I have two Doepfer A-140s and a Cwejman ADSR-VC2. In real-world use, both envelopes are capable of settings that exceed my requirements of a 'snappy response'. Anything measured in the microsecond range should be sufficient. They're snappy beyond the point of diminishing returns. A faster response isn't going to be musically useful, IMO. The control signal itself is one factor, the device that being controlled by the signal is another. Take, for example, a VCA. It feels like there are some inherent slew characteristics that factor into the overall experience. I like the Cwejman VCA-2P for response and the quiet operation/noise floor/dynamic range. The log/exp mode switch on the ADSR-VC2 also changes matters dramatically. When paired with the lin/log switches on the VCA-2P, this produces four audible variations of contour characteristics and they're all useful. The ADSR-VC2 has CV inputs for each stage, but the A-140 has none. The Doepfer A-141, which has VC inputs, seems to have a sluggish response in comparison to the 140. The 141 has built-in VC input attenuators, which the ADSR-VC2 lacks. This can be addressed with an external attenuator like the Plan B model 36 ELF Leveler, which is inexpensive and consumes only 4HP. - matthew http://stretta.com
