Frap Tools 411 Quadruple Linear VCA, Mixer, Multiple Module.
The 411 is a quadruple linear VCA, mixer, and multiple for audio and CV.
It consists of four linear VCAs with semi-normalled inputs and CV inputs, −6 dB attenuation switches, a mixed output, and an unpatched output.
The 411’s architecture allows to use it in many ways, for example:
processing four signals independently;
modulating one signal with four CVS and sending it to four different destinations;
mixing up to four signals and modulating them with the same CV;
mixing two audio signals and modulating them with a modulated CV…
Key Features:
Four DC-coupled linear VCAs
The 411 has four linear VCAs perfect for modulating audio signals and control voltages.
Semi-normalled signal and control inputs
The signal inputs and the CV inputs have cascaded semi-normalled connections. Every signal patched to an input also feeds the following ones, allowing for infinite combinations of sources and modulations.
Mixed Outputs
The 411 features an All output and an Unpatched output, just like the popular 321 module. The All output mixes the four sections, while the Unpatched only those whose local output is not going anywhere.
-6 dB Switches
The switches halve the CV input, allowing the 411 to work with both 0-5 and 0-10 voltages.
Open by Default
The VCAs are designed so that they stay open even if nothing is patched to the inputs.
