Glitch art refers to the use of audio signals and audio effects to modify images. The Cycling74 BEAP modular synthesizer system is particularly suited to glitching. This article provides a prototype for the first glitch modular system in Max7. This is very advantages for glitch art, because numerous audio modules are already available in BEAP for waveform generation, filtering, and effects; the results can be viewed in real time; the modular system is openly extensible to support many artistic variants; and modules can be customized for unique results.

This is the first glitch module for BEAP. It reads an image file at its original resolution, then scans the image pixels row by row, like a traditional TV, at audio rate. As it reaches each pixel, it can adjust its color by mixing its RGB value with audio inputs, scaled to fit in the +/-5 CV audio-rate module interface for BEAP modules, then stores it in the same location. Additionally, the read point and write point can be modulated. The rasterizer signals, HSYNC, VSYNC, current RGB source value, and horizontal scan frequency, and vertical scan frequency are output as CV values.

Version 2 is now available that fixes and includes preset storage, among other details.

Version 2a is available with some minor fixes:

Preset module: save button works properly


Lfo module: sine and random waveform fixes. More robust copy/paste. Minor change to wave display
