Hello All,
           Just got my 3 modules a few days ago (Envelator, 
Mixolator, and Borg), and they are great. However, I don't notice 
much of a sonic difference between the Borg with "peak" set to 
minimum, or with it set to "VCA". "Type" is set to LP, per the 
manual. 
Am I missing something? 

Thanks,

Rob

No, it's working correctly. VCA mode on the Borg removes the feedback  
(resonance) circuit for a 6db rolloff.

With the control engaged but set to minimum there is nearly no  
feedback, so the sound is very similar.

If you listen very close, you'll notice the VCA mode is slightly  
brighter and more "open sounding."

This feature wasn't on the 1.0 Borgs.

Somene please correct me if I worded any of the above wrong.

The VCA mode replicates the "dual" mode of the Buchla Low Pass Gate,
which is part of Grant's inspiration for the Borg.  When used as a VCA
in a percussive patch, it exhibits the characteristic "snap" which, up
to the recent appearance of "low pass" gate circuits around, was an
important and unique characteristic of Buchla systems.

VCA stands for "Voltage Controlled Amplitude" so the switch 
removes the majority of frequency modifying effects, and affects 
primarily amplitude.

There is still a very soft frequency falloff that is said to mimic the 
effect of air humidy damping on high frequency sound 
components as they receed. It's most useful for film sound track 
work when you want to simulate a sound source approaching (or 
receeding) from a distance.

The Borg circuitry is very low parts count and extremely low noise 
floor. A 24 bit A/D converter is noisier than a Borg filter, so you 
can easily run the whole mix through the Borg to use as a 
mastering filter or tone control. The front panel Freq control is 
deliberately limited to 10 kHz (for playablity) when fully open. To 
open the filter all the way to 25 kHz, add some voltage in through 
a Key Follow or Modulation jack.

Also, the noise floor is so low, you can use it inline with a guitar 
to make a really super "Wah" effect with variable mode, peaking 
and extended range.
