[sdiy] BBD a-go-go

[anthony]

So I have 3 MN3006's and 3 MN3007's. I had initially thought
about how I could pepper several projects with a BBD or two.
I like the way these units sound. In their original application they
were quite nice, but simply no fun. And now I'm contemplating
just putting them all into ONE unit. When this idea first occured
to me I thought it was silly. Then I thought well I like silly.
And then I thought hmm wait no this could actually be 
really cool. I suppose someone's already done one better, but
let me know guys if this sounds like a great idea:
Each BBD will have an LFO on their clocks that do whatever
you would want an LFO to do in this application, like
saw, ramp, triangle... And maybe an LFO for an LFO (an
LFO modulating an LFO). So let's say 7 or 8 LFO's.
I'll put an SA575 around it (I don't know how great this
chip is for synth audio though... and it's an SMD so I'd either
have to etch a board for it or cut me up some Kynar...)
And my idea is approaching something more like a synth
module than an effect box - BBD as instrument. It would be
best to have something like a patch bay to run some parallel
and some series - however. CV inputs too... A CV controlled
panner (hey it'll be stereo and then some).

I could do through-zero flanging, negative zero flanging even.
And pitch-shifter? Barbershop quartet!

As fun as this all sounds I reckon it's been done before and like
I said maybe bigger than what I have in mind but what the heck.
Input for tweaks I haven't thought of?
