Vactrol

Vactrol Grundlagen. NOTE: Dot on case marks the cathode (-) lead of the LED. These are the same vactrols that.

A “ vactrol ” is a combination of a light dependent resistor (LDR) and light source both enclosed in into a small, light-proof case. The vactrol , also known as resistive opto-isolator (RO), or photoresistive opto- isolator in its simplest form is an analogue optoisolator or . In early designs .

They are not stocked because nobody is using them in large quantities. The kind of designs that can be (kind of) achieved with vactrols can also be done with op . Voltage Controlled Amplifiers (or VCAs) are a common component in modular synthesizers. A few of the vactrols had broken LED leads.

I carefully cut away the surrounding potting material to salvage the LDRs. I built a dual vactrol , giving me simultaneous voltage-control over two potentiometers. Ofcourse I could go and just order a eurorack VCA module, but making one myself would be way more fun. And reading about vactrols and how .

MUTANT VACTROL VCF for Eurorack synthesizers - VC vactrol based multimode filter. Thanks a lot to Scott for kindly . Far more mutated than I had expected. We use it as the . The name is drawn from the two main components that define the function and characteristics of the module. One is the vactrol which is a light controlled resistor , .
