Basic Patches

On this page you will find several simple patches to demonstrate module functionality and signal flow in the LZX Visionary modular video synthesizer system.

Color Bar Calibration

Required Modules: 1 Color Video Encoder (CVE), 1 Video Sync Generator (VSG)

While the LZX Visionary system’s output will always produce a valid video signal, there may be situations where you will want to ensure that the output of your system is properly adjusted for color balance in a studio or production environment. For this purpose, the Video Sync Generator module provides color bar outputs to use as a calibration reference. LZX Visionary uses 0-1V signals, so these color bar outputs are at an amplitude of 0.75V to provide standard color bar saturation level of 75%. In this patch, the Color Bar outputs are fed directly into the Color Video Encoder, and attenuverter/bias controls are adjusted for the desired output color balance.

Basic Colorizer Workspace

Required Modules: 1 Color Video Encoder (CVE), 1 Video Sync Generator (VSG), 1 Triple Video Fader & Key Generator (TVF), 1 Video Blending Matrix (VBM)

This example demonstrates a simple workspace patch. A workspace patch chains together processing modules ending with the Color Video Encoder, and serves as a specific way to route signals to the triple color channels of the CVE. The basis for the colorizer patch involves taking a single black & white video signal out of the VSG’s luma (Y) output from an external source, such as a DVD player or camera. The signal then feeds all of the A channel & Key inputs of the Triple Video Fader & Key Generator. Threshold controls are then used to divide the input signal into varying amplitude bands. These keys are then fed into the Video Blending Matrix’s top columns. The sum outputs of the VBM feed the encoder. Therefore, for each output band you have three knobs with which to adjust that band’s Red, Green & Blue values. The patch could then be expanded upon by inserting control voltages and other signals into the TVF and VBM.

Using the Voltage Interface I

Required Modules: 1 Color Video Encoder (CVE), 1 Video Sync Generator (VSG), 1 Voltage Interface I (VI1), any external EuroRack module

LZX Visionary modules can receive 10V signals from standard EuroRack audio and CV modules, however they expect a voltage range of 1V in order to get optimum operation out of the module controls and high bandwidth circuitry. In some cases, it won’t matter — but in others, the Voltage Interface I (VI1) module can be used to convert external voltages to the correct range. In this patch, three waveform outputs from the Bubblesound uLFO are patched into input channels on the VI1. The VI1 gain and bias controls are adjusted so that the two clipping notification LEDs are NOT lighting up at any point. The VI1 outputs are then fed straight into the Color Video Encoder to create a morphing, voltage controlled color field.
