[sdiy] What would be THE best, most versatile VCF available on DIY community ?

[Jean-Pierre Desrochers]

I know this is a question of personnal tastes
but some winner designs are all around so...

What would be THE best, most versatile VCF
available on DIY community ?
I'm talking about lo-pass, band-pass, hi-pass selectable
VCF with also 12db or 24db/oct selectable choice..
I'm starting to grab some ideas about a very good VCF.
The format doesn't matter since I'll finally retrofit it
to dotcom format.
So far the design that would please me would
be made of a motherboard designed from the lo-pass
Moog transistors ladder idea but ready (with pins or connectors) 
to be emptied and 'accept' ARP type VCF daughter boards on top of it
with the needed 'frontend' driver/summers ICs  space
to completely change its design from a VCF module to another one.
Multiple VCF types with one motherboard and many VCF daughterboards
like the ARP 4012, 4035, 4072, 4075..(or other companies small PCB designs)
Here, I'd still have no band-pass, hi-pass type but
as I said I'm just starting of thinking of the possibilities..
Thanks.
