The "VCA" mode of either Borg makes it a 1-pole filter; 6db/oct.  

The basic sound of the Borg2 and the Boogie is quite separate and
unique.  The Boogie is a ladder design - it has a 'Moogish" timbre. 
The Borg 2 is a 12db/oct state variable.  

The lowpass gate isn't just for pinging pulses.  In the older Buchla
200 systems, a lowpass gate could be used in any situation that a VCA
in any other system could be utilized.  

In fact, the Borg 1's decay is too slow for many applications typical
of VCA performance.  The Buchla's 292 lowpass gate was snappy and
closed off completely, but its setbacks were the fact that it had a
quasi exponential cv response, resulting in it being off for a large
portion of its cv range, and that Buchla audio systems were only 1v
peak to peak rather than the 10v peak to peak of the Wiard and other
systems.

The Borg2's performance is really stunning as a lowpass gate - much
faster than the Borg 1, it performs fantastically in just about every
instance.  The attack response is so fast that one can really tune the
woody "chunk" at the front of the transient.  

I contend that "the Wiard Sound" is the sound of two Wiard filters in
the patch.  The Boogie and Borg 2 make a great match for Filter/vca.
