    A-101-6 is a new filter module that uses so-called opto FETs to control the filter frequency.

    Opto FETs are very similar to Vactrols but use light depending field effect transistors (FETs) instead of light depending resistors (LDRs).

    A opto FET is a combination of a light depending FET and a LED (light emitting diode) both put into a small light-proof case.

    The advantage compared to vactrols is the much faster response of opto FETs compared to LDRs. This allows much faster attack/decay times and even FM effects.

    The disadvantage compared to vactrols is that the FET behaves as a normal Ohm resistor only for small levels. With higher levels the FET begins to distort. Apart from this the notes mentioned on the Vactrol Basics page are valid.
