[sdiy] Multiplier vs VCA?

[mirwin at qouest.net]

Hello List,
It is possible to "bend" the control response of the dB/V VCA chips to 
implement linear response VCA's... for a simple method to turn a single 
Analog Devices SSM2164  VCA chip into a Dual High Quality Linear VCA, 
see the following article (be careful with the word-wrap when clicking 
on the URL):

Anyone know if this circuit technique is being used in any currently 
available synthesizer modules? (it is being used by Modcan)
