Making LED and LDR Optocouplers (the Vactrol thing)

Making DIY Vactrol style optocoupler using LED, LDR, shrink tube, plastic and paper. This kind of optocoupler can be used on many circuits that require a voltage/current controlled resistor, such as VCA, audio compressors, limiters, expanders, VCO, voltage controlled LFO, phaser, VCF, etc. By varying the current on the LED (Light-Emitting Diode) in order to control its brightness, we also change the resistance of the LDR (Light Dependent Resistor) receiving the LED light. Although not suitable for applications requiring fast response to control transients (sudden changes on control signal) this kind of optocoupler can substitute the use of OTA (Operational Transconductance Amplifiers) for a fraction of the cost.

Hola... digo yo... para controlar un vca o un filtro, si uno quiere un envolvente con ataque bien rapido, como para un sonido de percusion o algo asi... el vactrol no seria un poco lento..???
Hay alguna forma de hacerlo mas rapido..??? Que es lo mas lento, la celula o el led??? Sin embargo se utiliza el sistema optoelectronico para transmision de datos a altisima velocidad...
Yo probe varias veces los vactrol y me resultaron lentos... y mucha gente en los foros dice lo mismo...
Cual seria la mejor forma de hacer un optoacoplador lo mas rapido posible.?
De que depende? Del circuito, del led, de la celula?
Gracias...
