MRG Synthesizer - VCA
It's an extremely flexible module and can be used in a variety of ways.
Both VCAs can be controlled by a CV entry, modulated by control knob.
VCA1 also has an initial gain control (B1), that offsets the CV input by a constant value.
This allows VCA1 to be left always open, with the initial gain controlling the amplification.
If both input jacks are used (IN1, IN2), the two VCAs will operate independently.
The output of VCA1 will go to OUT1, the output of VCA2 will go to OUT2.
If there's no jack in IN2, the two VCAs will be cascaded, and the output of VCA1 will go both to OUT1 and as an input to VCA2.
This allows this module to be used to process both the MIDI Velocity and the envelope of an audio signal.

MRG Synthesizers (mrgsynth) are handmade modules designed by Gianluca Guida in Cambridge, UK.
These modules are the result of my growing interest in music synthesis. MRG modules implement high quality classical building blocks of subtractive analog synthesis, with a focus on simplicity and versatility.
I approach synthesizers as technical instruments to explore that marvellous connection between mathematics and brain that we call music. Being technical instruments, MRG modules are designed to be conceptually simple (i.e., do one thing well), and their panels are meant to be concise, and somewhat dry and rational.
MRG's most common modules are part of the MRG 4HP series, a series of small, narrow but powerful and elegant modules.
