If you sweep the resonance with an envelope, you might be able to
get a good snap at the beginning of a bass sound. Apart from that, 
I can't see great use for it. 

But I understand that this is pretty typical for how resonance 
works by default: it's supposed to emphasize frequencies around the
cutoff, after all. In some designs, when you emphasize higher 
frequencies, the bass decreases noticeably, and the Moog is one of
those designs. I guess other filters like the Roland ones, and the 
OBX, work around this design issue somehow, as the decrease is less
noticeable.

Basically, when you program bass using Moog filters, you tend to 
keep bass at a minimum. On the A6, you could compensate by using
either the direct sine outputs or the 12dB output.
