Plog, from Intellijel Designs, is a dual logic module with two programmable logic sections with both toggle and data flipflop blocks. Each of these four sections are normalled together in useful ways. It is useful for a variety of applications including timbral construction, self-generating patches, and working in tandem with basic sources to produce complex sequences.
Dual 3-input logic blocks. input Z is normalled to input Y and Y to X in order to allow 2-input and 1-input logic modes
Bi-polar voltage control of the logic types for section A and B with dedicated attenuators (positive voltages move the type forward, negative in reverse) inputs X and Y from logic block a normalled to inputs X and Y of logic block B. Output B normalled to input of the toggle flipflop via jumpered normal (can be removed) on back of PCB
Toggle flipflop has dedicated pushbutton for manual triggering of toggle state - hold the trigger button for about 1 second it will disable the trigger input jack and become a simple tap clock
Output of T flipflop is normalled to CLK input of D flipflop (inverse output of D flipflop also internally normalled to D input) so that by default the D section also acts as a toggle – this allows /2 and /4 clock dividing
Save or load the logic section as a preset for easy recall of patches
Module can be run at audio rates in order to generate interesting digital sounds
