Dual Passive Switch & Mute Module
This simple but very versatile dual switch is useful for switching between multiple sources. Each switch has two inputs and one output, however being passive, they can also be used in reverse i.e. one input and two outputs.
The switches are also three-way, allowing the module to effectively be used as a dual mute module.
Specific examples of usage include switching between two modulation sources e.g. an LFO or envelope, into the FM input of a VCO, or switching an envelope source between a filter or VCA.
