STRUCTURE SD is a visual generator module that is based internally on an OpenGL GLSL node based platform. It uses the concept of node structures to push visuals through the system.

STRUCTURE SD contains a video input system that you can select between two formats, Composite video or LZX 1V RGB (with sync applied to rear of module). The Composite input does full color decoding. Input video can be mixed through effects, with other generators, effected with audio, etc.  Input video can be NTSC or PAL, 480i.  STRUCTURE SD auto detects and converts video inputs.

STRUCTURE SD contains two mirrored video outputs, both composite, selectable to NTSC or PAL 480i.

Two audio rate CV inputs can be used with audio nodes to generate audio based visuals, effects moved by audio waveform, XY plotting of audio inputs, or just used at low frequency CV inputs when not using audio nodes.

Three CV rate inputs can be used to modulate a variety of controls on each node.

All CV can be set independently to 1V or 5V expected input. Each CV has a scale control and a positive offset control for fine tuning incoming CV voltages.

A joystick can be used to modulate controls in real time, or used to record motion information that is played back in a loop.  In addition, the joystick has a metal hat for nice weighted movement.

STRUCTURE SD can also generate 3D graphics, animate properties of the 3D objects, and allow you to map and node type to the texture of the 3D objects (like video).

Three gate inputs, usable by local buttons as well.

Three macro knobs on the top right, allow for global changes to the output node which are user configurable.

STRUCTURE SD has a USB input, which you can attach MIDI interfaces, MIDI keyboards, controllers, etc, or even a standard PC keyboard or numeric keypad.  You can assign actions or state changes to trigger from any of these input sources.

SDCARD on front and back.   Backside SDCARD stores system, front side stores user presets, images, configurations, objects, custom shaders, etc.

STRUCTURE SD has a full color 320×240 preview screen which also provides lots of feedback when using.

STRUCTURE SD requires Eurorack power (it uses both -12V and +12V to operate). The barrel jack on the back allows you to use a different +12V power source to alleviate the load on your main euro rack supply if it cannot handle the current.  IT STILL REQUIRES BEING HOOKED TO EURORACK POWER EVEN IF USING SUPPLEMENTAL POWER!

STRUCTURE SD current draw

  • 440mA +12V (with no USB devices, it will go up for every device added)
  • 30mA -12V
  • Module depth 48mm

This module does not use +5V from euro rack power.
