasing the voice that interests you the most, you’ll find out on the way! Just don’t buy too quick and take the time to get to know your modules :)

Hmm, thanks for the tip. Those are startling numbers to be sure. I've heard people tend to underestimate the VCAs they need, but I thought between the Quad VCA, ADDAC unit, and the Mixer I might actually be overdoing it. I might have to reprioritize a bit.
