The shortest attack time on the envelator is 1 millisecond 
(1/1000 second). According to psychoacoustic studies, the ear is 
not able to determine envelope times shorter than 1 millisecond. 

Most envelopes have a 5 millisecond minimum attack.

The bandwidth on the current control circuit for the Mixolator is 4 
Megahertz, which is plenty faster than 1 millisecond. There 
should be no problem generating attack times of 1 millisecond.

The Borg is slow due to the Vactrol used which has a 5 
millisecond attack time. The original Buchla circuit used a linear 
current source for the Vactrol LED, this does not work with a 
joystick correctly, and the Borg current source is exponential. But 
that should just make the envelopes shorter yet.
