"Универсальный аудио - CV стерео-процессор от Twang."
"A versatile stereo audio-to-CV processor from Twang."
Crossfader/Polarizer/Panner with a twist.
CPP is a powerful processor for audio, but it also can be used with CV signals. It’s a great tool to work with a stereo field particulary and with a sound design in general. It can be a multitrack bus or individual panner. For small systems it can be end-of-chain mixing tool with vc crossfaders, vc panners and VCA’s.
The module consists of 4 sections: 2xCPP, Mid/Side, 2xVCA.
The first two channels are identical and the module is named after them. We have two signal inputs going to the crossfader, controlled with the knob and cv input. Additionally, there is a handy attenuverter to make cv control easier. After crossfader the signal goes to polarizer, which is actually a bipolar VCA and can be used as classic amplifier, ring modulator or inverter. It can be bypassed symply by routing the signal with switch directly to panner, then it can work independently. There is a dedicated input C for it. Thus we can get 3 input mixer inside one channel. In addition, it has 5V offset switch wich can be useful while processing a cv signals. The final stage is panner. It also has cv input and send our signal to sum in stereo.
The second channel is identical to the first one.
The third section is a “secret weapon” of stereo sound design – Mid/side encoder-decoder. L and R inputs are transforming to Mid and Side signals and then can be transformed to wide stereo field. There is no knobs to control this, but there a lot of ways to use it with other on board sections or with other VCA, VCF or FX modules.
The last fourth channel is a pair of VCA’s. There is a signal input, cv input and signal output. Both are the same and have level control knobs.
Finally, all input signals are summing to master output with deficated level control knob. If we use a channel’s individual output, it will be subtracted from the main mix.
