The TINYSIZER voltage controlled or variable gain amplifier VCA analog modular synthesizer module

Unspectacular they may be, but VCAs are very important modules used for controlling modulation depths as well as audio levels. Tinysizer has a total of 4 linear VCAs, one of which includes a pair of knobs on the panel:

VCA 1, 2 and 3 all have equivalent circuitry and exactly the same set of inputs and outputs. VCA 4 has more functionality: The amount of amplification is determined by a voltage at the CV input (patch point 15) as well as by a bipolar OFFSET and overall GAIN.

Note: The output of VCA 4 is connected directly to the VCA4 SIGNAL OUT jack socket - the only "prepatch" in the entire system. Although this socket will often be used as Tinysizer's main audio output, remember that VCA 4 can also handle control voltages - in which case one or two auxiliary outputs can be used for the audio signal(s)

This is the mainout of the TINYSIZER for audio (or control voltages) signals, or use it for your headphone.

Why TINYSIZER?

I think it´s one of the smallest patchable mini analog modular synthesizer in the world!
