You have to replace the linear current source of the A-132-1 by an exponential type (one operational amplifier, two transistors and a couple of resistors and capacitors). In any case electronic experience is necessary. Or you look at the A-132-3 which has two VCAs that can be switched to linear or exponential. Best wishes Dieter Doepfer
