oculus mendax

glsl shader visualization / video synthesizer module

the "oculus mendax" module gives you a simple, versatile and customisable visualisation tool in hand
to spice up your rack or your performance on stage without the need for additional soft / hardware.

the idea is simple:

get ( and transpose ) or write glsl es 2.0 code - copy it on a usb-stick, add some custom pictures,
pluge the stick in the module, choose from your rack cv, clock, trigger, gate or even audio signals
and plug them in one of the eight inputs, choose the input mode, enjoy the show.

many "presets" re already availeble!

key features:

• 6HP / 32mm deep
• ~300mA @ 12V+
• 8 CV in ( 0 to 5V+ / protected ) - 4 are normalised to pots ( double function: inputs or menu )
• intuitive 2 button / 4 pot menu to set up input modes like:
  - change shader ( can be randomized - see below )
  - change picture ( also possible inside the shader code )
  - input randomizer ( for trigger / gate signals )
  - audio input ( like a regular visualizer this mode controls various parameters with one mono audio signal )

many more modes are comming in future updates like ( order of implimentation ):
- load and save settings from/to a setup file
- input matrix
- internal LFO
- internal attenuator
- usb midi
- video player/slicer

• up to 32 custom fx programs ( refered as shader / fragment shader ) / current firmware
• up to 32 custom pictures ( .bmp format to process with effects ) / current firmware
• rgb iluminated pots for visual feedback
• overlay menu / display for parameters / settings

this module also supports composite output,
either availeble via modified fronplate or via breakout board ( currently in development ) with integrated composite-glitch-mixer...

further updates and changes on demand are indeed possiible, suggestions welcome!

single file c++ code ensures a small firmaware ( no linux / raspian ),
fast boot time ( depending on the custom content you load on startup ),
plenty of memory left for ( future feature ) video files, fast calculations
and realtime / latency free visual output ( i included an option to "limit" the framerate )
depending on the complexity of the shader code you can have up to 200 fps,
and even just 10 fps due to the processor architecture of the raspi not flicker :)

more infos on youtube ( and very soon some walktroughts ):

some of the "effect-programs" ( gl es 2.0 ) so far:

"legal" disclaimer: im a private person who happens to build some more modules than i need for my self.
i spend the best part of the last 12 month and most of my money on reserching, learning, designing
and testing this module and i am happy to share the joy of owning/using one with you but

i cant nor do i want garantee availability or shipping dates!

just get in contact with me, we will find a way.
